B) Turret Operation

Upper Turret (A):

Turret Index Assignment:

Basic Turret Indexing:

Command only TN00 [TN000, >96 offsets]Works from either spindle mode. Positions DO NOT change in relation to spindle mode.

DO NOT use with BA=nn

Turret Angle: B-Axis Angle Range:


10/46

- 9 -

Tool Index Position: Relative to Spindle mode

BT=0 Turret Base (Horizontal) Position

BT=1 Turret vertical Position

BT=n Must be used on the same line as a TL= command

Turret Indexing Commands:

Turret Position: TN00 [TN000]

Tool Selection: TL=010101 BT=0 [TL=001001 BT=0]

There are 2 offset command structures that affect BOTH turrets

96 offsets= 01 01 01, nose radius, tool #, offset # (standard format)>96 offsets= 001 001, only tool #, offset # (no nose radius)

B-Axis Positioning:

BA: Angle

G52: Rotates the Base Tool Offset if needed (typically mill tools)

M404: Curvic clamp, valid with .001 indexMacturn clamp angle: 7.5 increments

Multus clamp angle: 15 increments

TL=0101 BT=0 BA=45.5 (G52)

[TL=001001 BT=0 BA=45.5 (G52)]

Notes:The B-Axis can only be positioned in MDI or Auto mode.B-axis position is displayed on the Actual Position display, Pages 3 & 4.

B-Axis range

Macturn: -15to +195.

Multus: -30 to +195

Tool Life Command:

To use tool life commands, replace the TL= with TG= OG=

TL=010101 BT=0 BA=45.5 G52

[TL=001001 BT=0 BA=45.5 G52]

TG=1 OG=1 BT=0 BA=45.5 G52 (same for >96 offsets)

L-Tool Indexing Function (Standard):L-Tool index function is used for lathe tools to get the proper insert orientation for the cutting tool.The standard function is M602=0 deg, M603=180 deg. relative to the M-spindle

M602-3 also controls offset selection- A or B, mill or lathe tool

This feature is only available on HSK and Capto spindles. It is NOT available with CAT or BT spindles.

TL=020202 BT=0 M603

[TL=002002 BT=0 M603]

Tool Orientation for reference only

Lathe Tool Index Function; Multi-Edge (Option):

Lathe tool function for a tool having multiple cutting edges (8 positions on Macturn/12 positions on Multus)Uses tool numbers 201-210 only, Offsets are increased to 500

The M602-3 command still identifies an opposing orientation, but there is added structure to select the primary

orientation angle for the M-spindle.Tool callouts:

Standard tooling- TL= 002002 BT=0 M602

Multi-Edge- TL= 05210210 BT=0 M602 (05 is the tool index position, 210 is the tool/offset

number)

Tool Life- TG=277 OG=1 M602 (05 is the tool index position, 210 is the tool/offset number)


12/46

- 11 -

Tool number (TG) is a calculated value ranging from 201 to 280 (8 index; Macturn) or 320 (12 index; Multus).

TG= 200 + [[tool number 201] x 8] + Edge number (Macturn formula)

TG= 200 + [[tool number 201] x 12] + Edge number (Multus formula)

Note:When a new position is commanded it becomes the new A position (M602) and the new B position

(M603) is 180 from it. This is reset by the TC= command or a tool change.

Tooling Data:Tools/offsets range from 1 to 96 (1 to 200 tools and 500 offsets optional).

A mill defined tool CAN be used as a Lathe tool, but a Lathe defined tool CANNOT be used as a Mill tool.

Ex. A drill used for side drilling can also be used with the M602/3 to lock the tool and drill on center as a lathetool with the part rotating.

Tool Management Data:

Tool Number, Tool Kind, Tool Size/Weight

Sub Mg. Tool check box - Check if tool is a main magazine tool, leave unchecked if the tool is a sub-magazine tool. (Note: There will not be a Sub Mg. Tool check box on machines not equipped with

a sub-magazine.)

