PCT No. PCT/JP82/00118 Sec. 371 Date Dec. 1, 1982 Sec. 102(e) Date Dec. 1, 1982 PCT Filed Apr. 9, 1982 PCT Pub. No. WO82/03590 PCT Pub. Date Oct. 28, 1982.The present invention pertains to a tracer control system for a system performing tracing in an arbitrary direction through using a combination tracer control-numerical control unit which is a combination of a tracer control unit and a numerical control unit, and is intended to increase the cutting accuracy and cutting speed by controlling the feed by tracer control, as compared with a conventional system which controls the feed by numerical control. The numerical control unit is provided with a signal generating device, such as a controller, for generating a signal representing the angle of a feed shaft according to numerical information indicating a path of cutting. The tracer control unit is provided with a first coordinate transformation circuit which generates a displacement component signal in the direction of the feed shaft and a second coordinate transformation circuit for converting, according to the output of the signal generating device, a signal representing the velocity in the direction of the feed shaft into signals for controlling feed rates along the X-axis and the Y-axis. Thereby feed along the X-axis and the Y-axis is controlled by the output of the coordinate transformation circuit. |
