Precision Measurement Technology with MCOSMOS

4 v3.0 26.11.2007

2 Precision Measurement Technology withMCOSMOS

MCOSMOS is a program for recording, evaluating and documenting geometries

in 3D co-ordinate measurement technology. The "M" stands for Mitutoyo,"COSMOS" stands for "Controlled Open System for Modular Operation Support".

With our experience gathered in more than seven decades, Mitutoyo countstowards the pioneers of precision measurement technology all around the world.Building on our roots in Japan, our network of branches, manufacturing facilitiesand distribution centres spans 26 countries and counts 4500 employees. Andthere are additional Mitutoyo agencies in roughly 60 other countries. Last but notleast the specialists in software development of our German TechnologyLaboratory (CTL) are setting world standards! Instrumental for their work,however, are also the requirements of our customers who seek to safeguard theircompetitive edge by employing state-of-the-art measurement technology.

We have made a point of developing user-friendly software. This includes, forexample, the graphical support. The illustration above shows an example for circle

measurement with CAT1000.

Measurement data are recorded with a co-ordinate measurement device. Thismay be either a CNC-controlled co-ordinate measurement device or a manuallymoveable or a 2D-measurement device. Furthermore our devices and softwaresupport further systems (e.g. probing systems, rotary tables etc.) that areexpanding the huge range of measurement options. The comfortable menunavigation is supported by the integration of photos, of CAD-drawings or audiodocuments.

For generating new measurement programs, a virtual driver system is at your

disposal. This also applies for the rotary table. In addition to various protocoloptions that can be defined by the user also the output to third systems, e.g. QS-STAT, Word or Excel, is possible.

Purpose

26.11.2007 v3.0 9

5 PurposeGEOPAK is a program for recording, evaluating and documenting geometry. Aco-ordinate measuring machine is used as the recording device. This can be aCNC-controlled co-ordinate measuring machine, a manually positioned version ora 2D measuring machine. In addition to this, these can be further supported byour equipment systems (e.g. probing systems, rotary tables / etc.), which expandthe range of measuring options. An easy to use menu mode is supported by theintegration of photos, CAD-drawings or audio documents.

In addition to a series of protocol capabilities to be defined by the user, it is alsopossible to output to external system such as QS-Stat, Word or Excel (for detailsregarding customer-specific protocols refer to chapter "10 Output").

Performances and Features

10 v3.0 26.11.2007

6 Performances and Features

6.1 Modes of Operation

Our central measurement program GEOPAK offers several operating modes.

The creation of measurement programs in the learn mode.

The execution of measurement programs in the repeat mode. Inorder to verify your measurement programs, you can run them in thesingle step mode. Skipping of already executable measurementprogram sections is also possible.

For a most effective repeat mode, you create Manager Programsusing the Manager Program Editor. You can use Manager Programsin the CNC mode for automatically measuring multiple work piecesin sequence without requiring an operator intervention (man lessshift).

The parts may also be of different kind.

The co-ordination of the part programs is carried out by theManager Program.

The administration of the Manager Programs with the ManagerProgram Editor is similar to the administration of part programswith the PartManager.

6.2 Editing mode

You correct your measurement programs using the GEOPAK Editor.This Editor serves also the purpose of creating measurementprograms offline. Relearn is possible from the repeat mode.

For the selection of a mode of operation you simply click with the mouse on oneof the symbols in the PartManager (picture above). This is already the beginningof the elegant operator prompting feature.

Should you, however, prefer to use menus, get to the desired dialogue and clickon the clearly designated functions (picture below).


11/41


26.11.2007 v3.0 11

6.3 Links/Settings in PartManager

GEOPAK is closely linked with the PartManager as already in this multifunctionalcentre, the options form a major part in the menu "Settings". This is where youalready define the configuration with which you intend to work off your

measurement tasks (see ill. below).

The PartManager is a distribution and administration centre for all processes

concerning your measurement tasks. Together with the administrator thePartManager safeguards a password-protected working. To achieve this, theadministrator generates different users and assigns appropriate rights. Each useris assigned a unique and individual password. Afterwards, the user can changehis password at any time with the aim that the password is no longer known tothe administrator.


