Experimental Study On Milling Force Of Milling Cr12

With the development of mechanical Manufacturing, Cutting method in the production practice has been widely used.Currently, in the cutting process and applications, milling has become one of the most widely used method of processing.The mechanism of the milling process is very complex. So far, studies on the mechanism of metal milling is also not perfect and mature.During the process of metal milling, milling force is a physical parameter of great importance. The research on the size of milling force will have the dramatically desirabe significance on understanding of the process, analysis and selecting a reasonable cutting parameter. This paper studies the size of the milling force changes during the process of milling Cr12.This experiment mainly studys the law of feed rate, spindle speed, axial depth of cut and radial depth of cut on the milling forceThe major elements of test are as follows:(1) The trend of affecting of the four factors on milling force are analyzed by means of designing the single factor experiment.(2) The rules of affecting of feed rate, spindle speed, axial depth of cut and radial depth of cut on milling force are analyzed by means of designing the orthogonal experiment of four factors and four levels. The mathematical model of milling force of milling Cr12 is set up.(3) The mathematical model o f milling force of X and Y is b uilt,The significance test of regression equation and coefficient is finished . The test shows that the milling force of maximum of X andY has an increased trend with the the axial depth of cut ,the feed rate, and radial depth of cut being increased.However, spindle speed on the impact of the milling force of maximum has opposite trend with their increase. For a given level of significance, the feed rate and axial depth of cut have greater impact on the maximum milliing force and the axial depth of cut has more small influence on the milliing force of maximum...
