NOTE

1 Direct drawing dimension programming commands are valid only during memory

operation.

2 The following G codes are not applicable to the same block as commanded by

direct input of drawing dimensions or between blocks of direct input of drawing
dimensions which define sequential figures.

(a)  G codes other than G04 in group 00
(b)  G codes other than G00, G01, and G33 in group 01
(c)  G codes in group 10 (canned cycle for drilling)
(d)  G codes in group 16 (plane selection)
(e)  G22 and G23

3 Corner R cannot be inserted into a threading block.
4 When the chamfering and corner R function is enabled (bit 2 (CCR) of parameter

No. 8134 is set to 1), both functions cannot be used simultaneously. When bit 0
(CRD) of parameter No. 3453 is set to 1, direct drawing dimension programming
is enabled. (At this time, chamfering and corner R are disabled.)

5 When the end point of the previous block is determined in the next block

according to sequential commands of direct drawing dimension programming
during single block operation, the machine does not stop in the single block stop
mode, but stop in the feed hold stop mode at the end point of the previous block.

must be specified in the block following a block in which only the angle
instruction is specified.

(Example)

N1 X_ ,A_ ,R_ ;

N2 ,A_ ;

N3 X_ Z_ ,A_ ;

In addition to the dimensional command, angle command must be specified in
block N3. If the angle command is not specified, alarm PS0056, “NO END
POINT & ANGLE IN CHF/CNR” is issued. If the coordinates are not specified
with an absolute programming, alarm PS0312, “ILLEGAL COMMAND IN
DIRECT DRAWING DIMENSIONS PROGRAMMING” is issued.

10 In the tool nose radius compensation mode, a block in which only the angle

command is specified in direct drawing dimension programming is assumed to
be a block with no move command. For details of compensation when sequential
blocks with no move command are specified, see the explanation of tool nose
radius compensation.

11 If two or more blocks with no move command are specified between sequential

commands of direct drawing dimension programming, alarm PS0312 is issued.

12 When bit 4 (CCR) of parameter No. 3405 is set to 1, address A in the G76

(multiple threading cycle) block specifies the tool nose angle.

When A or C is used as an axis name, it cannot be used in the angle or
chamfering command in direct drawing dimension programming. Use ,A_ or ,C_
(when bit 4 (CCR) of parameter No. 3405 is set to 0).

13 In a multiple repetitive canned cycle, in blocks with sequence numbers between

those specified at P and Q, a program using direct drawing dimension
programming can be used. The block with the last sequence number specified at
Q must not be an intermediate block of these specified blocks.

14 If a minus value is commanded as a chamfering value / corner R value, alarm

PS0055, “MISSING MOVE VALUE IN CHF/CNR” is issued. When bit 7 (CRC) of
parameter No. 3458 is set to 1, alarm is not issued even if a minus value is
commanded as a chamfering value / corner R value and a minus value is
converted to a plus value.

Tool Geometry Offset and Tool Wear Offset

Tool geometry offset and tool wear offset are possible to divide the tool offset to the tool geometry offset
for compensating the tool shape or tool mounting position and the tool wear offset for compensating the
tool nose wear. The tool geometry offset value and tool wear offset value can be set individually. When
these values are not distinguished from each other, the total of the values is set as the tool offset value.

NOTE

Tool geometry offset and tool wear offset are valid, when the bit 6 (NGW) of
parameter No. 8136 is 0.

Set the distance from tool nose to the point on the program ( tool nose of standard tool, or tool mounting
position ) to a tool geometry offset value.

Generally, a sign of tool wear offset value is the opposite to a sign of tool geometry offset value. In the
example of the above figure, the geometry offset value is a positive and the wear offset value is a
negative.

Tool Selection

Tool selection is made by specifying the T code corresponding to the tool number. Refer to the machine
tool builder's manual for the relationship between the tool selection number and the tool.

Offset Number

Tool offset number has two meanings. It is specifies the offset distance corresponding to the number that
is selected to begin the offset function. A tool offset number of 0 indicates that the offset amount is 0 and
the offset is cancelled.

