TRACER TYPE METAL WORKING MACHINE WITH IMPROVED FEATURES ABSTRACT OF THE DISCLOSURE A metal working machine has a tracer and co- ordinate drive control which are connected through the X and Y drive motors and encoders to an input of a CNC unit mounted on the machine. The CNC is separately connected to a tape recording device and can record the tracer movements on the tape. Additional machine commands can be added via the CNC. The CNC memory can be loaded or programmed either via the tracer itself or subsequently from the recorded tape for later machine controlling playback independent of the tracer or tape. The CNC is further connected to a digitizing device which makes it possible to reduce the amount of positional in- formation which must be stored by the memory. This is accomplished by manually or automatically varying the positional sampling rate according to the contour and dimensions of the workpiece. When the sampling rate is varied automatically, the information reduction device is provided with a feedback from the tracer. More specifically, and in either the manual or automatic mode, the positional sampling rate is controlled by a variable repetitive timer.
