磨削加工对象多变时砂轮状态在线监测方法

On-line monitoring method of state of grinding wheel on grinding objects changing

在磨削加工对象频繁更换的情况下 ,工件的材料、加工要求、磨削条件和磨削参数经常变化 ,使声发射信号的信息也随之发生变化 ,为此提出基于声发射信号多变情况下的归原处理法 ,用于多变磨削加工环境下砂轮状态的在线监测。

While grinding objects changing frequently,following it,the information of acoustic emission signal is also changing because of workpiece material,machining desire,grinding condition and grinding parameters are varying.For this reason,presents returning original processing method,it can be used to measure the wear state of grinding wheel under condition varying frequently and its feasibility has be verified through experiment.
