| Abstract: | For precision machining, the hard turning process is becoming an important alternative to some of the existing grinding processes. This paper presents an analytical model for predicting cutting forces in hard turning of 51CrV4 with hardness of 68 HRC. The cutting tool used is made from cubic boron nitride (CBN) with a wiper cutting edge. Formulas for differential chip loads are derived for three different situations, de- pending on the radial depth of cut. The cutting forces are determined by integrating the differential cutting forces over the tool-workpiece engagement domain. For validation, cutting forces predicted by the model were compared with experimental measurements, and most of the results agree quite well. |
