14. TOOL COMPENSATION FUNCTION
B–63522EN/02
NC FUNCTION
194
The tool geometry compensation function compensates the tool figure or
tool mounting position. The tool wear compensation function
compensates the wear of a tool tip. These compensation amounts (offset
values) can be set separately. There are two types of geometry
compensation: So–called geometry compensation and the second
geometry compensation that allows the user to specify whether to use the
direction directed by the PMC. The second geometry compensation is
used to compensate for the difference in tool mounting position or
selected position. If distinction between them is not necessary, the total
value of them is set as a tool position offset value.

In the system in which the Y axis is the fourth axis, the Y axis can be
compensated by the tool offset value.When the tool geometry/wear
compensation option is specified, tool geometry/ware compensation is
valid for the Y-axis offset.
NOTE
1 To use the Y-axis offset, the Y axis must be a linear axis.
2 The direct input function of tool offset value or direct input
B function of tool compensation amount measured value
cannot be used for the Y-axis offset.
