Investigation of cutting temperature and chip formation during rotational turning by multifaceted cutters

Abstract

The influences of conditions of rotational turning by multifaceted cutters (RTMC) on the cutting point temperature under the intermittent cutting operation are examined. By employing a different geometry of the tool and selecting an appropriate tool peripheral speed so as to reduce the tool-workpiece contact time and frictions, tool temperatures and failures are suppressed. The morphology of the different types of chips generated during RTMC confirms the theoretical position of the intense fragmentation and removal of chips from the cutting zone.
