Dresser/Wheel Radius Compensation
Chapter 15
15-31
Selecting a dresser/wheel offset number T0000 in a program does not
cancel radius compensation and does not generate an exit move. Radius
compensation continues on as if a dresser/wheel radius had been changed
to a radius of zero. See page 15-51 on changing dresser/wheel radius. If
T0000 is the active dresser/wheel radius, the exit move is equal to the
programmed dresser/wheel path.
Important: An exit move cannot be a circular move (G02 or G03). You
must program all exit moves on a linear path. Any attempt to generate an
exit move using a circular path generates an error.
Example 15.7 shows examples of exit move program blocks.
