ABSTRACT:
A numerical control method and apparatus for controlling the movement of a movable member by setting entry forbidden areas which the movable member is forbidden to enter. Entry forbidden information relating to the boundaries of the entry forbidden areas is created and stored in memory, the current position of the movable member is monitored, the entry forbidden information is used to determine whether the current position of the movable member has entered a forbidden area, and the movement of the movable member is halted when the current position thereof has entered an entry forbidden area.
