Abstract
It presents the characteristics of cylindrical cams working surfaces for S-shaped involute cam and the resulted machining difficulties.By example about involute cam machining,detailedly indroduces the analysis method of the macro program method using in the non-circular curve surface part.The method can be used in other parts widely.The programming method can be used for other complex curves and surfaces' CNC machining.For the expansion of system functions,this methods giving full play to the performance of CNC machine tools provides a reference.
