Modeling of turning process cutting forces for grooved tools

A mechanistic modeling approach to predicting cutting forces for grooved to ols in turning has been developed. The model assumes the existence of an eq uivalent orthogonal cutting operation for any oblique operation. The effect s of tool nose radius and chip flow have been incorporated by defining a se t of equivalent groove parameters. Two calibration methods have been presen ted for the model. A variety of commercial grooved inserts were chosen to v alidate the model. The workpiece material used was AISI 1018 steel. The for ce predictions from the model were found in good agreement with the measure d forces. The effects of cutting conditions and groove parameters on the cu tting forces and their implication in designing grooved tools were also det ermined. (C) 2001 Elsevier Science Ltd.