Identifiers:

Tool Kind

L Lathe tool

M Mill tool

S SensorDT Dummy tool

Assigned by controlD Dummy Pot (Large Tool)

R Reserved Pot (Large Tool, See note below)

Tool Size/Weight

Standard Standard tool; Stored in ATC pot #n. Other tools can be stored in bothright and left pots (magazine #n+1 & #n-1).

B Large diameter tool left; Stored in ATC pot #n. No tool can be stored in

the left pot (magazine #n+1).BR Large diameter tool right; Stored in ATC pot #n. No tool can be stored in

the right pot (magazine #n-1).E Large diameter tool; Stored in ATC pot #n. Only standard tools can be

stored in the right and left pots (magazine #n+1 & #n-1).

H Heavy Tool; ATC arm acceleration/deceleration is reduced.

SL Super large diameter tool; Stored in ATC pot #n. No tool can be stored ineither right or left pot (magazine #n+1 or #n-1).

Note 1:When a super large, L-large or R-large diameter tool is removed from the magazine pot and mounted

in the turret, the pot where the tool was stored is recognized as a reserved pot and marked with an "R"identifier.

Note 2:When a tool is defined as a large tool of any kind the ATC arm acceleration/deceleration is reduced.

The speed of the ATC arm is unchanged.

Zero-Set:

Zero set on the upper turret should always be set from the spindle face of the turret, never from a zero-tool as istypically done on a lathe. This is so that when the turret is rotated to different angles the tool tip position can

be correctly calculated.


13/46

- 12 -

Tool Touch-off:

Even though the Macturn can have 4 sets of offsets in each spindle mode it is a simple matter to touch off each

tool through the use of Auto Calc.

Set Zero as stated above.

Place the turret in the Base A or Base B position. Select the one that makes it easier to touch off.

Select the offset page that matches the tool position. Touch off in Z and X (Z only for M-tools).

Calc the tool offset for both X and Z.

Press Auto Calc to set the correct data in all other offsets.

Note:Auto Calc should only be used when tools have been touched off with the turret in the Base or

Vertical position.

Calibration of Touch setter:

Load a qualified tool in the spindle.

Select the position (A or B) that allows the easiest access to the touch setter.

Make sure the left spindle (G140) is selected.

While in Manual Mode, select Parameters and advance the touch setter arm. The Touch setter(Sensor Position) page should be displayed.

Move the tool into position.

Using the touch setter buttons touch off the tool in X and Z.

Repeat for all four sides of the touch setter.

Note 1:In order to calibrate the touch setter it is necessary to have a properly qualified tool. This

can be obtained by touching a tool off on a part or by using a tool pre-setter. The accuracy of this

measured tool will directly affect the accuracy of the touch setter.

Note 2:To calibrate all four sides of the touch setter will require having qualified tool(s) that can

reach all four sides of the sensor head while the turret is in the Base (BT=0) position.

Note 3:The touch setter should only be calibrated in the base (horizontal) position.

Use of Touch setter:The Touch-setter makes tool setup extremely easy. Once the touch setter is calibrated:

Rotate the tool to a position that makes it easy to touch-off the tool (M602/M603).

Advance the touch setter.

Touch off M-tools in Z. Touch off L-tools in X & Z (The screen will automatically change to thecorrect turret cutting position).

All offsets will be calculated for both left and right spindles.

Note:for 45 lathe tools: When using lathe tools at an angle (typically 45) the touchsetter or Auto Calc will give someunexpected results. This is because of how Auto Calc works. When Auto Calc calculates the other offsets from the

one that was set it does so based on the distance of the tool edge back to the center point of the turret. As long as you

are touching off a tool at either the base or vertical position this is not a problem. However, when toughing tools off at

different angles (such as 45) you will get unexpected results for the opposite lathe tool index position.

Coolant/Air Control:

There are solenoids for the Upper turret coolant which are controlled by the tool kind description:A- Thru spindle coolant; Lathe tool: M08/M09, Mill tool: M174/M175.B- Flood coolant (Turret nozzles); Lathe coolant 3: M262/M263, Mill tool: M08/M09.

Both A and B can be used simultaneously

C- V-Groove coolant; Lathe tool: M263/M262, Mill tool: M08.M09.D- V-Groove airblow; All tool types: M869/M868 (with M-spindle rotation).E- Thru-spindle airblow; All tool types: M51/M50.

