5.6.2 Back spindle feed control (G43, G44)

The feed per rotation command can be specified for the back spindle.

Command format

G43 Back spindle feed per rotation OFF

G44 Back spindle feed per rotation ON

The feed rate of feed per rotation is generally determined by the main spindle speed. When the G44 is

specified for machining a workpiece at the back spindle, feed per rotation is performed at the back spindle

speed in the specified axis control group.

In general, you do not have to specify G43 and G44. When a machining pattern is switched, the

machining pattern command automatically acts as the back spindle control command.

The following table shows back spindle control for each machining pattern:

5.7.3 Last program execution (G999)

This command must be specified in the last portion (end process) of each axis control group ($1, $2, $3)

program that includes the last program.

In general, the last program is executed to perform back machining for workpieces with which front

machining is completed. The back machining is performed in the last cycle while the machine is in the

stopped state (e.g., 1-cycle stop or product counting by the counter).

Specify the G999 command for each axis control group to automatically enter the axis control groups in

the queuing state. The last program between G999 and N999 is executed in the 1-cycle or 1-block

operation mode.

Be sure to specify the N999 command at the end of the last program contents of each axis control group.

To finish program creation, specify three commands following N999 at the end of the end process. The

commands must be specified in the sequence of M02, M99 and then %.

5.7.4 Non-conform material phase adjustment (G899)

A phase shift occurs between the spindle and guide bushing and between the main spindle and back

spindle when machining non-conform materials (hexagonal material, etc). Use this command to store

the values of phase shifts in the memory of the NC unit.

Be sure to specify this command when mounting the non-conform material chuck and guide bushing.

The command is for adjustment and is not written in the program. It is used for the MDI operation.

Command format

G899 R1 K1 C1

Axis control groups

Specify this command for $1. You can execute the command in only the MDI mode.

Argument

R1: Specify this argument to store the values of phase shifts (back spindle included) in the memory of

the NC unit. The back spindle rotates when the G899 command is executed.

K1: This argument does not execute the back chuck to close.

C1: Specify this argument to phase the front C axis (C1 axis) and the back C axis (C2 axis) with each

other. The position of the front C1 axis at 0o matches the position of the back C axis at 0

o after

pick-off operation. The C1 argument must be specified with the R1 argument.

Procedure

Adjusting the phase between the main spindle and guide bushing

1. Put a material (non-conform material) through the main spindle and guide bushing.

2. Execute G899 in the MDI mode. The main spindle chucks the material and adjusts the phase.

Adjusting the phase between the main spindle and back spindle

(Phase adjustment between the front C axis and the back C axis)

1. Put a material (non-conform material) through the main spindle, guide bushing, and back spindle.

2. Execute G899R1(C1) in the MDI mode. The main and back spindles chuck the material and adjust

the phase.

M3 Programming

5-77

Notes

Specify the R1 argument whenever using the K1 argument. They must be specified in the format of

G899 R1 K1.

In a material exchange program, specify the M26 (G/B phase adjustment) command before the

command to insert a material into the guide bushing.

Specify the G814 R0, G114.1 H1 D0-2 R0 (spindle synchronization control) command before the

command to chuck the material with the main and back spindles. This will cause the phase difference

stored by G899 to be automatically added.

M3 Programming

5-78

5.7.5 Spindle synchronization control (G114.1, G814, G113, and G813) — optional

These commands control the speed and phase of a spindle in synchronous with another spindle.

Use a spindle synchronization control command when you need to synchronize two spindles with each

other. For example, use the command in the following cases: the back spindle re-chucks the workpiece

that is now chucked by the main spindle, a workpiece is machined chucked by both the main spindle and

the back spindle, and a polygonal workpiece is re-chucked by adjusting the phases of the two spindles.

The G814 command defines the main spindle (S1) as the reference spindle and the back spindle (S2) as

the synchronized spindle, and synchronizes the two spindles with each other.

The G114.1 command specifies a reference spindle and synchronized spindle, and synchronizes the two

spindles with each other.

