In this chapter, we cover general information about dressing with the
in-process dresser (IPD) feature. The in-process dresser lets the control
perform a continuous dressing operation while the control is “in process”
of grinding a part.

While this dressing is taking place, the grinding wheel shrinks in diameter.
The in-process dresser takes into consideration this change in wheel
diameter and offsets the wheel position accordingly. This prevents the
grinding wheel from losing contact with the part it is grinding as its
diameter shrinks.

Important: Because of this feature’s close interaction with the wheel
length offset and dresser/wheel radius compensation features, we
recommend that you familiarize yourself with the operation of these
features before proceeding with this section. See chapters 3 and 13 for
details on wheel length offsets, and chapters 3 and 15 for details on
dresser/wheel radius compensation.

Machine Requirements

Use this feature with a roll or crush dresser. The dressing tool must be able
to move independently of wheel motion and in a direction perpendicular to
the grinding wheel center line. The dressing axis positions the dresser
perpendicular to the grinding wheel center line. Control over the rotation
of the roll or crush dresser is determined by your system installer through
PAL programming. See the documentation provided by your system
installer for details.
