摘要
提出了一种利用PC机对普通磨床进行数控改造的方案 ,并设计了基于PC的控制系统 ,该系统利用PC机控制交流异步电机实现对普通磨床进给机构进给量的控制 ,并且采用自学习控制原理和变速度、变加速度位移指令生成方法 ,因此可使磨削加工实现快速进给 ,慢速切入 ,从而减小了目标点处惯性对加工精度的影响· 该系统可实现一般精度要求零件的自动磨削加工·
An approach of improving general grinding machine by computer was presented and the PC based control system was designed. The system uses computer to control the feeding displacement of the grinding machine driven by AC asynchronous motor, and adopts the self studying control principle and the generating way of the displacement commands of varying velocity and acceleration;Thus it can realize the fast moving and slowly feeding in grinding process and reduce the inertia influence on processing precision at the destination. This system can be used to machine the work piece with general precision automatically.
