Nine kinds of chamfered main cutting edge carbide tools were used in turning of high-strength glass-fiber-reinforced plastics (GFRP) materials to study the temperature of tip's surface and the cutting forces. Force data from these tests were used to estimate the empirical constants of the mechanical model and verify its prediction capabilities. The friction forces and frictional heat generated on elementary cutting tools are calculated by using the measured cutting forces and the oblique cutting analysis. The heat partition factors between the tip and chip are solved by using the inverse heat transfer analysis, which utilizes temperature on the carbide tip’s surface measured by infrared as the input. The tip’s surface temperature of the carbide is solved by finite element analysis (FEA) and compared with those obtained from experimental measurements. A good agreement demonstrates the accuracy of the proposed model.