Offset

Explanation

- Offset methods

Two methods are available to geometry offset and wear compensation, offset with tool movement and
compensation with coordinate shift. Which offset method to select can be specified with bit 2 (LWT) and
bit 4 (LGT) of parameter No. 5002. When tool geometry and wear compensation is disabled (bit 6
(NGW) of parameter No. 8136 is set to 1), offset with tool movement is assumed unconditionally.

- Offset with tool movement

The tool path is offset by the X, Y, and Z tool offset values for the programmed path. The tool offset
distance corresponding to the number specified by the T code is added to or subtracted from the end
position of each programmed block.
The vector with tool offset X, Y, and Z is called the offset vector. Offset is the same as the offset vector.

in the same block as that containing a T code, alarm PS0245, “T-CODE NOT
ALLOWED IN THIS BLOCK”, is issued.

- Offset with coordinate shift

The workpiece coordinate system is shifted by the X, Y, and Z tool offset amounts. Namely, the offset
amount corresponding to the number designated with the T code is added to or subtracted from the
absolute coordinates.

Offset operation with coordinate shift

- Starting and canceling offset by specifying a T code

Specifying a tool offset number with a T code means to select the tool offset value corresponding to it and
to start offset. Specifying 0 as a tool offset number means to cancel offset.
For offset with tool movement, whether to start or cancel the offset can be specified with bit 6 (LWN) of
parameter No. 5002. For compensation with coordinate shift, the offset is started and canceled when a T
code is specified. For the cancellation of geometry compensation, its operation can be selected with bit 5
(LGC) of parameter No. 5002.

(Note that geometry offset can be canceled only if bit 5 (LGC) of parameter No. 5002 = 1.)

- Canceling offset with reset

Tool offset is canceled under one of the following conditions:

<1>  The power to the CNC is turned off and turned back on
<2>  The reset button on the MDI unit is pressed
<3>  A reset signal is input from the machine to the CNC

In cases <2> and <3> above, it is possible to select a cancel operation using bit 3 (LVC) of parameter No.

Limitation

- Helical interpolation (G02, G03)

Tool offset cannot be specified in a block in which helical interpolation is used.

- Thread cutting (G32,G34,G35,G36)

Tool offset cannot be specified in a block in which thread cutting is specified. If tool offset is specified,
alarm PS0509, “TOOL OFFSET COMMAND IS NOT AVAILABLE”, is issued.

- Coordinate system rotation (G68.1)

Coordinate system rotation is executed on the command program first, followed by tool offset.

- 3-dimensional coordinate conversion (G68.1)

If tool offset is used, tool offset with coordinate shift cannot be used. Offset with tool movement must be
specified inside a nest of 3-dimensional coordinate conversion. At the beginning block of the
3-dimensional coordinate conversion, tool does not move for a converted tool offset value.

- Workpiece coordinate system preset (G50.3)

When the bit 7(WTC) of parameter No.1205 is 0, performing workpiece coordinate system preset causes
tool offset with tool movement to be canceled; this does not cause tool offset with coordinate shift to be
canceled.
When the bit 7(WTC) of parameter No.1205 is 1, performing workpiece coordinate system preset does
not cause neither tool position offset with tool movement nor tool position offset with coordinate shift to
be canceled.

The tool offset value is temporarily
canceled.

The tool offset value is reflected.

Coordinate shift

Coordinates with the tool offset value

parameter No. 5002 is set to 1 or bit 4 (LGT) of parameter No. 5002 is set to 0) in the coordinate system
rotation or programmable mirror image mode, alarm PS0509 is issued. The same alarm is issued when bit
6 (EVO) of parameter No. 5001 is set to 1 and the offset amount is changed.

Auxiliary function output in moving axis (G50.9)

The alarm PS5330, “G50.9 FORMAT ERROR” is issued when a T-code and auxiliary function output in

Y-Axis Offset

Overview

When the Y axis, one of the basic three axes, is used with a lathe system, this function performs Y axis
offset.
If the tool geometry and wear offset options are valid (the bit 6 (NGW) of parameter No. 8136 is 0), the
both tool geometry offset and tool wear offset are effective to Y-axis offset.

