Determination of Displacement of the Piece Center in the Process of Centerless Grinding

Abstract:

Chatter, geometric lobbing and work piece rotation problems are the main problems which affect the centerless grinding productivity. An original method was developed and implemented to determine the displacement of the centre of the piece in centerless grinding. Until now no functional tool has been developed to solve these coupled problems. In conclusion, future trends and research work in centerless grinding technology are analyzed and discussed.