12/41


12 v3.0 26.11.2007

6.4 Creating, Managing and Editing MeasurementPrograms

When measuring individual parts in learn mode the measuring commands aresaved automatically, so that a part program can be generated. Clicking themouse on the symbols (icons) or the menus creates the inputs. The text fields areadministered via the keyboard.

External influences such as the condition of the material (temperature coefficient)are taken into consideration in the temperature compensation. In the meantime,this temperature compensation can also be used by manually operated CMGs.

With revision management that is controlled via user rights we provide a featurethat ensures that only checked part programs can be used in the currentmeasurement operation. Changes need to be recorded, i.e. part programs canonly be employed in the current measurement operation after the changes havebeen tested and recorded.

6.5 Start Assistant

You can also control the program start for the learn mode with the "StartAssistant". This Start Assistant has been designed to give you the possibility for astandardised learning of the part program start. Basically, you can configure theStart Assistant as regards its possible settings yourself, including the followingcomponents:

probe,

co-ordinate system,

CNC-parameter and CNC on,

print format specification or

protocol selection.


13/41


26.11.2007 v3.0 13

6.6 Probes and Probe Change Systems

The user-friendly calibration of the probes and their management gives thesecomponents a special significance. We also use the most up-to-date technologywith regard to probe changing and probe-tree changing systems.

Further developments in both the hardware sector as well as in the softwaresector have opened up new possibilities with regard to measuring workpieces.

For the measurement of a complex workpiece you don't use a fixedprobe, but a pivoting probing head such as, e.g. the PH 10 (picturebelow).

An important link in the series of systems supported by us are also

the probe-tree changing systems. These systems enable you toautomatically change various probing systems. This comprises theprobe changing system types MCR 20, SCR 200, SCR 600, SCR 6,SCR 800, ACR 1, ACR 2, ACR 3, the Manual Changer and theVirtual Changer.After the definition of a probe tree system an easy and comfortablechange of this system is possible.

The ACR 3 allows you to use two modules. Consequently, there aremore than four different probing system at your disposal.

You can also use the FCR25 with all its possibilities, as the probetree changing systems support all conceivable combinations.

Furthermore, Mitutoyo makes it possible to combine different probechanging systems, so-called racks. This enables an automatic and


14/41


14 v3.0 26.11.2007

quick module change. The measuring tasks requiring differentprobes can also be automated.

"Probing Systems with continuous Point Recording" (AnalogueMeasurement Probes" are capable of recording a great number of

points requiring, however, less time than triggering probing systems.This comprises the probe types MPP2 / MPP4 / MPP100 / MPP300/ MPP10 / SP600 / SP25 / SP80.The SP25 requires a warming up time of several minutes. Exactmeasurement is only possible after this waiting time.

With the micro probe UMAP you can measure very smallworkpieces. This is for example a fuel injection nozzle. The smallestprobe diameter is 30 micro meter.

The REVO probe allows the measurement of cylinders at highspeed. This probe head moves on a circular path while the CMMmoves alongside the element axis.

The PHS1 is a motor-operated probe mounted on two axes. Thisprobe can be swivelled continuously to all positions. For positioningthe laser probe and the star probe, an optional third axis is available(PHS3). The PHS1 adapter arm can be exchanged over the treechange system ACR2.

The "WIZ-Probe", a laser-operated probe, enables themeasurement of surfaces by scanning.

With the program MetrisScan, also surfaces with more than 1000points can be measured in GEOPAK on condition that your CMM isequipped with a probe changing system.Then, GEOPAK creates the co-ordinate system and initiates theprobe change. MetrisScan also performs the evaluation andadministration of the measurement results.

An optical probe is used for measuring workpieces which are notsuitable for being probed with a contact-type probe (easilydeforming materials). You will certainly perform opticalmeasurements also in cases where, e.g., bores are too small forbeing measured using a triggering-type probe.

When working with a SpinArm, you can use this measurementinstrument also as a "mouse". Thus, you can stop the measurementprocess and, if required, change some of the parameters. You can

also start with a new measurement task. The functions of the twobuttons of the SpinArm correspond to the functions of the left orrespectively the right button of a standard computer mouse.

