【Abstract】 Aimed at the problems of complexityand difficulty to be predicted of milling force in high-speed milling, which affect the processing accuracy and power consumption, milling force model based on mechanical analysis is established, a method for identifying cutting force coefficients and instantaneous cutting force parameters is proposed, combining nominal cutting force, cutting force caused by tool eccentric runout and instantaneous average cutting force, which are three component elements of cutting force.Taking the cylindrical end milling cutter as an example, the feasibility of the identification method has been verified, which provides practical reference for accurately grasping the dynamic characteristics of high-speed milling.更多还原
