Dresser/Wheel Radius Compensation
Chapter 15
15-3
Dresser/wheel radius compensation also uses dresser/wheel orientation
data. You need orientation data:
to compensate for inaccuracies that can occur from difficulties in
measuring wheel corner and dresser radius because of mounting
position
and
to tell the control which edge of the dresser/wheel you intend to use
when dressing or grinding
If the above is not a factor, make sure all orientations use an orientation of
0or9.
Enter the radius and orientation data into the offset tables before
attempting to activate any compensation. See chapter 3 for details on
entering offset table data.
Types of Dresser/Wheel Radius Compensations
Two types of dresser/wheel radius compensation are available on the
control:
type A (as described on page 15-17)
type B (as described on page 15-27)
The following table highlights the differences between the two types:
