Prediction of Cutting Temperatures in Turning Carbon Fiber Reinforced Plastics Composites with Worn Tools

Chung-Shin Chang, Je-Ee Ho, Chang-Hu Chan and Baw-Chiang Hwang

Abstract

Temperatures of the carbide tip's surface when turning Carbon Fiber Reinforced Plastics (CFRP) with a worn main cutting edge tool is investigated. The frictional forces and heat generated in the basic cutting tools are calculated by using the measured cutting forces and the theoretical cutting analysis. The heat partition factor between the tip and chip is solved by using the inverse heat transfer analysis which utilizes temperature on the carbide tip’s surface measured by infrared as the input. The carbide tip’s surface temperature is determined by Finite Element Analysis (FEA) and compared with temperatures obtained from experimental measurements. Good agreement demonstrates the proposed model.
