在电机制造中,许多零部件的工艺过程都涉及到工序尺寸链的解算、验算;这里我们介绍一下电机轴加工采用“后磨轴”工艺时,工序尺寸的制订及定位误差对它的影响。一、工序尺寸的制订电机轴轴伸台进行机械加工时,先后经过车、铣、磨等工序,由于铣键槽是在磨削工序之前,故铣槽深度A成为工序尺寸。下 In the motor manufacturing, many parts of the process involves the process of calculating the size chain, checking; Here we introduce the use of motor shaft machining “after grinding shaft” process, the size of the process and the positioning error of its impact . First, the size of the process of development Motor shaft shaft for machining, has passed the car, milling, grinding and other processes, because the milling keyway is in the grinding process before, so the groove depth A into the process size. under
