Abstract
A clamping tracer control system which performs a tracing feed and a pick feed alternately and effects a clamping feed at a preset clamp level and in which, between the pick feed position where the clamping feed is carried out first and the pick feed position where the clamping feed has been completed, tracer control is repeated while changing the clamp level sequentially, and when the clamping feed has been completed in the repeated tracer control, the clamp level is restored to its area of initial value to resume tracer control of the tracing feed and the pick feed alternately in the next area.
