Abstract
A forecasting compensatory control (FCC) system was developed to improve workpiece roundness in cylindrical grinding operations. The spindle radial error motion (SREM) at the grinding position, identified as the dominant error source was modeled by an autoregressive model and compensated for by a forecasting algorithm. A digital method for measuring SREM at the grinding position which incorporates master roundness compensation was proposed and a piezo-electric drive system for the generation of the compensatory mechanical motion was developed. The implementation of the proposed method resulted in a substantial improvement of workpiece roundness.
