【 摘 要 】

This study aims to determine the cutting force characteristics when cutting composite workpieces material. Cutting force is one of the cutting conditions that can determine the machinability of the workpiece. Composites have different mechanical properties from metals thus the machinability characteristics of composites will also be different compared to metals. In this research, cutting force of two GFRP workpieces consisting of chopped strand mat and woven roving type glass fibers with resin matrix was measured using a dynamometer and recorded using DAQ then the surface quality of the workpieces was analyzed. The cutting force and surface roughness characteristics are then compared to the cutting force of Perspex and Aluminium workpieces. The results show that the average cutting force measurement (Ftm) of GFRP Chopped strand mat, GFRP woven roving, Aluminium, and Perspex were 146.8845 N, 103.3915 N, 97.6002 N and 65.33 N resulting in surface roughness of 3.8511 μm, 5.2733 μm, 6.127 μm, and 6.23 μm respectively.
