Study of chip breaker on turning of stainless steel

Abstract

Machining of metals is the most universal and major stage of manufacturing system. It involves forcing of the cutting tool through the excess material of the work-piece, thereby rendering work-piece to a desired shape and size. So in present modern technology processes, optimization of machining parameters is one of the key necessities. For the case of turning operation, unbroken chips pose a major obstacle for maintaining accurate machining processes. The continuous chip generated during turning operation deteriorates the work-piece precision and causes safety hazards for the operator. Effective chip control is necessary for automatic production system because any failure in chip control can cause the lowering in productivity and the worsening in operation due to frequent stop. Chip control in turning is difficult in the case of stainless steel because chips are continuous. So the development of a chip breaker for stainless steel is an important topic for the automation of turning operations. In this study, the role of different parameters like speed, feed and depth of cut are studied.
