Influence of Milling Parameters on Milling Performance of 300M Ultra High Strength Steel

The influence of cutting parameters (cutting speed v, feed per tooth f_z, cutting depth a_p and cutting width a_e) on cutting force and cutting temperature is analysed by orthogonal test method, and the prediction model of cutting force and cutting temperature is established. The results show that the cutting force decreases with the increase of cutting speed, but the cutting force increases with the increase of feed per tooth and cutting width, and cutting force increases with the increase of cutting depth, and the effect of cutting depth on cutting force is most significant. The cutting temperature increases with the increase of the four cutting parameters, and the effect of cutting width on cutting temperature is most significant. The prediction model of cutting force and cutting temperature can provide reference for choosing cutting parameters in actual machining. (paper)