The G113 and G813 command cancels the synchronization of two spindles that was specified by a spindle

synchronization command.

Command format

G814 R Spindle synchronization

G114.1 H1 D–2 R Spindle synchronization

G813 Spindle synchronization cancel

G113 Spindle synchronization cancel

Argument

H: Specify the reference spindle and the direction in which the spindle rotates. When (+)1 is

specified, the main spindle rotates forward.

D: Specify the spindle to be synchronized and the direction in which the spindle rotates. When

– 2 is specified, the back spindle rotates backward.

R : Specify the amount (angle) of the phase shift between synchronous spindles. The value of

R argument is added to the value that is stored by the non-conform material shift adjustment

command (G899). The R argument is valid for a clockwise shift viewed from the main

spindle. If the R argument is not specified, the value that is stored by the non-conform

material shift adjustment command (G899) is used.

Setting range: 0 to 359.999°

Notes

No phase adjustment is made if the R argument is omitted for G114.1 H1 D-2.

M3 Programming

5-79

5.7.6 Front product separation (G201)

Use this command to collect a workpiece chucked by the main spindle.

The workpiece is collected by the workpiece receiver mounted on the turret tool post, and then it is

transferred into the product receiver box.

CAUTION

For M2032 model, be sure to specify the C1 argument in the G201 command. If the C1

argument is not specified, the system does not collect workpieces.

Command format

G201 X F A T H U C1 Z R1 Front product separation

Axis control groups

Specify this command for $1.

Argument

X : Specify the X1 axis work coordinate as the end position in the cut-off process.

F : Specify the X1 axis feed rate in the cut-off process.

A : Specify the X1 axis position for end-position queuing. When the X1 axis reaches the work

coordinate specified by the A argument during cut-off machining, positioning of the

workpiece receiver of the turret tool post is completed (X2 axis product collection position).

The end-position queuing is not performed unless the A argument is specified.

T : Specify the tool number for turning the workpiece receiver. The tool number of the tool

opposite to (180o apart) the tool with the workpiece receiver mounted must be specified.

H : Specify a low speed at which the turret tool post turns. If the H argument is not specified,

the turret tool post turns at the default speed 4320 (rotation every 5 seconds).

To rotate it every 60 seconds: Specify H360 = (60 ÷ 60 seconds) × 360.


U : Specify dwell time after the workpiece receiver is positioned.

If the U argument is not specified or "0" is specified, the turret tool post (X2 axis) starts

moving backward after the X1 axis reaches to the position specified by the X argument.

M3 Programming

5-80

C1: Set the position of Z2 axis to retract point (Z2-axis machine coordinate: 4.0 mm) when

workpiece is to be collected in product chute. For M2032 model, be sure to specify the C1

argument. This argument is disabled in the machine of M1216 model.

When this argument is not specified, the Z2 axis is positioned at the forward end position.

Z : Specify the position of Z2 axis in relative to the current position when workpiece is to be

collected in product chute. When this argument is not specified, the Z2 axis is positioned at

the forward end position. The direction of Z argument (signs) is determined as minus (-) to

the left side and plus (+) to the right side when viewed from the front of the machine.

When both Z and C1 arguments are specified at the same time, Z argument precedes C1

argument.

Note: Specifying the range between Z2=0.0 and Z2=4.0 of machine coordinates will

cause an alarm because the turret cannot rotate within this range.

R1: Specify this argument to collect the workpiece, which is cut off on the front side, into the

workpiece receiver without pick-off operation. Use the R1 argument in the following

conditions: the setting switch $2$3 or $3 cycle start is disabled in the Set SW screen, the

back machining specified in the program is canceled, and only front machining is performed.

The R1 argument is useful when the diameter of the workpiece to be chucked by the back

spindle is not corrected or when you want to see only front machining. Do not specify the

R1 argument during ordinary program operation with "$1 $2 $3 cycle start enabled".

Specify the R1 argument in the G650 mode.

Argument

X : Specify the X1 (X2) axis work coordinate as the end position in the cut-off process.

