Abstract: In order to gain better roughness in surface highspeed milling, on the basis of analyzing the formation mechanism of surface roughness, the relationship between parts surface roughness and cutting parameters such as stepover, feed rate, machining inclination and main shaft speed angle was derived. The relationship spectrum between surface roughness and cutting parameters was proposed through test. Then the optimized processing parameters could be gotten from the spectrum according to the designed surface quality of parts in the manufacturing process. The study will provide a guidance in the machining process to avoid repeated trial cut, improve the production efficiency and lower the cost of product.
