Research on Forecasting and Control of FMS Machining Dimension and Process Capability

On-line modeling and forecasting for machining dimension of FMS is studied and carried out by applying time series analysis theory. Combining the forecasting of machining dimension with that of process capability in a machining process, principle and method of feed-back compensative control is proposed in the paper. After statistical analysis of obtained machining data series in FMS with feed-back compensative control, the results are feasible.
