Modeling of the centerless infeed (plunge) grinding
2017-8-25 centerless infeed (plunge) grinding process is described. For a 3-D simulation model of form generation, contact points are assumed to be on least squares contact lines at the grinding wheel, regulating wheel, and work-rest blade. Using force and deflection analyses, the validity of this assumption is shown.

Abstract A computer simulation method for investigating the form generation mechanism in the centerless infeed (plunge) grinding process is described. For a 3-D simulation model of form generation, contact points are assumed to be on least squares contact lines at the grinding wheel, regulating wheel, and work-rest blade.

Regenerative chatter in a plunge grinding process with
2016-12-20 Grinding vibrations caused by regenerative cutting force and workpiece imbalance are discussed in this study. To regenerate workpiece surface, a grinding wheel is rotated, and pushed towards a rotating workpiece, rubbing and cutting its surface, with regenerative and frictional interactive forces generated.

2022-3-20 The table recip rocates longitudinally and feeds laterally after each stroke in traverse grinding. Plunge grinding, on the other hand, drives the wheel radially into the work piece while the grinding table travels longitudinally, as when grinding a groove. This form of grinding is mostly used for deburring and dimensioning flat- surfaced items.
