<p>A profile control method by which a work is machined by profiling a model with a tracer head. Two axes (X, Y axes) NC-instruct an instruction path and a speed, and three axes (X, Y, Z axes) make profile control. An NC instruction speed is changed by an override circuit (2b) so that the NC instruction speed (F) is in conformity with a combined speed of the three axes by the profile control, and as a speed Fd is sent to an interpolator (2a). The path by the two axes serves as an NC instruction path, the speed acts as profile control speed and they provide a motion which is equivalent to the profile control path by the three axes.</p> |
