영문 초록

The curved surface machined by plate end mill causes a excess non-cutting volume, in these cases ball end mill is used for the curved surfaces. This study is aimed to obtain the optimum cutting condition by measuring the surface roughness on the conditions of various cutting speed, table speed, tool diameter, radius of curvature when machining the curved surface using the ball and mill. The cutting condition were the same as follow, velocity; 15, 20, 25, 30m/min, feed; 40, 60, 80, 100m/min amd radius of curvature; 30, 40, 50, 60mm, tool diameters; ∅8, ∅12, ∅16, ∅20mm. Analizing the working results, we can acquire the optimum cutting condition of curved specimen at the cutting velocity of 20∼25m/min and the feed rate of 80mm/min. As the same cutting condition, the best surface roughness was showed at ∅16mm of the tool diameter. But the tool diameter was smaller than ∅8mm, we could improve for the surface roughness by controlling the cusp.