6.7 Support of Special CMM-Control

MCOSMOS supports the machine control developed by Mitutoyo, including e.g.CMMC-5 and UC200. To support also CMMs from other than Mitutoyo sources,our product range also contains machine controls from Renishaw, e.g. UCC1 andUCC2. You will need one of these controls when, for example, working withRenScanDC or the Revo probe.


15/41


26.11.2007 v3.0 15

6.8 Support of Indexing- and Rotary Tables

Indexing tables

Working with index tables you only need one fixture to measure the workpiece on

different sides.Following index tables are supported:

Mitutoyo Index Table

Anorad

Rotary tables

Working with rotary tables it's not required to go around the workpiece with theprobe.Following rotary tables are supported:

Mitutoyo Rotary Table (MRT). Among the supported rotary tables,the Mitutoyo Rotary Table (MRT) is the only one that is also suitable

for scanning.

Kugler-CPD20

NSK

6.9 ProbeBuilder

With the ProbeBuilder we offerthe option to configure yourprobe structure with graphicsupport. No manual inputs are

required. You only need toclick on individual components.The components belonging to aprobe system are pre-sorted bythe program in a way that youcan only select suitablecomponents.

The configuration is opticallysupported so that you can seeat any time which steps youhave taken.

Four different basic views areavailable and you can also turnand rotate your probe in anydirection.

Define probe: Furthermore, the ProbeBuilder offers a tool that is responsible forthe alignment of the probe stylus definition (A-, B-angle selection and setting) andthe visual display of the current stylus status.

Generate part programs:You can use the ProbeBuilder for calibrating severalstandard probes. However, this function is only useful for CNC-operated CMMs.

The system supports

6.10 Co-Ordinate System

6.10.1 Forming Co-Ordinate Systems

GEOPAK offers a wide range of alignment options.

The three necessary steps

Align plane,

Align axis, and

Create origincan be performed in different ways.

Single commands allow to measure any elements and to use themfor forming a co-ordinate system. Recreating a co-ordinate systemis possible at any point of time while the part program is running.

For frequently occurring alignment patterns, we have createdmodels capable of reducing the required steps to a minimum. The"Pattern Alignment" can be activated by a simple mouse-click (seepicture).

In connection with the automatic element recognition (see chapter4.2.3), the alignment according to most of these patterns can alsobe executed automatically.

Moreover, it is possible to perform a plane alignment using sixdefined co-ordinates (car grid alignment, RPS alignment).

The co-ordinate system can be determined by a best fit as well (fordetails refer also to chapter 7.6 Best Fit).

Of course, you can store any formed co-ordinate systems and load them increating a part program, so that the part program can run without requiring anyfurther actions.


17/41


26.11.2007 v3.0 17

6.10.2 Using Co-Ordinate Systems

The table co-ordinate system (table position) defines the position ofthe part or pallet on the CMM table.

The pallet co-ordinate system enables you to automatically measure

in the CNC mode various workpieces on one or more platens(pallets) at different positions on the machine table (see picturebelow).

The pallet co-ordinate system defines the position of theworkpiece on the pallet.

From storage to graphics

The co-ordinate systems can be rotated about any angles andmoved by any co-ordinates.

You can use up to 32 767 co-ordinate systems in one partprogram only. At any time, you can call up the co-ordinates ofthe machine co-ordinate system and the current workpiece co-ordinate system.

You can get a graphical display of the relation of the current co-ordinate system to the machine co-ordinate system.

Co-ordinate system types

The following co-ordinate types are offered.

Cartesian co-ordinate system

Cylindrical co-ordinate system (2D polar)

Spherical co-ordinate system (3D polar)

7 Measurement

7.1 Recording Measuring Points

Measurement points can be recorded as follows:

Enter the co-ordinates via the PC keyboard

Fixed probe and foot-operated switch

Triggering-type electronic probing systems, also rotary / pivotingsystems (refer to the information included already in chapter"6.6 Probes and Probe Change Systems")

Measuring-type electronic probing systems(CNC co-ordinate machines only)

Contact less with laser-operated probe or camera

You have the possibility to automatically calibrate several probe positions of arotary / pivoting probing system.

