A Study of Cutting Temperatures in Turning Carbon-Fiber-Reinforced-Plastics Materials Using Chamfered Main Cutting Edge Sharp Worn Tools

Temperatures of the carbide tip's surface when turning carbon-Fiber-Reinforced-Plastics (CFRP) materials with a sharp main cutting edge tool considered wear 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, Abaqus (TM) software) and compared with temperatures obtained from experimental measurements. Good agreement demonstrates the proposed model.
