车刀的主要几何参数及其选择

The Main Geometric Parameters of Turning Tool and Their Determination

车刀应该根据加工材料和加工工艺要求,灵活选用刀具材料,确定刀具前角、后角、主偏角、副偏角、刃偏角等几何参数,以保证加工精度。

According to the processing materials and technology requirement, the materials of turning tool should be flexibly adopted and the main geometric parameters including rake angle, relief angle, cutting edge angle, assistant de- flection angle and blade obliquity should be flexibly determined, so as to ensure machining precision.