Measurement points recorded by mistake can be deleted again immediately afterthey have been recording.

7.2 Geometric Elements

7.2.1 The Elements One by One

GEOPAK makes it possible to record the following elements:

Single point Cylinder

Sphere Step cylinder

Line Inclined circle

Ellipse Plane

Taper Option: ContourGears andsurfaces

All geometric elements can be generated in GEOPAK also theoretically, e.g. by

input or as results of calculations.Excluded are gears, surfaces and step-cylinders.

Graphics related to the element (picture below shows a gauge ring) and thecurrent machine position can be displayed during measurement.

The number of the points to bemeasured is displayed in additionto the element and machineposition.


19/41

Measurement

26.11.2007 v3.0 19

7.2.2 Methods of Calculation

By default, the elements are calculated in accordance with theGauss's method. The calculations have been certified by PTBto the highest accuracy class.

The calculation of the elements line, circle, plane, cylinder andsphere can be based on the Chebyshev geometries.

Upon request, each element is given an element storagenumber and can be called, at any time, into every co-ordinatesystem and every co-ordinate system type.

In a part program you can assume that there is an elementmemory of unlimited size.

Consequently, every geometric element can be defined - intheory - by an unlimited number of measurement points.

All geometric elements and element linkages can be projectedinto the planes XY, YZ and ZX or processed in space.

The individual measurement points can also have beenmeasured with probes of different size.

7.2.3 Automatic element recognition

The automatic element calculation makes your work much easier. This functionserves to gather single measurement points and their corresponding probedirection. These points are used to create elements that are graphicallydisplayed. Furthermore, the system supports the user by acoustic means. Theuser needs no more keyboard or mouse but can concentrate on positioning themeasurement points.

After the plane alignment you can additionally define anautomatic clearance height to allow an immediate execution ofthe part program.

For a stored element, you can cause the system toautomatically call up the dialogue for the tolerance comparison.

Thus, it is possible after the first three detected elements toexecute an automatic alignment.

7.2.4 Additional elements for the measurement ofbodyworks

For the measurement of bodyworks, several more elements are required. In theillustration below you see the symbols we use in MCOSMOS (from left to right)for: rectangle, square, oblong hole, hexagon, triangle, trapezium and drop form.These elements are each defined with their respective minimum point numberand can be tolerated by position and location.


20/41

Measurement

20 v3.0 26.11.2007

7.2.5 Element Linkages

You can work with the following linkages:

Create Distance. Using the Distance function the operator canselect from a table or a graphics the elements between which the

distance has to be calculated. The distances of the currentlyselected elements are directly displayed as a spatial distance andas distances along the co-ordinate axes (inner distance, outerdistance, projected and spatial distances, distances along a givendirection).

Create Angle. Using this function you can create projected andspatial angles In each case, the supplementary angle to 180 isproposed as well. The angle output is possible in the decimalsystem or in degrees, in minutes and seconds. During the selectionof the elements for the angle calculation, the angle between the twoselected elements is immediately calculated and indicated.

Create Intersection Element. It is possible to create intersectionpoints, e.g. from circles, lines and other elements.

Create Symmetry Element. These functions are used like the"Create Intersection Element" function.

Create Connection Element. Here, single elements are connectedto form new elements. For instance, it is possible to calculate fromthe centres of several bores a connection element circle, the holepattern.

Connection Elementscan also be created through themeasurement points of other elements. It is, for instance, possible tomeasure several circles and, using the measurement points of thecircles, to additionally calculate a cylinder.

Create Tangent. It is possible to create a tangent from a point to acircle and joint tangents of two circles (inner and outer tangents).The point can then be selected as one of these points of contact.

26.11.2007 v3.0 21

7.3 Element Graphic

It is possible for the measured elements circle, line, plane and cylinder to display

them graphically or output them by means of a printer.

The graphic shows:

the ideal element

the upper and lower tolerance

the position of the individual measurement points

The results of your measurements are displayed graphicallyand expressed in numerical values.

In addition, you get the following parameters:

the co-ordinates of the element

the co-ordinates of the measurement points with the maximumor minimum difference

the element storage number

the maximum difference and the variance the nominal size

the actual size

7.4 Graphic Mode

The recorded geometric components are graphically displayed in this mode andyou can choose to display them in a screen window or over the full screen. Theelement storage numbers are shown when a full screen display is used.

