Abstract:The widespread use of hard turning processes in industry has been facilitated by efficient work holding methods. In this paper, a novel application of the shoe-centerless work holding method is proposed for hard turning. Since changes in cutting forces during hard turning affect force balance, rotational instability can occur with shoe-centerless work holding. This paper describes the effect of changes in cutting forces due to tool wear on work rotational stability during shoe-centerless hard turning. It also presents guidelines to determine the optimum shoe setup angles for various hard turning process conditions to ensure work rotational stability and geometrical rounding stability.
Keywords:Hard machining  Finishing  Shoe-centerless hard turning
