STUDY OF MACHINING PROCESS
MONITORING OF FMS BASED ON
TIME SERIES ANALYSIS*
Abstract:
FMS is a sort of highly automatic machining system, how to ensure part quality is master key to system highly active running. At first, series of machining dimension and process capability of flexible manufacturing system(FMS), is analyzed. Result of its, strong self-correlation of data series shows that time series analysis is applicable to data series analyzed. Based on-line modeling and forecasting for data series, principle and method of feedback compensation control is pro-posed. On a foundation of the virtual instrument platform, Labview of national instrument (NI), FMS dimension and process capability monitoring system(monitoring system) is developed. In practice, it is proved that part quality and process capability of FMS are greatly improved.
