On the Behaviour of Chip at Steel Cutting : Part 2, In the Case of Parallel Type Chip Breaker

Abstract

This paper describes the behaviour of chip at steel cutting by lathe tools with parallel-type chip breakers, which is a most fundamental type of chip breakers. The first half describes the curling radius of chip bent by chip breakers. We introduce here our new equation about the curling radius. The latter half describes the chip breaking action of chip breakers. Using the above equation of curling radius, we succeeded in an equational representation of the conditions, in which chip is properly broken. On the basis of this equational representation, a monograph was drawn up for the design of chip breakers.
