TOOL FUNCTIONS

11.1

TOOL FUNCTIONS OF LATHE SYSTEM

Overview

When address T followed by a numeric value is specified, the code signal and strobe signal are sent to the
machine and are used to select a tool on the machine side. Just one T code can be specified in a block.
When a move command and T code are specified within the same block, these commands are executed in
one of the following two ways:
(1) The move command and tool function command are started at the same time.
(2) After the move command ends, the tool function command is started.

Explanation

A numeric value following the T code specifies selection of a tool. Part of the numeric value is also used
as a tool offset number for specifying an offset value such as a tool offset value. Tools are selected
according to the specification method and parameter setting as Table 11.1 (a):

NOTE

3032. (1 to 8 digits)

2 If 0 is set in parameter No. 5028, the length of the offset number specified in the T

code depends on the number of tool offsets.
Example: When the number of tool offsets ranges from 1 to 9:

Lowest 1 digit

When the number of tool offsets ranges from 10 to 99:

Lowest 2 digits

When the number of tool offsets ranges from 100 to 999: Lowest 3 digits

11.1.1

Tool Offset

Overview

Tool offset is used to compensate for the difference when the tool actually used differs from the imagined
tool used in programming (usually, standard tool).Tool nose moves on the programmed path by this
compensation.

Offset amount on Z axis

11.1.2

Tool Geometry Offset and Tool Wear Offset

Overview

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. When these values are not distinguished from each other, the total of the values is set as
the tool offset value.
By setting the bit 0 (WOF) of parameter No.3290, the modification of tool wear offset values or tool
position offset values by MDI key input can be disabled.
By setting the bit 1 (GOF) of parameter No.3290, the modification of tool geometry offset values by MDI
key input can be disabled. In order to permit an operator only to modify tool wear offset values, set the bit
1 (GOF) of parameter No.3290 to 1.

11. TOOL FUNCTIONS

- 1913 -

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.

11.1.3

Offset

Explanation

Compensation methods

Two methods are available to geometry compensation and wear compensation, compensation with tool
movement and compensation with coordinate shift. Which compensation method to select can be
specified with bits 2 (LWT) and 4 (LGT) of parameter No. 5002. When the tool geometry/wear
compensation is not enabled (bit 6 (NGW) of parameter No. 8136 is set to 1), however, compensation
with tool movement is assumed unconditionally.

Compensation 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. Compensation is the same as the offset
vector.

contains the offset command
