Abstract
Disclosed is a numerical control method for a numerical control (NC) system having a device to execute a mirror image function wherein the moving direction of a movable member is reversed with respect to a commanded direction for each control axis, and a memory device to store coordinate values of a commanded position and coordinate values of a current machine position. This numerical control method comprises a step of storing the respective axial coordinate values of the current machine position at the time that the mirror image function has become effective, a step of calculating the commanded position coordinate values (CP) of directly preceding NC data after the mirror image function has become effective, by using the current machine position coordinate values and the position coordinate values at the time that the mirror image function has become effective, a step of calculating an incremental value (CP.sub.n -CP) of the control axis, CP.sub.n denoting the command position coordinate value of the control axis for which the mirror image function commanded is additionally effective, a step of executing a pulse distribution calculation on the basis of the incremental value, a step of determining the moving direction of the movable member in dependence on the commanded direction and the effectiveness of the mirror image function, and a step of moving the movable member in the moving direction with distributed pulse obtained by the pulse distribution calculation.