F : Specify the X1 (X2) axis feed rate in the cut-off process.

A : Specify the X1 axis position for start-position queuing. When the X1 axis reaches the work

coordinate specified by the A argument during cut-off machining, the turret tool post (Z2

axis) and the back headstock (Z3 axis) start moving. If the cut-off machining is performed

with a tool on the turret tool post in the G612 mode of the G610 mode, the X2 axis is

specified for start-position queuing.

W1: Specify this argument to move the Z2 and Z3 axes to the fixed points of the G610 mode.

The turret tool post (Z2 axis) moves to the forward end position at the rapid feed rate. The

back headstock (Z3 axis) moves to the backward end position at the rapid feed rate. The

turret tool post does not move in the G612 mode of the G610 mode or unless the X2 axis is

at the return position of the turret tool post.

W2: Specify this argument to move the Z2 and Z3 axes to the fixed points of the G632 and G637

mode. The turret tool post (Z2 axis) moves to the end face of the workpiece on the back

side at the rapid feed rate. The back headstock (Z3 axis) moves to the zero point for back

machining at the rapid feed rate. The turret tool post does not move in the G612 mode of

the G610 mode or unless the X2 axis is at the return position of the turret tool post.

W3: Specify this argument to move the Z3 axis to the fixed point in the G633 and G638 mode.

The back headstock (Z3 axis) moves to the backward end position at the rapid feed rate.

I The I argument is valid only when the W argument is 2 (fixed point in the G632 and G637

mode). Specify the amount of shift from the zero point for back machining with the Z3 axis.

(Specify the I argument when the Z2 axis stroke is too short for drilling with a tool on the

turret tool post for back machining. The Z2 and Z3 axes shift the distance specified by the I

5.8.6 The turret tool post advance and retract (M40 and M41)

When the command to move the turret tool post forward (M40) is specified, the turret tool post moves its

return position (X2), and then it moves to the front machining reference point (Z2).

When the command to move the turret tool post backward (M41) is specified, the turret tool post moves

its return position (X2), and then it moves to the position 5.0 mm away from the end face of the

workpiece on the back side ("Back Spindle Chuck POS" + value specified by the I argument).

The following are examples of using the M41 and M40 commands:

In case of the next machining pattern of G610 is G630, if machining with a gang tool still continues at

completion of machining with a tool on the turret tool post of $1, execute the M41 command to move the

turret tool post toward the back spindle in advance. Conversely, in case of the next machining pattern of

G630 is G610 (G620, G640) if machining with a tool on the gang tool post still continues at completion

of machining with a tool on the turret tool post of $2, execute the M40 command to move the turret tool

post toward the main spindle in advance.

Note

If a wrong queuing ID number is specified, the operation is unable to proceed because the program

remains in the queuing state.

To queue all the three axis control groups, specify two queuing codes for the two other axis control

groups.

If the same ID number is used, either of the two other axis controls is specified with one queuing code

and the other is specified with two queuing codes. As a result, an axis control group does not queue.

In this case, the execution sequence is not simultaneous.

Queuing codes !2!3 are specified for $1 in the program sample of b. Thus, $1 queues with $2 and $3.

However, only !1 is specified for $2 and $3, so $2 and $3 do not queue. If $2 or $3 queues with $1, the

next block is executed.

As a result, the passing time of L11 is different between $2 and $3 according to the contents described

before ID number L11 in the program, and the execution sequence is not simultaneous either.

This specification may be useful for shortening operation time. However, if the contents described after

L11 in the program or the cutting conditions are changed, interference may occur. Therefore, the

specification is not recommended.

When performing secondary machining consecutively, you do not have to enter the above commands for

each secondary machining. Once the commands are entered at the beginning, they are enabled until the

overall secondary machining is completed.

Notes

The command "return to zero point for main spindle indexing" is used to maintain the same indexing

position of a workpiece during secondary machining.

