Research on the Machining Error Control and Simulation of the Motor Frame in Vertical Lathe Machining

It's commonly existed in electric machine industry that the coaxiality of processing the rabbets of two ends of the motor frame is hard to guarantee, which is studied in this paper. An analysis of the causes of the coaxiality error of the rabbets of two ends of the motor frame in vertical lathe machining is made and strategies are proposed to improve the machining precision of the motor frame. Based on mode analysis of the motor frame in vertical lathe machining by ANSYS finite element software, the reasonable clamping method is determined and new process plan and technological equipment are designed for machining of the motor frame. The research would demonstrate great significance in improving the performance of the motor, prolonging the service life and reducing the production cost.
