【Abstract】 It is an important factor that tool size affects the quality and efficiency of complex curved surface of CNC machining. This paper starts with analyzing the functional relationship between the tool size and the quality and efficiency of complex curved surface,gives the selection method of optimal minimum tool which can ensure the precision of machining curved surface,establishes optimal selecting algorithm of reasonable large size tool with the most high efficiency as the objective,and for the curved surface of complex geometric features,tool combination selection method with effective area ratio of tool machining as a reference is put forward. Application examples show that the optimal selecting strategy of tool size,under the premise of adequately ensuring the machining quality of complex curved surface can effectively improve the whole machining efficiency.更多还原
