Description
Summary:Abstract An improved chip flow model of a nose-radiused cutting tool in oblique turning is developed considering cutting geometry variations based on the equivalent cutting edge method. The model-building procedure divided the arbitrary cutting area engaged with workpiece into a single edge and a nose-radiused cutting edge according to the depth of cut and tool nose radius. The individual effects on the chip flow angle are distinguished by the equivalent cutting edge method and the total chip flow angle obtained. The chip flow angle prediction results obtained under different cutting parameters show good agreement with experimental data.