If a workpiece is machined in the sequence of turning, secondary machining, turning, and then

secondary machining, this command enables the workpiece to always stop at the same position (the

angle of rotation).

S6 (tool spindle of the back 3-spindle tool post) is optional.

5.10.3 Coordinate system shift (G500 and G501)

The shift amount specific to each spindle for secondary machining is initially set. Consequently, when a

tool is set at the reference position, the program zero point does not match the tool reference point. To

match them each other, use the coordinate system shift programs (G500 and G501).

5.10.5 Back spindle C axis indexing (M48) — optional

The back spindle C axis can indexed at 0.001-degree intervals.

The back spindle C axis is turned ON when this command is executed. Zero point C0 is indexed, and

then the coordinate system is set with the position as C0.

Use a plus (+) sign to express indexing in the direction in which the back spindle rotates forward, and

define the indexing as "forward indexing". Use a minus (–) sign to express indexing in the direction in

which the back spindle rotates backward, and define the indexing as "backward indexing". When

viewed from the end face of the material, the counterclockwise rotation indicates "forward indexing" and

the clockwise rotation indicates "backward indexing".

A plus (+) sign is omitted.

Command format

M48 C Enable back spindle C-axis

Axis control groups

For the machining patterns G610, G620, and G633 in G630, specify the M48 command for $3.

For the other machining patterns, specify the command for $2.

Argument

C : Specify an indexing angle in the range –99999.999 to 99999.999°.

Note

When the M48 C command is specified, ordinary C-axis commands are enabled.

5.10.6 Circular interpolation in a secondary machining process

The circular interpolation feed is enabled on the following three planes in the secondary machining

process:

X-Y plane: G17

Z-X plane: G18 .......... Plane mode selected for ordinary turning process

Y-Z plane: G19

Generally, the Z-X plane (G18) is selected at power-on or reset. This plane is used for circular

interpolation (G02 or G03) in the turning process. To use the circular interpolation on a different plane

in the secondary machining process, execute the plane selection command G17 or G19.

Be sure to reselect the Z-X plane (G18) to return to the turning process.

Notes

Specify the machining pattern command G650 for all the axis control groups. This machining pattern

automatically enters the queuing state. Cancel the coordinate system shift command and

compensation command before executing the machining pattern command.

Execute the pick-off command (G650) after alternate machining (G610), two-saddle machining (G620),

and front/back parallel machining (G630, G635). At this time, the machining patterns of $1 and $2

are held. Since the Z3 axis moves superimposed on the Z1 axis in the G650 mode, executing the axis

move command for $3 moves the Z3 axis to the position determined by the Z1 axis workpiece

coordinates.

Position the Z1 axis at cut-off position before specifying the G650 command.

To cut off a workpiece chucked by the both spindles, execute the M24 command (backward rotation)

for the back spindle if the M03 command (forward rotation) has been executed for the main spindle.

Conversely, execute the M23 command (forward rotation) for the back spindle if the M04 command

(backward rotation) has been executed for the main spindle.

Notes

Specify the machining pattern commands G610 and G630 for all the axis control groups. These

machining patterns automatically enter the queuing state. Cancel the coordinate system shift

command and compensation command before executing the machining pattern commands.

Each axis control group should hold the feed per rotation command and feed per minute command as

modal functions.

Specify the main spindle speed command for $1. Specify the back spindle speed command for $2 or

$3.

You can create a $1 program similar to a 2-axis lathe program assuming the end face of the workpiece

on the front side to be the reference point.

Likewise, you can create $2 and $3 programs similar to a 2-axis lathe program assuming the end face of

the workpiece on the back side to be the reference point.

G630 is a modal G code that is enabled until another machining pattern command is executed.

Be sure to execute the G632 or G633 command for both $2 and $3 after executing the G630 command.

With the G632 command, specify the back machining program for $2. With the G633 command,

specify the back machining program for $3.

Tool bit wear offset numbers T41 to T80 are optional.

5.11.4 Positioning of the workpiece receiver for front/back products (M32)

Use this command to move the workpiece receiver mounted on the turret to the product collection

position.