Furthermore, co-ordinate grids can be overlaid and the displayed graphics can beprinted out.

An isometric representation will support and enable you to opticallyrecord the three-dimensional character of the elements.

In addition to this, graphics can be displayed for specific functions,e.g. the position of the current workpiece co-ordinate system relativeto the machine co-ordinate system.

7.5 Nominal-to-Actual Comparisons

GEOPAK provides the following nominal-to-actual comparisons:

Angle

Distance

Element feature

GEOPAK automatically proposes the possible results ofmeasurement for the element concerned (e.g. for a circle thediameter, the radius and the circularity). Straightness, circularity andflatness can be displayed graphically as well.

Straightness Circularity

Flatness Diameter

Form of cone Form of sphere

Form of cylinder

Position

Cartesian co-ordinates: X, Y, Z

Cylinder co-ordinates: Radius, angle Phi + Z

Sphere co-ordinates: Radius, angle Phi + Theta

Concentricity

Coaxiality

Orientation with ...parallelism, perpendicularity and angularity

Symmetry with ...point element, axis element and plane element

Simple runout tolerance

Variables (results of other calculations)

Furthermore, GEOPAK provides a tolerance table containing the standards ISOR/286, DIN 7168 and DIN 16901/A. This means, instead of upper and lowertolerance you can enter, e.g. the tolerance class H7.

You also may create further tolerance tables, e.g. for casting tolerance or workstolerances.

7.6 Best Fit

The best fit enables you to rotate and/or move the elements of a workpiece insuch a way that the sum of the deviations from the nominal positions of theelements is as small as possible. This is based on the "Gauss's Least ErrorSquares Method". For continued measurement you can define a new workpiececo-ordinate system using the result of best fit.

The use of variables enables you to tap into a wide range of calculation options.The user is able to define placeholders for numerical values using thesevariables, which can be used for any input. The variables for the input can be

selected from a list. You do not have to enter the name manually. The values ofthe variables can be used and modified in the formulas. In particular, thevariables enable you to set up flexible part programs, which can be used not justfor an individual part program but for the entire family of part programs as well.

Variables can also be entered with names and used for polar co-ordinates.

It is also possible

to define text variables,

to include the results of nominal-to-actual comparisons intovariables,

to use the current temperature or other system parameters as avariable for the remaining measurement cycle.

7.8 Dialogues for the Input of Variables

For the input of multiple variables you can create dialogues in which the operatoris asked for the contents. You can easily create these dialogues using theDrag&Drop-function via the dialogue designer.

7.9 CNC Mode

7.9.1 Measurement PointsEvery element can be measured with single points.

There are the following possibilities:

Enter the workpiece contact point and the probing direction

Enter the start co-ordinates and the probing angles

Enter the start co-ordinates and the imaginary target co-ordinates

When using the function " Measure point on circular path", you candetermine a measurement point at the pocket by moving the probe

on a circular path (see ill.

below).

1 Starting point of circular movement

2 Probe vector perpendicular to radius

3 Measurement point

4 Centre point

5 Radius

6 Start angle

7 Axis of co-ordinate system

(depending on movement level)

7.9.2 Movement

A defined approach to each measurement point is possible.

The automatic movement of the Co-Ordinate Measurement Machineis possible using the absolute and the relative movement methods

and also the approach of the machine to the start position.

Absolute movement takes the workpiece co-ordinate system asits reference.

Relative movement uses the last stored position as itsreference..

Along a single axis

Along a circular path.

7.9.3 Measurement Macros

In addition to the single points, several measurement points can be generatedautomatically as well, using "Measurement Macros" for this purpose. Thispossibility exists for the element Circle, Line, Plane, Cylinder, Inclined Circle.

7.9.4 Combination of Measurement Macros

Elements can also be measured by reasonably combining various measurementmacros.

Example:

For the automatic measurement of a plane, you can use several linemeasurement commands instead of the automatic plane measurementfunction.

