Abstract

The machined surface of cast iron changes by cutting conditions because the surface of work receives the severe plastic deformation in high-speed cutting. The purpose of this paper is to study the effects of cutting work conditions on surface roughness and friction coefficient of the cast iron (FC300). Experimental conditions were in the ranges of cutting speed 1.67-6.67m/s, feed 0.05-0.3mm/rev, rake angle -5°--35°, and the depth of cut was 0.10-0.15 mm. The experiments were carried out using CNC lath, and the friction coefficient was measured using strain gauge.<BR>Surface roughness of work was measured, after cutting experiment.<BR>The main results are follows (1) Good surface roughness was given by low feed and high cutting speed. (2) The machined surface becomes rugged at cutting speed of 1.67m/s. Good surface roughness was obtained at cutting speed of 6.67m/s, because the surface of work material caused plastic flow. (3) The best surface roughness was obtained at rake angle of -15°, and the lowest friction coefficient was obtained at rake angle of -20°. (4) The friction coefficient is high at the feed is 0.05 or 0.3mm/rev, and increases with higher cutting speed.