Command format

M32 X A Z U Front and back basket positioning

Axis control groups

Specify this command for $1 or $2.

Argument

X : Specify the X2 axis work coordinate as the position of the workpiece receiver mounted on

the turret tool post. If the X argument is not specified, the workpiece receiver is moved to

the default workpiece receiver position at the rapid feed rate.

A : Specify the X1 axis position for end-position queuing. When the X1 axis reaches the

specified work coordinate during cut-off machining, positioning of the workpiece receiver of

the turret tool post is completed (X2 axis product collection position). The end-position

queuing is not performed unless the A argument is specified. When workpieces are

collected from the back spindle (the specification for $2), the A argument is invalid because

cut-off machining is not performed.

Z : Specify the Z2 axis work coordinate as the position of the workpiece receiver mounted on

the turret tool post. The axis does not move unless the Z argument is specified. The Z

argument is valid only with $2.

U : Specify dwell time after positioning of the workpiece receiver. If no U argument is

specified, the dwell time will be 0 second. The U argument is valid only with $1.

Notes

Select the tool with the workpiece receiver mounted before executing the M32 command. An alarm is

issued if the "11 Work Receiver No." specified in the machining data is not selected as the tool number

when the M32 command is executed.

If the override is changed or operation is performed with the handle in program check mode when the

M32 command is executed, the end position specified by the A argument may not match the operation.

5.11.5 Front and back product separation (M33)

Use this command to transfer workpiece from the workpiece receiver (mounted on the turret tool post)

into the product receiver box.

CAUTION

For M2032 model, be sure to specify the C1 argument in the M33 command. If the C1

argument is not specified, the system does not collect workpieces.

Command format

M33 T H U1 C1 Z

Axis control groups

Specify this command for $1 or $2.

Argument

T : Specify the tool number for turning the workpiece receiver. The tool number of the tool

opposite to (180° apart) the tool with the workpiece receiver mounted must be specified

H : Specify a low speed at which the turret tool post turns. If the H argument is not specified,

the turret tool post turns at the default speed 4320 (rotation every 5 seconds).



Modify this argument as follows.

U1: Specify this argument to collect the products in product chute to the product receiver box

using the time period that the back spindle can not receive the workpiece chucked by the

main spindle during pick-off operation. The workpiece in product chute is not collected

immediately and moves to the turret retract point. The turret rotates and collects the

workpiece while the back spindle is in pick-off operation. This is effective for shortening of

cycle time. This argument can be specified in $2 only.

C1: Set the position of Z2 axis to retract point (Z2-axis machine coordinate: 4.0 mm) when

workpiece is to be collected in product chute. Be sure to specify this argument for M2032

model. This argument is disabled in the machine of M1216 model. When this argument is

not specified, the Z2 axis is positioned at the forward end position.

Z : Specify the position of Z2 axis in relative to the current position when workpiece is to be

collected in product chute. When this argument is not specified, the Z2 axis is positioned at

the forward end position. In G732 mode (collection from the back spindle side), the

direction of Z argument (signs) is determined as plus (+) to the left side and minus (-) to the

right side when viewed from the front of the machine. When both Z and C1 arguments are

specified at the same time, Z argument precedes C1 argument.

Note: Specifying the range between Z2=0.0 and Z2=4.0 of machine coordinates will

cause an alarm because the turret cannot rotate within this range.

Notes

Select the tool with the workpiece separator mounted before executing the M33 command. An alarm

is issued if the "11 Work Receiver No." specified in the machining data is not selected as the tool

number.

To collect cut-off workpiece with the workpiece receiver mounted in the turret tool post, specify the

M33 command for $1 in the G611 mode in the G610 modes. To collect workpiece chucked by the

back spindle, specify the M33 command for $2 in the G632 mode or for $2 after the G650 command is

executed in the G632 mode.

You can use the G02 command to collect workpiece from the main spindle. However, cut-off tip may

remain on the workpiece in this case.

To collect cut-off workpiece with the workpiece receiver mounted on the turret tool post, you can also

use the command explained in <Section 5.7.6 Front product separation (G201)>.

Arguments C1 or Z is specified in workpiece separation at front side, the Z2 axis returns to the forward

end position after products are collected.

5.11.6 Sequential operation of the workpiece unloading device (M34) — optional

Use this command for the workpiece unloading device to perform sequential operation to collect the

workpiece chucked by the back spindle. Two collection methods are available: using the hand (U35J)

or the basket (U351J). Machine operation is different between the two methods.

Generally, specify this command for $2 of the machining pattern G632 and G637, and $3 of the

machining patterns G610, G620, and G633.

Argument

Hand-specific arguments

H1: If this argument is specified, operation with the hand is enabled. If it is not specified,

operation with the basket is enabled. If the H1 argument is specified, an alarm is issued

unless a check mark is put to Work Unloader B (Hand) on the Machine Structure screen. If

the H1 argument is not specified, an alarm is issued unless a check mark is put to Work

Unloader A (Basket) on the Machine Structure screen.

A : Specify the position where the hand (A4 axis) holds the workpiece. The A argument must

be specified with a negative value with the end face of the workpiece as reference. For

example, if A–20 is specified, the end face of the left claw of the hand chuck is at the

position 20 mm away from the end face of the workpiece on the back side. An alarm is

issued unless the A argument is specified.

B : Specify the amount of workpiece extraction after the hand (A4 axis) holds the workpiece.

The B argument must be specified with a positive value as the extraction from the current

hold position. For example, if B10.0 is specified, the workpiece is extracted 10 mm from

the current hold position. If the B argument is not specified, the hand moves to the queuing

position and extracts the workpiece.

Basket-specific argument

Z : Specify the position where the back spindle (Z3 axis) transfers the workpiece into the basket.

The position of the end face of the back spindle cap nut must be specified with a negative

value with the end face of the basket as reference. For example, if Z–2.0 is specified, the

back spindle is positioned 2 mm before the end face of the basket. If the Z argument is not

specified, the end face of the back spindle cap nut is positioned 5.0 mm away from the end

face of the basket.

M3 Programming

5-138

Arguments common to the hand and basket

D : Specify the position where workpieces are unloaded from the hand or basket (A4 axis)

outside the machine. The distance from the leftmost position must be specified with a

positive value. If the D argument is not specified, the hand or basket moves to the leftmost

position and unloads the workpieces.

F : Specify the feed rate (per minute) at which the basket or hand moves to the middle position.

If the F argument is not specified, the rapid feed rate is assumed.

T : Specify dwell time after workpieces are unloaded (after the hand or basket opens). If the T

argument is not specified, 0.5 second is assumed.

R1: Specifying this argument moves the hand or basket to the workpiece unloading position

outside the machine, and the operation terminates with the workpiece chucked. (Use this

argument when workpieces are to be transferred to/from another device. The hand/basket

neither opens nor returns to the queuing position.) Program commands following the M34

command are not executed until the hand or basket has moved to the workpiece unloading

position.

Knock-out-related argument specified in the M34 command

W : Specify the forward position of the product knock-out device during M34 execution. If the

W argument is not specified, the forward position in normal operation is assumed.

Notes

Executing a command T4100 to T4300 immediately after the M34 command causes interference

between the back headstock and the hand or basket that is in workpiece unloading operation. To

avoid the interference, specify the R1 argument in the M34 command or create a program using

individual M codes (see <Section 5.11.8 List of M codes for the workpiece unloading device>)

without performing sequential operation by M34.

If the hand is used to collect workpieces, Interference Check may need to be set to OFF/ON

(M88/M89). Be sure to take interference prevention measures.

Be sure to stop (M25) the back spindle before executing the M34 command.

Sequential operation by the M34 command includes opening/closing the back spindle chuck, moving

the product knock-out device forward/backward, and turning the air blower ON/OFF.

