| Abstract: | The principle, method and results of direct interpolation control of the tool path for sculptured surface machining in a CNC system is described. With such a CNC system, the engineering surfaces can be machined at high speed with high accuracy according only to the geometric data and machining parameters. On line variation is possible for the machining parameters such as the tool dimensions and machining allowance. High level language similar to APT can be directly used. The programming work and NC coding for surface machining are greatly simplified. As a result, surface finishing can be made cheaper. |
