The use of grinding active measurement instrument in grinding process improves the grinding precision,grinding efficiency and grinding automation level. On the basis of studying the active measurement and compensation control,A study on the function of grinding dimension prediction of active measuring instrument has been done so that the dimension prediction can predict the abnormal machining error and provide guidelines for machine tool systems to correct the machining status in advance. Through the analysis of grinding process and the applicability of dimension prediction theories,the grey and compensated moving average forecasting model is established. Experimental verification and analysis show,the average relative error is 0.0067,the root mean square error is 0.3173,the correlation is 0.7682. The dimension prediction applied to the grinding active measuring instrument improves the precision and intelligence of the active measuring instrument,and improves the precision of the measurement,prediction and error compensation control of the grinding system.
