Abstract
A tracer control system which performs tracer control based on a displacement signal from a tracer head tracing the surface of a model and is equipped with the function of freely setting the infeed of a cutter for machining a workpiece. The tracer control system is provided with a first drive system for feeding the tracer head in the Z-axis direction, a second drive system for feeding the cutter head in the Z-axis direction, first and second position detectors for detecting the positions of the tracer head and the cutter head in the Z-axis direction, and a superimposing circuit for superimposing on each other a position detection signal from the first position detector and an infeed command signal for setting the infeed of the cutter head. The cutter head is fed by the second drive system in the Z-axis direction so that the difference between output signals from the superimposing circuit and the second position detector may be reduced to zero.
