Offset Tables and Setup
Chapter 3
3-6
Important: In order for newly modified tool offsets to become
immediately active, cutter compensation must be off (G40 mode). If it is
on (G41/G42 mode), the control generates the error message “CHANGE
NOT MADE IN BUFFERED BLOCKS”. This indicates that the control is
still using the old offset values and must first run several program blocks
before using the new offsets values. The new offsets may then be activated
too late for your particular application.
To manually display or alter the offset tables follow the directions below:
1. Press the {OFFSET} softkey.

2. Display either the tool geometry offsets or the tool wear offsets.
To display the geometry offsets (tool length offsets and the tool
diameter data), press the
{TOOL GEOMET} softkey. An example of a
tool offset geometry screen is shown in Figure 3.3.
To display the wear offsets (tool length and diameter wear data),
press the
{TOOL WEAR} softkey. An example of a tool offset wear
screen is shown in Figure 3.4.
