Experiments have been performed by many researchers on the effects of cutting velocity on the process of wood machining, and it is known that these results differ from each other according to the kind of wood-working machines used, in the experiments. For instance, some results show practically no effect on cutting force, whereas others show a curve with a minimum value of cutting force at some velocities, or a gradual decrease with an increase in cutting velocity. In order to obtain fundamental data on the effects of cutting velocity on chip formation, cutting force and frictional coefficient, an experimental apparatus was designed for cutting tests (Fig. 1). The range of cutting velocity (V) employed in these tests were from 0.0023 to 52.53 m/sec. The depth of cut (feed of tool per revolution of a steel disk) was varied from 0.3 to 0.7 mm by varing the speed of the feed carriage in combination with two variable-speed motors and some pulleys (Fig. 1).
