Merchant [1]，Lee and Shaffer[2], Oxley[3], Pamler[4] are the earlier representatives that established some simplified Materials Science Forum Vols. *** 17 models and explored the relationships amongst shear angle, tool rake angle and tool-workpiece friction.
The rake angles, 0°, 5°, 10°, 15° and 30° are used when Advances in Materials Manufacturing Science and Technology 18 the cutting edge radius is 0.3mm.
From the simulation results, the following conclusions can be drawn out: Advances in Materials Manufacturing Science and Technology 20 1) The model, where workpiece is moved with cutting velocity and the tool is fixed, can be used to simulate orthogonal cutting.
