Wheel Length Offsets
This chapter describes how to select and activate wheel length offsets.
Some grinding applications require the use of wheel length offsets in
conjunction with dresser/wheel radius compensation. For details on
selecting and activating dresser/wheel radius compensation, see chapter 15.
This chapter covers these topics:

Modern grinders typically require the selection of multiple control points
on the wheel for grinding different contours and dressing different profiles.
Use the wheel length offset feature to shift the control point to the various
control locations on the grinding wheel.
