CNC Machining Center Programming Manual

Programming Manual

For all Daewoo Machining Centers Using

Fanuc Controls

©Phil Misseldine 2006

Forward

While similar in appearance your CNC Machining Center operates somewhat differently

from your conventional mill. Although they may share the same work envelope and number of axis the CNC does not have the array of knobs, levers or handles associated with the manual

machine. In place of these are motors that move the X, Y, and Z-axis. The axis motors receive commands from the control, which is user programmed with a series of instructions.

It is these instructions which determine the shape of the part to be machined.

Notice of Disclaimer

This manual is intended not to replace but to supplement the control manufactures original manual. The control manufactures manual will be the final say in any

discrepancy that may evolve.

Example

S4000 M03 Set spindle speed to 4000 (S4000) and turn on spindle clockwise (M03).

A number of Words can be programmed on the same line. Once the line is complete this

forms a ‘Block’ of information.

Example of a Block

N40 G1 X20.0 Y-8.0 F80.

It contains the Words: N40, G1, X20.0, Y-8.0, F80.

The Addresses used are N, G, X, Y, and F, and the values are 40, 1, 20.0, -8.0 and 80.

The Manual Pulse Generator (MPG) or Hand Wheel is used during the setup of the machine.

This is separate from the machine control and gives better control of all axis during setup.

8

TOOL LENGTH OFFSET

When a cutting tool is inserted into its holder, the cutting edge is located at an imprecise distance from the gauge line of the holder. By specifying G43 and the corresponding offset value (H) it is possible to compensate the difference without changing the part program. This is known as the ‘Tool Offset Value’ and is unique to the tool in the spindle.

Workpiece

Tool Length Offset Distance

Z Axis Home Position

9

Tool Length Setting Method

Using a combination of the jog buttons and MPG, bring the tool down to the predetermined "Z" point.

Operators choice of 'Z' zero position.(This example uses the top of the work piece).

Work piece

Press the function key and then the [OFFSET] soft key to display the following screen.

Cursor down to Tool Number to be set. Key in value displayed in Actual Position (Relative) and press INPUT.

OFFSET SETTING

10

Tool Offset Memory 'C' (Optional)

Tool Offset Memory 'C' allows you to use the same number for

Length (H) and Diameter (D) offsets.

Press the function key and then the [OFFSET] soft key to display the following screen.

Cursor down to tool number to be set. Press 'Z' and then the 'INP.C' soft key. Position value is automatically transferred in to the offset.

If using height and cutter compensation for the same tool the program should look like this

N15 G43 Z.10 H1

N20 G41 X-5.0 D1

You also have the ability to adjust the tool length and diameter in the wear column.

OFFSET SETTING

11

Work Coordinates

Every CNC machine has a reference or machine zero. This is a position that is constant to the machine. When a machine is turned on or powered up by the operator it must first be referenced. When the machine reaches its limit switches the control registers this location as home. Using the home position as a reference you can now tell the control where the work piece is located on the machine table.

Machine Table

'X' Zero point

'Y' Zero point

Work Piece

Machine Home Position (X, Y, Z Ref. Point)

12

Work Coordinate System Setting Method

To set the work piece co-ordinates the user has the choice of six co-ordinate systems to choose from G54 to G59.

Press function key and then the [WORK] soft key to display the following page.

Method Using an edge finder or indicator locate the part datum position. Without moving go

to the work offset screen and highlight desired offset. Press

hard key X, hard key 0 soft key [measure] hard key Y, hard key 0 soft key [measure]

(Position value is automatically transferred in to Offset).

OFFSET SETTING

13

Work Coordinate System G54 - G59 and G54.1 P1 -P300

The desired Work Coordinate number should always be called at the start of every tool.

Example. N4 (.75 DIA. ENDMILL )

N5 G0 G54 G90 X-2.25 Y.625 S8000 M3

N6 G43 Z.1 H1 N7 G1 Z-1. F25

This option expands the Work Coordinate System giving the user up to 300 sets of work offsets to chose from.

Work Coordinate System Addition's are called in the following way.

Work Coordinate System Addition

Example. N4 (.75 DIA. ENDMILL )

N5 G0 G54.1 P1 G90 X-2.25 Y.625 S8000 M3

N6 G43 Z.1 H1 N7 G1 Z-1. F25

14

Linear Interpolation (G00/G01)

PROGRAMMING

All axis of the machine tool will move in linear at either RAPID or FEEDRATE traverse rates.