NOTE

When bit 1 (YOF) of parameter No.8132 is 1, this function can be used.

Explanation

Y axis offset results in the same operation as tool offset. For an explanation of the operation, related
parameters, and the like, refer to the item “Tool Offset.”

5.1.6.1

Support of arbitrary axes for Y axis offset

Overview

In a lath system, Y axis offset has been usable with the basic three axes only. This function enables Y axis
offset to be used with arbitrary axes other than the Y axis, which is one of the basic three axes.

5.1.7

2nd Geometry Tool Offset

Overview

To compensate for a difference in tool attachment position or selection position, this function adds second
geometry tool offset to the X axis, Y axis, and Z axis with all paths.
In contrast to this offset, the ordinary tool geometry offset is called the first geometry tool offset.
It is possible to apply a tool offset value (tool wear offset + tool geometry offset) in the reverse direction,
using an appropriate signal.
This function may be used if the offset value differs even with a single tool for a mechanical reason
depending on the mounting position (inside/outside) or the selected position (right/left).

NOTE

1 This function is an optional function.

To use this function, this option and "Tool geometry offset and Tool wear offset"
are required. "Tool geometry offset and Tool wear offset" can be used, when bit
6 (NGW) of parameter No.8136 is 0.

2 When the "Y-axis offset" is enabled (bit 1 (YOF) of parameter No.8132 is 1), the

"2nd Geometry tool offset" for Y axis can be used.

Explanation

- Specification method

Offset using the second geometry tool offset is performed with a program command.
Specify the second geometry tool offset with a T code command, and using the second geometry tool
offset signal G2SLC, specify whether to set the offset value of the specified tool geometry offset number
to the first geometry tool offset only or to the first geometry tool offset plus the second geometry tool
offset. If using the first geometry tool offset plus the second geometry tool offset, specify the axis to
which the second geometry tool offset is to be applied, using the appropriate one of the second geometry
tool offset axis select signal G2X, G2Z, and G2Y.

Generally, before a T code command, specify the M code to enable the second geometry tool offset. For
details, refer to the manual supplied by the machine tool builder. The same number as the first geometry
tool offset number is always selected as the second geometry tool offset number.
During execution, the tool offset value for each axis is either of the following:

•

First geometry tool offset value + tool wear offset value

•

First geometry tool offset value + second geometry tool offset value + tool wear offset value

Example)

•

The code is a 4-digit code. (The number of digits of a T code is specified with parameter No. 3032.)

•

The offset type is tool movement (bit 4 (LGT) of parameter No. 5002 = 1).

•

The lower two digits of the T code is the tool geometry offset number (parameter No. 5028 = 2).

•

Offset is performed when the T code block is executed (bit 6 (LWM) of parameter No. 5002 = 0).

•

The X axis data for first geometry tool offset number 1 is 1.000.

•

The X axis data for second geometry tool offset number 1 is 10.000.

•

The tool geometry offset number is specified with the tool selection number (bit 1 (LGN) of
parameter No. 5002 = 1).

•

Signals G2SLC = '1', G2X = '1', and G2Z = G2Y = '0'

If T0102 is specified under the above conditions, the upper two digits 01 of the T code cause the first
and second geometry tool offset numbers 1 to be selected, so that the absolute and machine
coordinates will be 11.000 on the X axis only.

- Offset data

The data for the second geometry tool offset can be set for each path. The number of items of the data can
be set with parameter No. 5024. The data remains stored even after the power is turned off.
If the data is to be made common to paths, use the common memory between each path.

4th/5th Axis Offset

Overview

This function enables tool offset for the 4th axis and 5th axis following the basic three axes (X, Y, and Z
axes). As with tool offsets based on the basic three axes (X, Y, and Z axes), 128 sets of 4th/5th axis tool
offsets are available. By setting bit 6(NGW) of parameter No.8136 to 0, tool geometry offset and tool
wear offset are enabled. Moreover, the number of sets can be increased from 128 to 200 by specifying an
option.
A tool offset value can be applied to arbitrary axes by setting an axis number (1 to the maximum number
of controlled axes) to be used for 4th axis offset in parameter No. 5044 and setting an axis number (1 to
the maximum number of controlled axes) to be used for 5th axis offset in parameter No. 5045. By setting
bit 1 (NO5) of parameter No. 11400 to 1, 5th axis offset is enabled.
If the same axis as used with the Y axis offset function is specified, however, a Y axis offset value is
applied to the specified axis, and a 4th axis offset value or 5th axis offset value is invalidated.
Tool offset values can be input through an I/O device.

