【Abstract】 The mathematical treatment of programe processing is complex while refining curved plane of cubic components with NC milling machines. Its difficulty lies in the coordinate calculating of pitch point and the path calculating of tool position point. The numerical calculation involved in the refining of curved helical plane with NC milling machines is analyzed in general. The formular of coordinate calculation and path calculating of tool position point are further examined.Accordingly,the mathematical basis is proviced for computer-aided-calculating.The above mentioned method is applicable to the mathematical treatment of involute curved helical plane as well as bevel curved helical plane.更多还原