Any movement preceded by G00 will occur at RAPID traverse

G00 X4.0 Y-3.0

Any movement preceded by G01 will occur at FEEDRATE.

G01 X4.00 Y-3.00 F100.

These commands are MODAL and will stay in effect until changed.

Co-Ordinate Programming (G90/G91)

Absolute co-ordinate programming (G90)

In absolute programming all dimensioning is taken from a fixed point.

Incremental co-ordinate programming (G91)

In incremental programming dimensioning is taken from the last position programmed and NOT from a fixed point.

Circular Interpolation (G02, G03)

There are two directions in which you can produce an arc - G02 Clockwise and G03 Counter Clockwise.

To machine an arc the machine tool requires the following information. Tool finish position in 'X' Tool finish position in 'Y'

Arc offset in 'X' Arc offset in 'Y'

Arc offset in 'X' is represented by 'I'. Arc offset in 'Y' is represented by 'J'. Arc offset in 'Z' is represented by 'K'.

'I' is the Incremental value parallel to the 'X' axis. 'J' is the Incremental value parallel to the 'Y' axis. 'K' is the Incremental value parallel to the 'Z' axis.

Cutter Compensation (G41/G42)

Cutter compensation allows a program to be written without considering the size of the cutter.

The three G-codes used to control cutter compensation are

G41 - Cutter compensation Left

G42 - Cutter compensation Right

G40 - Cutter compensation Cancel

If your control has cutter compensation 'B' then different offset numbers have to applied to 'H' and 'D' values. Your program should look like this

G0 G43 Z1. H1

G1 G41 Y0. D11 F50.

If your control has cutter compensation 'C' then the same offset numbers can be ap-plied to 'H' and 'D' values. Your program should look like this

G0 G43 Z1. H1

G1 G41 Y0. D1 F50.

23

Cutter Compensation (G41)

G41 - Cutter compensation to the Left of the work piece.

Always apply cutter compensation at 90 degrees to the work piece. The program for applying cutter compensation should look like this.

G1G41Y0 D1 F25.

or if using cutter compensation 'B' it should look like this

G1G41Y0 D11F25.

When turning of cutter compensation the program should be as follows. G1G40Y.5.

G41 and G42 are Modal commands and will stay active until canceled by G40.

Canned (Fixed) Cycles (G73, G81, G83, G86)

Canned cycles are designed to make it easier for the programmer to create programs. With the use of a single 'G' function the canned cycle can be performed in a single block. This makes program-

ming quicker and also saves on program memory.

The formats for the most commonly used canned cycles are

High Speed Peck Drilling Cycle

G73 X _____ Y_____ Z_____ Q_____ R_____ F_____

G86 X_____ Y_____ Z_____ R_____ F_____

Legend

X = X Co-ordinate Position Y = Y Co-ordinate Position Z = Finale depth of Hole R = Rapid Plane Depth Q = Depth of Peck F = Feedrate

G80 cancels all Canned Cycles

For additional canned cycles please consult your Fanuc Operator’s Manual

26

Initial and Rapid Planes (G98/G99)

When using canned cycles the controller provides the ability to return to one of two reference planes.

G98 G99

Point Z Point Z

Initial Point Level

High Speed Peck Drilling (G73)

Example

G98 G73 X0.0 Y0.0 Z-1.25 Q.250 R.250 F20.

Unlike G83 (peck drilling) G73 does not rapid to the R plane after each peck.

When G98 is used 'Z' will return to the Initial point.

When G99 is used 'Z' will return to the R point.

Initial Point (G43 Z1. H01)Tool will stop 1.0" above part.

Tapping (G84)

Example

G98 G84 X0.0 Y0.0 Z-1.25 R.25 F10.

You must use a floating tap holder when using G84.

For Rigid Tapping example please see page 33.




R Point(R.25) When G99 is used 'Z' will return to the R point.


31

Fine Boring (G76)

Example

G98 G76 X0.0 Y0.0 Z-1.5 R.25 Q.005 F10.

Please consult your machine operation manual for correct

orientation when using a single point-boring tool.

'Q' represents the amount tool will move away from machined face before lifting out of hole.

Set the direction and axis in which you want to move away in using parameter 5101 bit 4 and 5

Initial Point (G43 Z1. H01)Tool will stop 1.0" above part. When G98 is used 'Z' will

return to the Initial point.


R Point(R.25)'Z' - Zero is top of part.


