Abstract
This paper presented a general model for predicting the cutting forces in oblique cutting operation with respect to vector transformation derived from orthogonal cutting process. The developed model is based on that the fundamental mechanics of the friction relationship between tool and material (chip) at the primary and secondary shear zones are the same when the flowing relationship between tool and chip is the same for the cutting processes with different inclination angles, including the orthogonal cutting process, in which inclination angle is 0. The cutting force loading on tool rake face in oblique cutting process with any inclination angle can be determined by the orthogonal cutting force data with the same tool-chip flowing relationship. To achieve precision orthogonal cutting force data, a mechanics model for orthogonal cutting process considering cutting speed, rake angle, and depth of cut is proposed and the predicting coefficients are calibrated by a set of turning tests. At last, a series of experiments under different cutting conditions are conducted to confirm the validity of the developed model. There is a good agreement between the experimental and simulative results, which shows the model is effective for cutting force prediction in orthogonal and oblique cutting operations.
