ABSTRACT:
In a system which performs tracer control through the use of a displacement signal of a tracer head tracing the surface of a model, there is provided: a first coordinate conversion circuit in which signals representative of the cosine and sine of the azimuth angle of the feed axis in the X-Y plane of a mechanical coordinate system and X- and Y-axis displacement signals of the tracer head are respectively multiplied by multipliers and the output signals from the multipliers are added together to thereby obtain a displacement component signal of the feed axis; and a second coordinate conversion circuit in which a signal for controlling the feed rate in the feed axis and the signals representative of the cosine and sine of the azimuth angle of the feed axis are respectively multiplied by multipliers to obtain feed rates along the X- and the Y-axis. By controlling the feed rates in the X- and the Y-axis direction with the output signal from the second coordinate conversion circuit, the feed axis in the mechanical coordinate system may be chosen at will.
