Comparative Study on Force in Milling T10 Hardened Steel with Different Machining Parameters
To compare the effects of different machining parameters on force in milling T10 hardened steel, the features of theoretical forces in up and down milling were analysised, and comparative experiments of milling force were made, whose results showed that the maximum component force in down and up milling was in the direction of radial cutting depth and feed respectively, moreover the maximum force in down milling was significantly greater than in up milling. Further orthogonal experiments of up milling and variance analysis were done, and it was found that the effects of rake angle, velocity, feed, axial cutting depth on milling force were significant at levels of α=0.05~0.0025. This study indicates that selecting milling parameters of up milling, high speed, low feed and axial cutting depth be better. This conclusion can be used as reference in designing milling scheme.
