APPARATUS FOR CONTROLLING PROFILING.

摘要

An apparatus for controlling profiling is improved so that it is possible to easily vary a reference displacement quantity during machining. A profiling calculation means (2) calculates a profiling rate and a profiling direction on the basis of a displacement quantity detected by a tracer head (1) and the output of an adding means (4). A driving means (3) moves the tracer head (1) and a model relative to each other on the basis of the results of the calculation carried out by the calculation means (2). The adding means (4) adds together a reference displacement quantity stored in memory (5) and a correction set by a correction setting means (6) and inputs the result of the addition to the profiling calculation means (2).
