The wood of China fir and Taiwan zelkova were used for cutting test. Cutting conditions of the tool were rake angle 35°, sharpness angle 29° and clearance angle 26°. Five depths of cut were laboratory fraise for metal cutting. The cutting force measurements, based on the cutting surface of the test material, were performed by a quartz piezoelectric three component dynamometer.
