Improvement of scroll compressors for domestic air conditioners has been in progress. Scroll compressors have advantageous characteristics such as high efficiency, low vibration, and low noise.Reduci ng the surface roughness of the compressor component enables to increase the efficiency of air conditioners by means of decreasing energy loss caused by friction. However, reducing surface roughness in end face machining of endmill operation causes the problem that makes the machining time longer. The aim of this study is satisfying both high machining efficiency and good surface roughness. The sintered carbide tool produces smooth surface at higher cutting speed, but the tool suffers large wear. The CBN tool is better for high speed machining, while the large wear at the corner of the cutting edges still remains as a problem. Our present work focused on the sintered carbide tools employing high feed rate instead of high cutting speed. The factors of the tool geometry that are the width of land, the face angle, the lake angle and the number of teeth were optimized for high feed rate machining. As a result of this study, the machining efficiency increased four times and the tool life was doubled.