NOTE

This function is an optional function.

Explanation

The operation of 4th/5th axis offset is the same as the operation of tool offset. For the operation, see
Section 5.1, "TOOL OFFSET".

Setting of tool offset values with the G10 command

By programming, 4th/5th axis offset values can be input.

or
G10 P_ U_ V_ W_ C_ Q_ E_ F_;

P : Offset number

: Specifies a workpiece coordinate system shift value.

1 to 200

: Specifies a tool wear offset value.

10000+(1 to 200) : Specifies a tool geometry offset value, with a number (1 to 200)

representing an offset number.

X  : X axis offset value (absolute)
Y  : Y axis offset value (absolute)
Z  : Z axis offset value (absolute)
U  : X axis offset value (incremental)
V  : Y axis offset value (incremental)
W : Z axis offset value (incremental)
R  : Tool nose radius compensation value (absolute)
C  : Tool nose radius compensation value (incremental)
Q  : Virtual tool nose number
E  : 4th axis offset value (absolute)
F  : 5th axis offset value (absolute)

- Explanation

As in the G10 format above, address E for inputting a 4th axis offset value and address F for inputting a
5th axis offset value allow absolute values only to be input.

NOTE

1 When compared with the conventional G10 format for changing tool offset

values, address E for specifying a 4th axis offset value and address F for
specifying a 5th axis offset value are newly added in the format above.

2 When a program based on the G10 format above is executed, only those offset

values that correspond to programmed axis addresses and offset numbers are
rewritten.

- Address name changing of format

When bit 2 (OFS) of parameter No.11403 is set to 1, the specification address in "Y-axis offset and
4th/5th axis offset" can use address name 'A' or 'B' instead of default specification addresses 'Y', 'E' and
'F'.

Example) When parameters are set to follow, the command address 'A' and 'B' are used for setting of a

tool offset.
-

Parameter No.5044 is set to 4 (4th axis offset is the 4th axis)

Parameter No.5045 is set to 5 (5th

axis offset is the 5th axis)

Parameter No.1020 (4th

axis ,5th

axis) = 65, 66 (Address name of 4th /5th

axis offset is 'A' and

'B')

Bit 2 (OFN) of No.11403 is set to 1 (Address depend on parameter No.1020)

%

A_ :

Tool compensation data (4th axis offset value in the example).

B_ :

Tool compensation data (5th axis offset value in the example).

The other addresses are the same as for the tool compensation amount.

NOTE

1 The axis name that can be used as a specification address is only 'A', and 'B'.

If specification address 'A' or 'B' is used, the address 'V' (incremental command
of Y-axis offset) cannot be used.

2 If the either of following is set, the default specification addresses 'Y', 'E', and 'F'

are used.
- Parameter No.1020 is set to axis name other than 'A(65)' or 'B(66)'.
- An extended axis name is used.

3 When bit 2 (OFN) of parameter No.11403 is set to 1, conventional offset data

cannot be read. If conventional offset data is read, set 0 to bit 2 (OFN) of
parameter No.11403.

Limitation

1.  This function is a software option.
2.  This function supports the common memory between each path.
3.  This function does not support direct input/counter input of tool offset values.
4.  This function does not support offset value writing using a custom macro variable.
5.  This function does not support the PMC window function.

However, this function supports writing/reading of 4th/5th axis offset values to and from the C
Language Executor.

6. This function does not support external data input. So, no 4th/5th axis offset value can be modified

with a PMC ladder.

7.  This function does not support the second geometry tool offset function.
8.  This function does not support the tool management function.
9.  This function does not support the wrong operation prevention function.