All CNC parameters such as measurement or movement speed and thesafety distance can be set by default and changed as often as desiredwhile measurement is in progress.

The automatic measurement and movement capabilities can be used inthe learn and repeat modes, provided there exists a workpiece co-ordinate system to be used as a basis.

The existence of a measuring-type probing system allows the elements tobe recorded in the scanning mode, too.

For the automatic measurement of lines and circles you can additionallyuse a filter, for example, for the vibrations of the CMM.

7.10 Scanning of Known Elements

The following four elements can be scanned using a "Measuring Probe"

Line,

Circle,

Cylinder, and

Plane.

Known contour

A scanning probe can be used on a surface and, as shown in theillustration, can scan a sealing border. The points of the actualcontour are used for the calculation of the movement path. Thesequence is similar to the PHi-Z-scanning, i.e. with a known contouras the leading element instead of a circle.

Measuring with a scanning speed of up to 100 mm/sec is possible, provided yourCMM has a controller which enables you to scan known elements.

Scanning of Cylinders

For the scanning of cylinders you should know that only solid cylinders can be

measured.Measurement will be performed in spiral form, if your controller has the "Scanningof Known Elements" option. If this is not the case, single circles, one above theother, will be measured.

Scanning of circles at high speed

The function RenScanDC is an option you will use to quickly scan circles.

If the nominal data of the element are known, the machine control willimmediately scan the element at scan speed. By the one-off scanning at learnmode speed, the machine control memorises the nominal data and issubsequently able to perform the measurement at scan speed.

This is an exclusive function of the Renishaw UCC machine control.

7.11 Dual Arm Operation for the BodyworkMeasurement

Between two measurement stations (horizontal arm machines), a car bodyworkcan be measured simultaneously from both sides.

This is supported by the following function:

Protection against collision of the two arms;

Communication of both computers for

using a common co-ordinate system,

the transfer of the elements and raw data (measurementpoints);

Synchronisation of the two part programs on the two CMMs.

This is why it is possible that one of the two computers can generate a completeprotocol of the measurement on its own.

In case that an element can only be created by measurement points from bothCMMs, the element "Container" is available. This element only serves thepurpose of gathering the measurement points and transferring the measurementpoints to the other computer.

7.12 Displays

Apart from graphic support, the GEOPAK main window provides continuousinformation on the measuring process. The following options are available:

a result box,

an element list, a "Machine Position" window with temperature display, and

an axis indication and

a status line, too.

As far as the activation and positioning of the windows is concerned, the programproposes you a default setting. Though, in the end, it is up to the user to decidewhich information to view and where.

Status line

The status line of the main window (see clipped

out picture) provides the user with current information including but not limited tothe following:

Type and number of the co-ordinate system,

Probe number,

Used measurement unit,

Connected devices, etc.

Storing and segmenting window positionThe window positions can be stored and ...

the main window divided into segments. This is of special importance when you

use CAT1000S or CAT1000P at the same time. So there is no need for you tochange from one window to the other, but you can handle both programs on onescreen.

Special Functions

8 Special FunctionsFor challenging measurement tasks GEOPAK offers a variety of specialfunctions.

Working with subprograms (also in learn mode) and branchings isnow regarded as something normal.

The "Probe Edge Point" function enables the sheet plate deflectionto be compensated for in order to avoid probing faults. You canhave the sheet plate rough-probed up to three times.

One-flank scanning is now possible also with the rotary table.

Using the "Position" function you determine whether the positiondeviation of a point is still within the tolerance. "Position ElementPlane" enables you to tolerance the position of a plane which islocated approximately parallel to a base plane. The same is true for

the "Position Axis Element" function, too. The "Groove Point" function allows a measuring-type probing

system to go, e.g., into a V-shaped groove deep enough for the ball-shaped probe tip to touch both flanks simultaneously.

By means of "On Error Goto" and the associated functionsGEOPAK will activate, beginning from version 2.1, a user-definederror treatment process.

Upon the occurrence of an error, GEOPAK addresses a"Label".

The declaration of this label is identical with the declaration oflabels for a goto instruction.

The declared labels can then be used both for an "on errorgoto" situation and for the "normal" jump commands(branchings).

