Investigation of Chip Breaker and Its Effect in Turning Operations

Chip breaker has significant role in machining process. Chip breaker and chip control in general, have long been known in continual form operations such as turning. In general machining process, chips are used to cut chips forms. Control of continuous chips in machining operation is a very significant issue to carry out productivity and operator safety. Also in particular, efficient chip control is essential for a CNC machine or automatic production system because any failure in chip control can cause the lowering in productivity. Therefore, a grooved chip breaker has been widely used for obtaining reliable discontinuous chips. In general, in order to develop a new cutting insert with a chip breaker, extensive time, research, and expense are required because several processes such as forming, sintering, grinding, and coating of products as well as different evaluation tests are necessary. A well-known method to control the chip size is utilization of chip breaker. Though, chips of highly of soft materials such as low carbon steel or thin chips created in finishing forms may not be cut simply with conventional chip breakers. Recently improvements in cutting tool technology have resulted in large number of variable chip breaker configurations. However, in most applications chip-groove design which is primary effective role, is being used try and see methodology. Special tool tips were developed and applied for chip control.