M08/M09 Mill tool: Coolant goes to the turret nozzles, B.

Lathe tool: Coolant goes to the lathe tool holder, A.There is a button on the control panel for manual control.

M51/M50

All tools: Thru-spindle Air Blow, use to clear coolant out of line, E.M175/M174

Mill tool: Thru-tool coolant, A.There is a button on the control panel for manual control.

M263/M262

Lathe tool: Coolant goes to the turret nozzles, B (Coolant 3) and to the V-Groove coolant, C.M869/M868

All tools: V-Groove airblow, D.

Chip Removal Cycle before ATC Operation:

(OM450/OM451/OM452: See Applications Bulletin #225 for more information and to view the programs)


15/46

- 14 -

For turning tools, drills and other equipment likely to entangle chips around the tool, the provided chip removalcycle should be used before the ATC cycle (M321 or M421).

The provided chip removal cycle takes about five seconds.

This chip removal cycle is controlled by a LIB (library) program, which permits the user to change the air blowtime and other parameters according to the workpiece material and chip condition.

For the MACTURN series type CAT and BT turning holder, which uses a tool locating pin, the removal cyclecannot be used as it requires the rotation of the M-tool spindle. If this holder is instructed to perform the removalcycle, it will result in an alarm since it is internally interlocked to prevent the rotation of the M-tool spindle.

Programs (.LIB)

OM450 - spindle air blow, periphery coolant & spindle nose air blow (w/spindle rotating)Purpose: To drain coolant from the spindle and remove chips around the tool

OM451 - Periphery coolant and spindle nose air blow (with spindle rotating)

Purpose: To remove chips around the tool

OM452 - Spindle nose air blow (with spindle rotating)Purpose: To remove chips around the tool

Lower Turret (B turret):

Notes:

The lower turret is available with M-function as an option. The lower turret may cause interference with the workholding (Main spindle; Macturn 250/350, Sub-spindle;

Macturn 550). (Ref. Appendix IV Interference Awareness Zones)

Simultaneous 4-Axis Cutting:

G/M-Codes:

G13 A-Turret select

G14 B-Turret selectG110 Constant speed cutting on turret A

G111 Constant speed cutting on turret B

G122 W-axis control, turret A designation

G123 W-axis control, turret B designation

M206 Turret Synchronous Feed Mode OFF

M207 Turret Synchronous Feed Mode ON

M200 Z-axis synchronized feeding cancel

M201 Z-axis synchronized feeding G13M202 Z-axis synchronized feeding G13

Programming Tips:

Determine the extent of operations to be performed by turrets A and B.

o The cutting times required for these two turrets should be well matched when determining thesections to be cut by each.

Determine optimum cutting conditions.o Since a spindle change cannot be performed during a simultaneous 4-axis cut, the cutting speed

will vary according to the diameter being cut. Select the insert grade carefully to suit theworkpiece material to be cut.

o Select feedrate and depth of cut by taking the cutting at the two turrets into accounto Determine the cutting conditions so that a total of the cutting power required by the two turrets

will not exceed the capacity of the machine.


16/46

- 15 -

Other considerationso The use of the INDIVIDUAL switch allows the turrets to be operated independently, facilitating

checking of trial cuts.

o Care should be taken to avoid interference: Interference between a boring bar and the chuck When performing end face cutting with the tools on turret A:

Interference between tools on turret A and a boring bar on turret B, Interference between tools on turret A and ID toolholder on turret B

o Program movements of the tools on turret B taking into account those of turret A. G02 and G03should also be programmed taking cutting with the tools on turret A into account.

o In constant speed cutting mode operation called for by G96, G110 and G111 select the turret onwhich constant cutting speed is obtained: G96 G111 calls for constant speed cutting for turret B

and G96; G110 cancels G96 G111 and selects constant speed cutting mode on turret A.

Note:This feature generates large differences in cutting speeds for the tools on turrets A and B

when, for example, performing simultaneous cutting on a workpiece with large diameter

differences. Therefore, the cutting portion handled by each turret and the cutting tip material

should be selected very carefully.

