AN INVESTIGATION OF TEMPERATURE DISTRIBUTION OF A CVD COATED TURNING TOOL

Abstract

The manufacturing industries experience a technological advances and development which requires high speed machining at less time. The high speed machining of the hard to machine materials put the limitation to the cutting speed and generates a lot of heat during machining which causes the tool to fail due to plastic deformation, change in mechanical properties or fracture failure of the tool. Temperature at the cutting point of the tool is a crucial parameter in control of the machining process. Due to advancement in the machine processes, a special attention has been given on the life of a tool. To achieve this, the best way is to apply the coating to the tool. In this paper, Chemical vapor deposition (CVD) coated tool is used for experimentation and the interface temperature is measured using tool work thermocouple. The nature of temperature distribution is explained using finite element analysis.
