金型型面実時間加工システムの開発

抄録

In the case of sculptured surface NC machining, NC data are constructed with sequential NC blocks instructing a small movement of less than 1 mm. In order to realize high-speed processing of enormous volumes of NC data, a high-speed data communication interface and a NC adapter which can generate servo data in the binary format have been developed. However, if the curved interpolation function is implemented in the CNC controller, these equipments will be unnecessary. Further-more, if the tool path can be generated in the real-time mode, intermediate processings like NC data storage and format conversion will be shortened. The CNC system described in this paper has two functions : real-time tool path generation and curved interpolation. It can accept geometrical data and generate tool path automatically. All cutter location data are directly input to the servo process. This controller realizes the same machining style as a copy milling machine which are real-time machining in shop floor and also high operationability and high-accuracy machining. These features will improve productivity of molds and dies.