Spindle stops. Moves .005" away from part. Rapids out.

Rigid Tapping (G84)

Example (1/2-13 Tap)

G0 G90 G54 X0 Y0

G43 H01 Z.25 M8

G95 S1000 (G95 feed per rotation)

M29 (Rigid tapping mode) G98 G84 Z-1.5 R.25 F.0769 (Tapping cycle with 'F' = pitch of thread) G80 M9

G94 (Feed per minute) G91 G28 Z0 M5

G90

M30

Important thing to

remember when Rigid Tapping

the feedrate must be the pitch of the thread.

When rigid tapping it is possible to retract the tap up to 200% faster than the programmed feedrate. This is achieved by changing the following parameters: Parameter 5200 bit 4 (DOV) to 1

Parameter 5211 enter amount 1% - 200%

The only limitation is that once the parameter is changed it will be the same for every tap.




R Point(R.25) When G99 is used 'Z' will return to the R point.


33

Rigid Tapping Using an Alternate Axis

It is possible to rigid tap using an axis other than Z. This is often used when the use of a right angled head is necessary.

Parameters. Before starting set the following parameter. 5101 bit 0 to 1 (FXY)

If an axis other than Z is required to apply the 'H' value (Tool Length Offset G43) then set the following parameter.

5001.1 bit 1 to 1 (TLB)

Make sure that the program contains the correct reference plane selection. G18 X and Z

G19 Y and Z

The following example will tap 4 holes using the Y axis

N10 G0 G19 G54 G90 X0. X0. N20 G43 Y.5 H01

N30 G95 S1000

N40 M29

N60 X-3.25 Z-.75

N70 X-.75

N80 Z-3.25

N90 G80 N100 G94

When finished remember to return parameters back to their original settings

34

Repetition of Canned Cycles (K)

By placing an 'K' on the same line as the canned cycle command it is possible to repeat the cycle.

The 'K' command should only be used with G91(incremental). If G90 (absolute) were to be used only the 1st hole would be machined.

Example 2

G0 G90 X0 Y0 (1st hole position)

G91 G98 G81 X0.50 Y0.50 Z-1.R.25 K3 F20.

G90

Example

G0 G90 X0 Y0 (1st hole position)

G91 G98 G81 X0.50 Y0.0 Z-1.R.25 K6 F20. G90

35

Use of 'K0' in Canned Cycles

Placing a 'K0' at the end of a canned cycle will prevent the cycle from being executed at that position.

This allows the operator to have all the hole positions in a subprogram and define canned cycles in the main program.

Program Numbers

Technically the numbers O0000 through O9999 are available for creating program numbers. However some numbers are used by other functions and

are best avoided when creating a program.

To prevent accidental editing or deletion of programs, turn program protect key to lock and remove the key.

O9000 through O9999. These numbers are used for Macro programs and for 'Tool change' and 'Pallet change' programs. It is possible to call these programs using a 'G' or 'M' code by setting parameters.

O9000 program numbers are protected. To unprotect them change parameter 3202 bit 4

(NE9) to 0.

O0001 through O7999

These numbers are generally used for 'G' code programs and can not be protected by parameters.

O8000 program numbers can be protected by changing parameter

3202 bit 0(NE8) to 1.

O8000 through O8999

These numbers are also used for Macro programs and can also be protected against accidental editing and deletion by setting a parameter.

Editing a Program

The following is the procedure for Inserting, Altering and Deleting a command in a program which is registered in the controls memory.

Using the cursor keys highlight the command to

be changed.

Press the PROG hard key and make sure that the program requiring editing is displayed.

Alter Example N20 G1 X3.265 Y-2.987 F30. Key in new value (Y-2.950)

Pressing the Alter key will change Y-2.987 to the new value

N20 G1 X3.265 Y-2.950 F30.

Delete Example N20 G1 X3.265 Y-2.987 F30. Pressing the Delete key will remove Y-2.987

N20 G1 X3.265 F30.

Insert Example N20 G1 X3.265 Y-2.987 F30. Key in new value (Z-1.250)

Pressing the Insert key will insert the new value after Y-2.987

N20 G1 X3.265 Y-2.987 Z-1.250 F30.

Once the command is highlighted it is possible to change it. If the command is no longer needed simply press the Delete key to erase it. If the value needs to be changed simply key in the new value and press Alter. If a command has to be added, highlight the command before the point were the new data is to be inserted, key in the new command and press Insert.

