摘　　要：介绍了研磨水晶制品的加工流程.根据加工要求,设计了水晶研磨机床的PLC控制系统,包括硬件选型设计和PLC软件设计.并提出了一种新的伺服驱动脉冲分配方法,在PLC两路脉冲源的情况下,通过分时复用,形成三路脉冲源信号,以控制三个伺服驱动器驱动各自的步进电机.实验效果证明该方法可行,并且节省了硬件开销,降低了硬件成本.The grinding processing of crystal products is described briefly in the essay.The PLC control system of crystal grinding machine is also designed according to processing requirements,including hardware design and PLC software design.And a new pulse allocation method of server driver is proposed.In order to control three servo driver to drive each step motor,three pulse source signals are formed by two pulse sources of the PLC through time-sharing,which is proved to be effective and feasible by experiment with low hardware cost.