Conditions: The G code used to select the turret must always be placed at the start of a program.

Notes:

There are no differences in programming format between the programs for turrets A and B.

All commands in a program beginning with a turret selection G code are effective for the selected turret.

To program an operation for the other turret, specify the G code to select it.

Program execution proceeds in order from smaller to larger P code numbers.

S and M commands cannot be synchronized with the M100 command.

The same number of M100 codes must be used at both the G13 and the G14 sides in the program. If adifferent number of M100 codes were to be programmed in the G13 and G14 sides, operation would

continue with no waiting time.

The insertion of an M100 command into a nose R compensation operation will result in an alarm. Noadvance program reading is conducted during a stop which has been programmed by an M100 command.The nose R compensation, however, requires advance program reading, and for this reason insertion of anM100 command in this operation is not permitted.

Take special care not to mix P codes and the M100 command. Any attempt to stop one turret by use of anM100 command while the other turret is stopped due to a P code will result in operation continuing with

no waiting time at all.

Notes:

The C-axis must be engaged (M110) before any other commands can be used pertaining to C-axis or M-spindle operation with the exception of M153.

All commands pertaining to C-axis or M-spindle operation must be cancelled prior to canceling C-axismode (M109)

Use C-zero offset only for M110 (C-Axis Connect) mode. It has no effect on the M19 command. The C-zero value moves the zero position in a CCW direction when viewed from the tailstock side of the

spindle.

The C-axis coordinates increase in the CCW direction when viewed from the tailstock side of the machine.(CCW is positive/CW is negative)

Using the M19 command with a C-value rotates the C-axis in the CCW direction when viewed from theheadstock of the machine. (CCW is positive/CW is negative)

Calculating C-axis Feedrate:

To accurately calculate the correct feedrate when using the C-axis use the following formula:

500 (metric) and 19.685 (inch) are constants.

Fd: Desired linear feedrate (mm/min or in/min).

Dia: Diameter of cutting.

Metric: (Fd * 360 / (* Dia)) / 360 * 500 Inch: (Fd * 360 / (* Dia)) / 360 * 19.685

E) Y-Axis Operation

G/M-Codes:

G138/G136 Y-axis connect/disconnect

Notes:

When the Y-axis is connected the X-axis is programmed in radius.

Y-axis mode remains in effect after NC Reset and power off.

Spindle mode cannot be changed in the Y-axis control mode.

During Y-axis control mode, the Y-axis mode button lamp lights on the option panel.

When the Y-axis control mode cancel command is received (G136) the NC automatically returns theY-axis to the turning position.

Conditions:

When changing spindle modes always cancel spindle specific commands- (M110, G96, G138)

Parameters:

Optional Parameter: 1st-2ndSpindle; 2ndSpindle Zero Offset - Use this to clock the right spindle to the leftif required.

Optional Parameter: 1st-2ndSpindle; Interference free distance ZB-W (Sub-spindle) - This parameter setsthe distance allowed between the sub-spindle and the lower turret.

Notes:

There is no PD Distance on the Macturn series. To limit the approach distance, use the W-axis soft limit.This must be set for both the A and B turret.

When transferring a part between spindles and no value is placed in the C-zero offset of the 1stspindle orOp. Par.: 1st-2ndSpindle; 2ndSpindle Zero Offset, the zero point on the part should be the same on both

spindles.

If a value is placed in Op. Par.: 1st

-2nd

Spindle; 2nd

Spindle Zero Offset (assuming a left to right process),place 360 minus that parameter value in the right spindle C-zero offset to synchronize the spindle zero tothe part zero.

Part Transfer:

On sub-spindle machines parts can be transferred with both spindles running or with both spindlesstopped. If the work piece requires a specific orientation between spindles this can be maintained as well.

If no orientation is required, M210 can be used to reduce the cycle time required for pick-off.

With standard workholding, the general practice for proper chuck installation is to mount the chucks so

that the jaws are rotated 60from the opposing chuck to allow for the pick-off of short parts.

