Abstract
In this study, forecasting and compensatory control (FCC) techniques are employed to improve the workpiece roundness accuracy in taper turning on an experimental lathe. This paper describes the methodology to online determine, model and forecast the workpiece roundness error using autoregressive (AR) modelling and the aspects associated with its practical implementation on the turning process. Experimental results have shown that an improvement of around 24% was achieved for the roundness error of workpieces in the taper turning operations