It is possible for you to have part drawings displayed. Thesedrawings are inserted into the part programs and displayed for theirrepetition.

Furthermore, there is a programmable scale factor available toperform e.g. compensations.

A look at your partdrawing, that is on

your PC, makes yourmeasuring job

considerably easier.

User-Friendly SoftwareWe have endeavoured to develop user-friendly software and we have followedthis up with a series of functions, which will make your daily work easier, eventhough only a few can be mentioned at this point.

As an example, you can have a picture displayed for each workpiece,

play back an audio document,

send e-mails and SMS,

enter comments.

It is certain that you will be pleased to be able to delete both the last measuredpoint as well as the last step.

9 GEOPAK and other programs

9.1 GEOPAK and CAT1000S

The co-operation of the programs GEOPAK and CAT1000S is characterised by

the following options:

GEOPAK performs the measurements,

CAT1000S performs the specific evaluation,

Several GEOPAK functions can be called up directly in CAT1000S,including

storing of CAT1000S actual data via GEOPAK, for example inDMIS-format.

archiving of CAT1000S measurement data and

the output of CAT1000S protocols and graphics.

9.2 GEOPAK and CAT1000P

CAT1000P serves the purpose of supporting the creation of a GEOPAK partprogram using the CAD data of a part.

When CAT1000P is used in conjunction with the virtual CMM, it is possible toprogram measurement tasks as soon as the CAD model exists.

This is based on the condition that the output of the models is performed in oneof the supported CAD formats.

CAT1000Pcan be used only in connection with a CNC Co-Ordinate Measuring

Machine.

The interaction with GEOPAK means:

You can generate an automatic element measurement by a mouse-click into the CAD model. It is not necessary that the elements to bemeasured are also present as elements in the CAD model.Example:You can generate a line measurement by clicking two points on asurface or an edge within the CAD model.

There is no need for the data to be entered manually into GEOPAKfor automatic element measurement.

CAT1000P supports the elements line, circle, cone, sphere, planeand cylinder.

As is the case with CAT1000S, partition of the screen is possiblealso for the interaction GEOPAK and CAT1000P.

9.3 GEOPAK and GEARPAK

GEARPAK is an integral part of GEOPAK. GEARPAK is responsible for gear-specific tasks such as generating part programs, evaluation and the setting up ofprotocols. GEOPAK takes over the actual measuring process here.

You can use GEARPAK as an integral part of GEOPAK together with a co-

ordinate measuring machine (CMM). This combination of software and co-ordinate measuring machine renders the purchasing of an expensive gearmeasuring unit, that can only be used for this sole purpose, unnecessary.

9.4 GEOPAK and ROUNDPAK-CMM

ROUNDPAK-CMM is a program for circularity tests that complements theMCOSMOS geometry module GEOPAK.

For a circularity test usually a special CNC circularity test device with the analysissoftware ROUNDPAK is employed. This combination, however, can often not beused for large workpieces because the measurement range is not sufficient.

Therefore we have developed ROUNDPAK-CMM. The combination ofROUNDPAK-CMM and GEOPAK allows testing of circularity and cylindricity oflarge workpieces.

.

The pictures show some examples for elements that can be evaluated withROUNDPAK-CMM (from left to right: rotation inside - outside; rotation top -

bottom; spiral inside - outside and line top - bottom as well as inside - outside).

Above you see an example printout for how measurement data evaluated byROUNDPAK-CMM can be printed out in GEOPAK.

Prerequisite

For testing the circularity and cylindricity of large workpieces with ROUNDPAK-CMM and GEOPAK you will need a LEGEX-CMM and a Mitutoyo rotary table(MRT).

10 OutputInput texts (attributive characteristics) can be assigned a number using the inputfield "Position number".In output protocols (e.g. initial sample report), you can use the position numbersto define the sequence of the output data. This is how an input text can bedirectly placed in the protocol.

10.1 General

The wide range of functions in the "Output" menuis to show clearly the importance we attach to thissubject.

In principle, measurement protocols with therecorded data can be printed out via a printer.