I) NC Tailstock (Multus B-300/400)The NC tailstock is a ballscrew driven, dead quill unit (Live quill optional) with a spring pack for thrust load. There isno quill travel similar to a hydraulic tailstock. Instead, the entire tailstock body moves. The tailstock is the W-Axis.

W-Zero is used and it is recommended that it be set to where the tailstock engages the part. There are 10 sizing

positions and the tailstock has tailstock confirmation built in.

Position Descriptions (see Figure 1):

Work Position: The position where the tailstock engages the part (M56). This should be the lowest of theposition settings. This position is in reference to the W-Axis Zero.

+/-OK: Tolerance for the Work Position.

Approach Position: When engaging the part the tailstock will rapid to this position and then feed to theWork Position. When retracting from the part the tailstock will feed out to this position and then rapid therest of the way. This position should be set to clear the part. This value must be greater than the Work

Position. This position is used with both the foot pedal and M55/M56. Retract Position: The clearance position for loading/unloading parts (M55). This value must be greater

than the Approach Position.

Thrust: Amount of thrust at the Work Position. High/Low thrust values are standard (M98/M99).

Conditions:

Tailstock parameter set to Center Work.

Turret at X-plus limit

Parameters:

Position data is set in values relative to a W-Zero position. On a tailstock machine the W-axis is only used for

the tailstock and has no reference to the program zero. Therefore, we recommend that W-Zero be set to theWork Position.

Work position - Where the center is engaged in part, smallest value and it is recommended that this

should match the W-Axis zero.

Approach position - rapid to position, then slow feed to work positionRetract position - clearance position to be able to remove the part, less than plus soft limit

Note:if there is a miss-match of data it will create alarm 2371 Error in TS move command.

Appendix I

General Notes: E-control and newer1. Always be sure to turn off commands or give priority to the opposing turret when leaving one spindle

to go to the other. (M110, G96, G110/G111, G94)

2. Remember that when the turrets are not working together (not 4-axis) that the commands to thespindle (M83/84, M88/89) are the same as any two axis machine. Only when in 2-spindle modewould you need to use (M248/249, M288/289)

3. Note that when making a Z-Zero Offset to the A or B-turret in G141 mode the direction of offset isreversed. Towards the spindle is a positive direction. This is because the ZA/ZB axis is on the same

ballscrew for both L/R spindles and is setup +/- to the left spindle. Also note that programming is not

affected by this. Programming towards the chuck is always a negative direction.

4. Always put the T0?0?0? (or TL=) command on a line with X- & Z-Axis commands. This holds truefor all Okuma lathes. Correct programming procedure.

5. When using C-Axis in 4-axis mode. Only one of the turrets can command M110 and the following C-axis movements. The other turret may start up and use its M-Tools but only the one that commanded

M110 can command C-positions. Then in turn only the turret that commanded M110 can command

the M109.6. Note that sometimes you will see differences when running the program in Dry Run, Machine Lock,

Individual Mode, and Single Block or any combination of these. This is because with each one ofthese conditions different Confirmations/Interlocks may be required and also, as in individual mode,only applicable parts of the program will be read.

7. Note that when using Lower turret M-Tools on the right spindle it may be required to set TurretParameter Bits in order to get the proper rotation of the M-Tool. (Please see manuals)

8. Note the following about P-Codes:

P-Codes must consecutively count up from 1. (Ex. P1, P2or P10, P25)

Usually you synchronize P-Codes (Both A/B have P10S ). You don't have to synchronize (A-Turret has P1, B has P2, A has P3)

P-? (P minus value) can be used. This will reset the P-Code count up.

Don't overuse P-Codes. It could slow your program.9. Note the following about M100:

There must be equal number of M100's for both G13/G14.

These codes act like P-Codes by holding up one turret for the other. One unique feature of M100 is that it holds the read ahead character.

Could cause restart problems if over-used.10. It is recommended that you create restart points in the program to make it easier for both setup and in

reworking or saving parts. These would typically be located before and after processes such astransfer, C-Axis work, and other complex processes. In these cases you would restart just prior to

M151, M110, M201or just after M150, M109, M200

11.Note that when performing a transfer at RPM you will need to use the M-Codes M185 and M247.M185 allows the main chuck to rotate at RPM while in the unclamp state. M247 does the same for

the opposing chuck. M184 and M246 will return them to interlock status.

