摘　　要：针对具有断续表面特征零件的磨削加工提出了在线主动测量的方法。通过在磨削加工前根据回转类零件具有断续表面的特征及磨削加工状态设定相应的参数,并将参数保存在数据库中,当测量装置的测头进出待加工零件表面凹槽时,根据凹槽在零件周向上是否周期性分布相应选择提出的断续修正法和同期特征补偿法。通过对突变的测量尺寸值进行自动的、实时的数据修正及补偿处理,从而实现对具有断续表面特征零件的磨削过程在线测量,避免了测量控制仪的动作误判及导致磨加工中断等问题,同时保证了磨削加工在线测量的准确性和可靠性。研究成果可以提高磨加工主动测量仪的灵活性和可操作性,丰富完善磨加工主动测量仪的功能。An on-line active measuring method is proposed to solve the problem of grinding the workpiece with intermittent surface.According to the intermittent surface characters of the rotary type workpiece and the grinding performance,some parameters are set and stored in the databases before grinding.When the probe of measuring device enters into the groove of workpiece to judge whether the grooves are periodical distributed on the workpiece surface,it selects the intermittent modifying method or synchronization character compensation method.The mutation measurement values can be modified and compensated automatically during the grinding process,so the action misjudgments of the active measuring instrument and grinding process interrupt can be avoided,and at the same time,the accuracy and reliability of the on-line measuring are improved.The research results can improve the flexibility,operability and function of the active measuring instrument.
