Abstract
A control system for moving a machining member relative to a workpiece table in accordance with a set of programmed input instructions which correspond to a prescribed path of movement, including a main contour control logic to generate output signals to move the machining member relative to the table in accordance with the stored values of the components I and J of a main contour vector, a sub-contour control logic which generates output signals to move the machining member based on the stored values of the components i and j of a sub-contour vector, and cutter compensation control logic which enables either the main or the sub-contour control logic to operate based on a determination of whether the main contour vector is leading or lagging the sub-contour vector.