In addition, output is possible for:

any text that may also contain resultsof the formula calculation.Here, it is possible to assign anumber to texts (attributive features)using the input field "Positionnumber".In output protocols (e.g. initial samplereport) you can use position numbersto define the sequence of the outputdata. This is how you can specificallyposition input text in the protocol.

all results of measurements

all nominal-to-actual comparisons (default setting)

Further Hints

It is possible at any time to have the current screen content printed.

The print output can be in colour, e.g. "green" for values within and "red"for values outside the tolerance.

Moreover, it is possible to store the measured values and the nominal-to-actual comparisons in ASCII files (e.g. CSV for Excel) and make themavailable for other applications (First Sample Test Report).

Protocols can also be filed in archives, the print format can be changed.

You print one job at a time, both in the learn and the repeat mode.Double-sided printing is possible as well as printing in the PDF format.

In order to meet all requirements, we have installed two programs, namely the

ProtocolManager, and the

ProtocolDesigner.

The ProtocolManager is comprised within the PartManager where it canalready be activated through the symbol, that means it is not necessary to startGEOPAK.

Output

34 v3.0 26.11.2007

10.2 ProtocolManager

10.2.1 Tasks

The measurement results generated with GEOPAK are used by theProtocolManager. At your choice, this information

is edited,

filed in archives (find archives),

printed.

Output of all data is possible by means of various layouts (templates). As a result,also the print protocols can have different layouts. The protocol proposed is aMitutoyo Standard Protocol.

10.2.2 Relearn Data

In the ProtocolManager we distinguish between "Relearn Data" and "Filed Data"."Relearn Data" constitutes information which you have created in GEOPAKduring the learn and repeat mode. In the ProtocolManager, this data serves asthe basis for a protocol which you wish to have issued.

10.2.3 Archive Data

In case you want to manipulate measurement results, you have to file themodified "Relearn Data" in an archive. Unlike "Relearn Data", this archive datacan be edited (renamed, deleted, etc.). This makes sense in cases where youwant to add attributive features (cracks in the paint, wrong colour, rust) to themeasurement results. In this way you can include also single measurement

results into the measurement protocol.

10.2.4 Data Table

First you perform these activities in a "Data Table". Nominal-to-actualcomparisons can be edited, inserted or even deleted in this table.

10.3 ProtocolDesigner

10.3.1 Tasks

The ProtocolDesigner is a tool intended to complement the ProtocolManager.

Using this tool you create new templates or modify existing templates to suit yourrequirements. The standard protocol is converted into a flexible protocol.

Based on a variety of variables, boxes, tables and graphics

you create templates for basic pages, first pages and consecutivepages.

You are supported by an assistant, and detailed documentations in the form ofonline help is available to you as usual.

10.3.2 Creative Design Capabilities

You design

the headline using, e.g. your logo,

you show the nominal-to-actual comparisons in coloured pictures,

you define new planes, or

embellish your protocols by adding so-called flags.

The Mitutoyo standard report of the layout print function can serve as a template.The first page shows a picture, some head and dialogue data as well as a tablecomprising the measured values. The following pages include only some head

data and the table with the measured values.

11 Further OptionsA series of further options add to the capabilities offered by GEOPAK (refer alsoto the list in chapter "5 Purpose").

You havealignment programs for probe changing systems

The external program call-upis programmable and, as such, canbe integrated with the part program.

A virtualmachinesupports you in machine-remote programming.

The PartManageroffers another series of options for GEOPAK:

There are, e.g., the Manager Programs capable of combiningseveral part programs to one Manager Program.

The Remote-Manager enables part programs to be started

under remote control via a file-supported port in GEOPAK, thatis from other computers within a network.

Q-PAK causes part programs to be executed automatically in await loop. A graphic user prompting system supports the user.

Also the Q-PAK dialogue shows the pictures of thoseworkpieces which were entered by the user already in thePartManager.

Communication with other control systems is ensured by our "IO-Conditions".

Use the "string coding" function to insert all sorts of information of apart program into a text line. It is also possible to output the value ofa variable or the contents of a text variable.

The scope of delivery comprises:

A part program converter from GEOPAK-3 (DOS) to GEOPAK

A port to import external part programs in the GEOPAK-ASCIIformat

Another function allows an output of the measured elements in theformats DMIS, DXF and IGES.
