Tool Offset Parameters
Chapter 22
22-8
Function
Use this feature to determine how the wear tool offset takes place. This
parameter determines when the work coordinate system is shifted, and
when the axis position is returned to the programmed position after the
coordinate system shifts.

immed shift -- When this parameter is set for “immed shift,” the work
coordinate system shifts when the control executes the block that activates,
deactivates, or changes the tool length value.
delay shift -- When this parameter is set for “delay shift,” the work
coordinate system does not shift until an axis motion takes place using the
axis that the tool length offset applies to. This includes the block that
activates, deactivates, or changes the tool length value.
immed move -- When the control executes a tool length offset, the position
of the cutting tool must change in the machine coordinate system and must
reflect no change in the tool position in the work coordinate system. This
requires tool motion to take place. When this parameter is set for “immed
move,” the tool moves to its offset position when the control executes the
block that activates, deactivates, or changes the tool length value.
delay move -- When the control executes a tool length offset, the position
of the cutting tool must change in the machine coordinate system and must
reflect no change in tool position in the work coordinate system. This
requires tool motion to take place. When this parameter is set for “delay
move,” the tool motion does not take place until an axis motion takes place
using the axis that the tool length offset applies to. This includes the block
that activates, deactivates, or changes the tool length value.
Refer to Figure 22.1 for a definition of the difference between shift
and move.
