A Study of the Sensitivity of Parameters Affecting Coated Tool Life in High Speed Milling Superalloy GH4169
Through the orthogonal test of the TiALN coated carbide tool high-speed milling of high-temperature alloy GH4169, the empirical formula of the tool life are acquired by using multiple linear regression method. On the basis of this formula, studying the absolute sensitivity and relative sensitivity of TiALN coated carbide tool life for milling speed, depth of cut and feed; The results showed that in the process of high-speed milling of high-temperature alloy GH4169, tool life decreased with the increase of milling speed, feed and depth of cut; tool life is most sensitive to the change of milling speed; change of feed take second place and milling depth is the least sensitive.