The user macro is necessary for collecting more than one workpiece by the basket when multiple work

machining is specified. When collecting a workpiece chucked by the back spindle chuck into the

basket, note that the work coordinates of X3 and Z3 axes vary depending on the selected tool number

and the value specified for the back spindle chuck position in the machining data. The above program

sample shows workpiece collection after T4300 selection with multiple work machining specified for

every 3 workpieces.

If machining is performed with T4300 while the basket is at the queuing position, it is not permitted to

put the tip of the tool into the cap nut of the back spindle.

Note

If creating a program using M35, be careful that the work coordinates of X3 and Z3 axes vary depending

5.11.8 List of M codes for the workpiece unloading device

M code Description

M34 The workpiece unloading device performs sequential operation.

M35 The workpiece unloading device moves.

M110 The hand air blower is turned ON.

M111 The hand air blower is turned OFF.

M116 The hand/basket closes.

M117 The hand/basket opens.

To create a program that performs workpiece unloading operations individually without using M34

(sequential operation by the workpiece unloading device), use commands such as M35, M110, M111,

M116, and M117 to specify the individual workpiece unloading operations.

In this case, be careful that the back headstock does not cause interference. (If the back headstock is not

at the position determined by T4000 [X3 = 0], it may interfere with the hand or basket moving.)

Use the M10 command to move the knock-out jig of the back spindle forward, and use the M11 command

to move it backward.

Command format

M10 Z F T Knock-out advance

M11 Z F Knock-out retract

Argument

Z : Specify the position to which the knock-out axis moves. If the Z argument is not specified,

the axis moves to the forward end position when the M10 command (forward knock-out) is

executed. The axis returns to the position 0 mm when the M11 command (backward

knock-out) is executed.

F : Specify the feed rate at which the knock-out axis moves. If the F argument is not specified,

the axis moves at the rapid feed rate of 15000 (mm/min).

T : This argument specifies the torque to be applied to the knock-out axis. Specify a ratio (%)

to the maximum torque. A value in the range 0 to 200% can be specified. If the T

argument is not specified, 200% is assumed. The T argument is valid only with the M10

command.

Notes

The knock-out axis does not move if the back spindle chuck is closed or the back spindle is rotating.

An alarm is issued in this case.

If the through-hole knock-out jig is equipped, place a check mark to "Knock-out jig for workpiece with

through hole" on the Machine Structure screen. Execute the M10 or M11 command to move the

knock-out jig foward or backward, respectively.

If a workpiece in which a through hole has been made is chucked by the back spindle chuck, coolant or

chips may go into the back spindle. To prevent this problem, use the through-hole knock-out jig when

machining workpieces having a through hole. To use the through-hole knock-out jig, place a check

mark to "Knock-out jig for workpiece with through hole" on the Machine Structure screen.

If the through-hole knock-out jig is provided, use the M10 command to collect machined workpieces.

Argument

Z : Specify the position to which the through-hole knock-out jig moves. If the Z argument is

not specified, the jig moves to the end face of the cap nut (0 mm).

To move the through-hole knock-out jig backward, subtract 1 or 2 mm from the length of a

workpiece into the back spindle chuck and invert the result to a negative value, then specify

the negative value as the Z argument. (This value indicates the length of the spring to be

pushed in.)

F : Specify the feed rate at which the through-hole knock-out jig moves. If the F argument is

not specified, the jig moves at the rapid feed rate (15000 mm/min).

Note

The X1 stroke is up to – 7.0. Therefore, the ordinary tool setting is unable to machine a 3.5 mm

diameter cross-drilled through-hole in a workpiece which has a 12.0 mm diameter.

If no shift amount is considered in the program, the X value is calculated as shown below.

– 12.0 – (3.5 × 0.3) × 2 = – 9.9

The X1 stroke is permitted up to X–7.0. (An alarm is issued for a stroke exceeding X–7.0.)

9.9 – 7.0 = 2.9 3.0

In consideration of leeway, the tool should be shifted 3.0 mm in diameter. Set 3.0 as "DIA" value in the

tool set data.
