We present recent advances in the modelling and simulation of Internal Traverse Grinding, a high performance grinding process incorporating a high rate of material removal combined with a high surface quality. Due to a special grinding wheel geometry, the latter two goals are achieved in just one pass of the tool through the axisymmetric workpiece.

GRINDING FEEDS AND SPEEDS - ABRASIVE ENGINEERING

In the transverse grinding process a wheel, substantially wider than the actual cross feed, distributes over its face the developed cutting force, thus permitting higher downfeed rates. The cross feed, which is used in traverse grinding only, is commonly selected to equal a specific part of the wheel width, such as 1/4 to 1/12.
