Centerless Grinding - an overview | ScienceDirect Topics

In creep feed grinding, the depth of cut can be high; in some applications it can be up to 15 mm [2]. If a good surface finish is desirable for a workpiece that is machined by creep feed, an additional operation can be done to improve the surface finish. Usually a method called sparkout is used. The sparkout method uses no depth of cut.