M1

/

Optional Program Stop. This M-code stops the machine in the same manner as program stop (M0) except the operator must turn on the Optional stop switch anytime prior to the M1 being read. If the Optional stop switch is not turned on then the M1 command is ig-

To continue operation after an M0 or M1 press cycle start.

To turn ON the switch must be in the UP position.

Optional Block Delete. It is possible to skip a line or lines of information without having to delete them from the program. By placing a forward slash (/) at the beginning of a line and by turning on the block delete switch the control will ignore these lines. Example. N10 G0 G90 G54 X2.00 Y2.00

/ N20 S4000 M3

N30 G1X-4.00 F20. With block delete turned ON the program will move from line N10 to N30 ignoring N20. With block delete turned OFF all lines of information are read.

PCMCIA Card (Memory Card)

Daewoo Machining Centers using the i series controls (not including the 0i) now have the ability to read from a PCMCIA card. This is a memory card and is used in the same way as you would use a 31/2”

floppy. With the cards you can upload and download programs and it is also possible to DNC directly from the card. This option makes the RS232c somewhat redundant as the PCMCIA card is much faster

than the RS232c hook up. A program run from the card takes the same run time as a program that is stored in the controls memory. It is also possible to search through and restart anywhere in a program as

long as the program contains line numbers. Most laptop computers already come with the PCMCIA card drive installed otherwise a suitable drive must be purchased. The easiest way to do this is to buy a stand-alone unit, which plugs in to the computer USB port.

The PCMCIA cards and stand alone reader/writers are available from most computer stores (CompUSA, EGGHEAD, etc.)

And also several sites on the internet.

When using the PCMCIA card you must first set the

Coordinate System Rotation

By using this option it is possible to rotate a programmed shape. G68 is used to turn on Coordinate System Rotation, along with 'X' & 'Y' position

which is the center of rotation and 'R' which is the angle of rotation.

To use Coordinate System Rotation the program format should look like this: P1066 M98 - - -- - - Main program containing all information to machine part. G68 X0 Y0 R45. - - Rotates part 45 degrees with X & Y zero being center of rotation. P1066 M98- - - - - - -Call main program and machine rotated part.

Tool Life Management

Tool Life Management gives the operator the ability to change a worn tool to another tool during program run without stopping the machine. Tools are classified into

groups and a tool life is set for each group in either number of times used or length of time. When a tool exceeds the preset number of times used or time set, then the next tool in that group is selected. Once all tools are used then an alarm is generated to let

the operator know that the tools must be changed.

Setting Z

Work Offset Value

Using an indicator measure the distance from the face you touched your tools off to the face of the next part to be machined. Enter this amount (A) in your work offset Z value you have assigned for that

part. eg. G55

Bore Mill Machining Example

Set up and use of the horizontal boring mill is very similar to a standard horizontal machining center. The major difference is that the boring mill has a 'W' axis.

The 'W' axis is a quill and can only be used for positioning.

When the 'W' axis is at its home position (G91G28 W0), enter this position into the work offset number you will be using. E.g. G54 W 27.890

Then when you call your work offset all moves will be read as zero from this position.

The following is an example of a peck drilling cycle.

G80G49G40G0

G91G28Z0W0 T1 M6 (Calls Tool 1)

G90G54X9.0Y25.0W-5.0S700M03 (Moves to X, Y and 'W' position)

G80 Z2. (Cancel pecking cycle)

M69 (Unclamp W axis)

G91 G28 Y0. Z0. W0. (Sends Y, Z and W axis to home position)

G90

M30

Always clamp the 'W' axis before machining.

M68 - Clamp

M69 - Unclamp

Machine's built after 2003 now do the clamp/

unclamp automatically so it is not necessary to

use M68 and M69.

83

Macro Programming

Fanuc controls have an option feature known as custom Macro. This is powerful program language that allows programs to be written using variables instead of

fixed numbers.

There are several ways to call a Macro program. 1. Using G65 followed by the Macro program number. e.g. G65 P9010

2. Using a custom G-code. G100 variables are set in parameters 6050 - 6059

3. Using an M code. M-code variables are set in parameters 6071 - 6079.

6050 G Code to call Macro program 9010










By putting 100 in parameter 6050 every time G100 is

placed in the program Macro 9010 will be called.

6071 M Code to call Macro program 9001









By putting 100 in parameter 6071 every time M100 is placed in the

program Macro 9001 will be called.

Milling Formulas

The following formulas are used to calculate speed and feeds, metal removal rate, surface feet per minute and horse power used.

