Designing a special cutting tool for high performance machining of CuZn40Pb2 brass alloy

Abstract

In order to be competitive in manufacturing industries, it is essential to create high performance machining processes in manufacturing plant. One of the effective ways to improve the performance of machining processes is cutting tools. Although there are various standard cutting tools, it is also possible to design a special tool to have high performance cutting by eliminating the number of steps. This study focuses on designing a new cutting tools to have high performance machining process of one of the commonly known brass alloys, CuZN40Pb2 in mass production. In this study, two teeth form brazed carbide boring tools with different geometries in terms of radial rake angle and cutting-edge radius have been utilized in order to evaluate the machining performance during boring operation of CuZn40Pb2. Edge radius of brazed carbide cutting tools varied to enhance performance of cutting tool and resulting cutting forces and surface quality of machined parts are examined carefully. It illustrated that this designed tool provides high performance cutting by controlling some design parameters including edge radius and rake angle.
