Abstract
A numerical value controller includes a storage unit that stores a machining program involving executing a plurality of canned cycles each including a first operation for positioning a drilling position of a workpiece relative to a tool, a second operation for moving the tool from a return point to a hole bottom point, and a third operation for moving the tool from the hole bottom point to the return point; a control unit that controls movement between the tool and the workpiece based on the machining program and that moves the tool along curved paths by starting the second operation before the first operation ends and starting the first operation in a subsequent canned cycle before the third operation ends; a distance calculating unit that calculates a retraction distance; and a curvature calculating unit that reads a positioning command for the drilling position for the subsequent canned cycle.
