A chip-breaking system for mild steel in turning

Abstract

The reliability of machining operations is an essential requirement of modem automatic manufacturing systems. In the case of turning operations, in which unbroken chips are the major obstacles for automation, reliability implies chip control as a major aspect. Chip control in turning is difficult in the case of mild steel because chips are continuous. Thus the development of a chip breaker for mild steel is an important subject for the automation of turning operations. The presented experimental research deals with the modeling of the chip flow formation process using different insert geometrics, and leads to important characteristic parameters in chip control. This study has focused on the chip-breaker design and experimental cutting of mild steel with the chip breaker. The characteristics of chip breakage for mild steel with respect to cutting speed, depth of cut and feed were analyzed from the experimental results. (C) 1997 Elsevier Science Ltd.
