ABSTRACT:
In a tracer control system which controls tracing based on displacement signals from a tracer head tracing the surface of a model, there are provided position detectors for detecting the positions of a tracing machine along the X, Y and Z axes and angle correcting means. The difference between a set trace direction and the actual trace direction detected by the position detectors is obtained for every other fixed distance of movement along the X-axis or Y-axis direction and a trace velocity along the X-axis or Y-axis direction is corrected by the angle correcting means so that the above difference may be reduced to zero, thereby controlling tracing to be performed in the set trace direction.
