NEW DEVELOPMENTS IN CHIP CONTROL RESEARCH MOVING TOWARDS CHIP BREAKABILITY PREDICTIONS FOR UNMANNED MANUFACTURE.

This paper outlines a summary of recent developments in chip control research where the authors have identified the role of chip flow direction in determining chip curl and the subsequent chip breaking. Analyses of stresses, cutting forces and chip thickness have also been made for wide ranges of cutting conditions, tool geometry and work materials when using tools with restricted contact which is considered a basic feature of grooved chip former tools. The findings of the work presented are directed towards developing a predictive model for chip breaking.
