【Abstract】 A high-efficiency and high-precision new crank-shaft grinding method, the process-centralized method, is described. A dynamic mathematical model for the servo-system is developed, and the influences of the dynamic characteristics of a CNC servo-system on the machining accuracy of crank journals is discussed with the servo-system simplified to a first-order one. After solving the differential equation, some useful conclusions have been drawn.更多还原
