Design Method for Controlling Cutter’s Consumption in High Speed Milling on Large Hardened Steel Surface

ABSTRACT

In order to solve milling cutter service characteristics conflict such as high efficiency and long life induced process domain interference problem in the process of high speed milling large-scale hardened steel surface, using variable speed and variable overhang cutting method do the vibration and wear experiments of using coated carbide milling cutter high speed milling hardened steel, obtained the wear characteristics of high speed milling cutter cutting hardened steel. Through the experiment of high speed milling cutter cutting hardened steel, characterize the impacts of milling method, diameter of milling cutter, speed, row spacing and cutting path on high speed milling cutter cutting efficiency and service life. Basis on the high speed milling cutter life and efficiency function value and the analysis and evaluation of milling cutter consumption, put forward the process design method of control tool consumption in the process of high speed milling large-scale hardened steel complex surface, conduct process verification in high speed milling machining process of automobile panel hardened steel die.