Symbols and Measurement Units

D = diameter of milling cutter (inches)

d = depth of cut (inches)

F = feed rate (inches per minute)

f = feed (inches per tooth)

K = power constant of work material E = spindle efficiency (varies from 75% to 90%)

W = width cut (inches)

Z = number of teofeth in the cutter

mrr = metal removal rate ( cubic in/min)

HPc = horse power at the cutter

sfm = surface feet per minute

To calculate Surface Feet per Minute (SFM) sfm = .262 x D x rpm To calculate Feed rate (inches per minute) F = f x Z x rpm To calculate Feed (inches per tooth) f = F/Z x rpm To calculate Metal Removal rate (mrr) mrr = W x d x F To calculate Horse Power at the cutter (HPc) HPc = mrr/K

Example: To find the Surface Feet per Minute (smf) of a 3/4" 4

Side Mounted Tool Changer Recover

This is the procedure for recovering a side mounted tool changer should the machine loose power or if the tool is inadvertently load wrong.

1. Restore Power (It is not necessary to Zero return the machine)

2. On the Automatic Tool Changer (ATC) box at the back of machine, set switch to

manual. 3. In MDI key in M39; and press the start button. (This starts maintenance mode and allows you to use the 2 keys for rotating the tool magazine as jog keys for the tool changing arm.) 4. Turn mode switch to JOG

If you have a tool in the spindle make sure that the tool is unclamped (Green light on). If not, manually press tool unclamp button. 5. Using the jog keys (on the ATC box) move the tool changer arm to home position (you will have to press the key several times). Carefully watch the tool that is being placed in the spindle. Once it is in position in the spindle manually press tool clamp before proceeding otherwise the tool will drop. Finish pressing the jog key until the arm is at home position. 6. Turn mode switch to MDI

7. In MDI key in M19; and press the start button (spindle orientation)

8. Key in M41 (will complete 1 complete tool change)

9. Set APC box back to Auto. 10. Check to make sure that you have the correct tool number in spindle before continuing. To display tool register

Press SYSTEM ? PMC ? PMCPRM ? DATA ? G.DATA Page to show parameters D450 & D452

During a normal tool change

(1) Next tool is placed in spindle. (2) Tool from spindle is returned to waiting pot. (3) Tool is returned to correct pocket in magazine. After this the next tool called is brought to the waiting pot position, then the magazine rotates back so that the pocket number and the tool in the spindle are the same. At all times the magazine should have (2) empty spaces.

Occasionally due to tool changing errors (2) pots will be in the waiting pot position. For this example we have T5 in the spindle and T10 as the waiting tool. The Pot position's were the spindle tool and waiting tool came from should be empty (e.g. P5/P10). Look in the magazine to see were the third pot is missing from (e.g. P20). Manually rotate the magazine so that the third empty pocket and the misplaced pot are in line. On the CRT press Hard Key - SYSTEM, (soft keys) - PMC - PMCPRM - DATA - G.DATA. This will display the following. N0 ADDRESS DATA

0000 D0450 5 (This is the tool in the spindle)

0001 DO452 10 (This is the tool in the waiting pot) Change D0452 to matched the third empty pocket number (e.g. 20). In manual bring pot over to magazine side. Change D0452 back to waiting pot number (e.g. 10). Return magazine back to auto mode. The magazine should now be back in sequence.

Heavy Tool Limitations

Before using a heavy tool you must first calculate the tools 'Moment' before

attempting a tool change. This should not exceed the machines maximum tool weight.

Weight Center

Taper Gage Line

Calculate the tools 'Moment' as follows

1. Find the tools center of gravity

2. Measure the distance from the tools center of gravity to taper gage line. 3. Weight x length = Moment

The easiest way to find the tools center of gravity is to tie a piece of string

around the tool, and then find the point at which the tool is balanced. Measure from the string to the taper gage line.

Measure from center point to taper gage line

97

Uses of Large Tool

The following method is recommended when using a large diameter tool.

Empty Pockets

Tool's with numbers 70 and higher are considered 'large Tools'. Before you start to use a large tool you must first set the 'Tool Registry'.

To access the Tool Registry see page 50

When loading a large tool make sure that the pots on either side are empty. In the 'Tool Registry' set the empty pots to "00".

In this example 'Pot 8' has the large tool with Pots 7 and 9 empty. When T70 is called in the program it will always be placed back in Pot 8.
