One-step-ahead prediction of flank wear using cutting force

Tool wear prediction plays an important role in the tip geometry compensation during precision machining. The purpose of this study is to develop a reliable method to predict flank wear during a turning process. The force ratio and increment values are applied to predict one-step-ahead flank wear. The results of this paper show that using force ratios, flank wear can be predicted to within 8 and 11.9%, and also using force increment, flank wear can be predicted to within 10.3% of the actual wear for various turning conditions.
