A CAM system which is based on simulating the servo data generation method of a copy milling machine was developed. In this system, the tool path data can be directly calculated using the coordinates of the contact point between the defined shape and the imaginary stylus, without preceding processes of offset surface generation and tool interference checking. For application of this algorithm to the model which is expressed by the boundary representation method, the algorithm has been modified slightly. As the contact point is regarded as the nearest point to the center of the imaginary stylus, and which is on the model surface, all intervals between the center of the imaginary stylus and the constructing surfaces which are close to it are calculated. The point which has the shortest interval is the representative nearest point of the model data and the contact point in the case that the interval is equal to the radius of the tool. A roughing tool path which is constituted with imaginary block and a spiral finishing tool path which tool feed with smoothly cutting have been developed using the algorithm. Tool path simulations and cutting tests show that the developed CAM system was able to generate appropriate CL data with high accuracy and reliability.
