Abstract
In this study, forecasting and compensatory control (FCC) techniques a re employed to improve the workpiece roundness accuracy in taper turni ng on an experimental lathe. The paper focuses on the development and implementation of both hardware and software associated with the forec asting and compensation system. The tasks involve the in-process error measurement, off-line error modelling and simulation and on-line erro r forecasting and compensation. Experimental results have shown that a n improvement of 24-38% was achieved for the roundness error of workpi eces in the taper turning operations. (C) 1998 Elsevier Science B.V.