12.Note that the offsets for the lower turret are common for both left and right spindles. The number inthe offset page is just added to the Z-Zero offset of the spindle mode commanded (G140/141).

13. It is recommended to establish the same spindle orientation for M19, M151 and M110. Do this forboth spindles. This will ensure that features being processed on the left spindle can easily be

identified on the right. You will need to set both parameters (LONG WORDS #40, 43,44) and

CA/CB-ZERO offsets in order to do this.

Coolant

Coolant Motor Electrical Connections

When connecting the coolant components (motors, filters, chiller, high pressure unit) care should be taken to insureproper installation. Generally, the hoses are not a problem since they are clearly labeled on both the hose and

fitting. The motors, however, are not as clearly marked and reference should be made to the electrical drawings to

make sure they are connected properly. The schematic below should work in most cases. Note that the upper turretis labeled either M2 or M2A.

Coolant Alarms:

Filter Level Float - Once the filters are full of contaminants and limiting the flow of coolant through them the

flow will exit the opening of the filter bag and down a passage to the overflow container with a float.Alarm level B: 2743

Tank Level Float - Some machines are equipped with a float on the separated portion of the coolant tank.

These alarms will notify when the level is low, but can be set to a B or C level alarm

Alarms: B-2734, C-3709

Appendix IV

Interference Awareness ZonesThe work envelope on the Macturn series machine is complicated by the size of the upper turret. This is an

attempt to bring awareness to the common interference areas.

As a recommended practice, it is desired to use the standard VDI ID base as the tallest tool in the lower turret,as it will clear in a standard machine setup. The following comments are referencing the ID base as the tallest

tool, if you have a tool that is taller, then careful attention will need to taken with your setup.

As standard the upper turret will clear the lower turret at X-zero in a horizontal position, ignoring tooling

interference.

The main areas of interference are:

1) Lower turret tooling to spindles, ID base as reference and tallest toola. Other interference if a tool is taller than ID base

2) Upper turret body to Lower turret tooling, ID base as reference and tallest tool3) Upper turret X-axis slide (Y-axis motion) to sub-spindle sheet metal

Moves with turret

At: .1

Based upon the 250/350 design, the lower turret will be parked under the left spindle when not in use or for

part transfers. Depending on the workholding on the left spindle and the tooling on the lower turret it may notbe possible to index the lower turret when it is parked under the chuck. Normally this is not a problem sincethe program will be tested out under single block mode and this condition can be avoided. The major concern

would be during a restart when the turret may index to the previous tool. To guard against this use the

following program, substituting the correct RAPA value where shown. It can also be used for the upper turret

so it does not index if too close to the chuck or spindle sheet metal.

Cycle Time Reduction

Track the timeTo check to see how long individual machine operations take save the splits to common variables as shown in the

program below. This program times how long it takes to stop and orient the spindle.

G50 S1500M3 S1500 M42

TIME=VDIN[1000]

V32=[VDIN[1000]-TIME]/1000 TIME=VDIN[1000]M5

M19

V31=[VDIN[1000]-TIME]/1000 TIME=VDIN[1000]M2

Turret one direction enableFrom the factory all Macturns are set to position the turret in the same direction every time and in 2 steps. The first

step swings the turret close to the target point but slightly to the clockwise side of the target. The second step

moves the turret counter-clockwise to the final position. This is done to maximize accuracy. To eliminate somecycle time this extra move can be turned off however accuracy will suffer. A possible compromise is to turn the

extra move off for roughing and non-critical finishing and then turn it on for critical finishing. To do this: un-check

the parameter and use M604/M605 in the program to turn it off/on. These commands are modal but are cancelled

by reset, M2, and power-off.

Note:The operator must confirm that, where this parameter is turned off, the customers required tolerances are

being maintained. B-Axis positioning accuracy is not guaranteed when this parameter is turned off.Refer to turret

parameter section for more information.

Instead of sending the turret to the X limit at the end of an operation send it to the tool change home position: G21
