摘要

A fast-forward movement command for moving the relative position between the machining head and the workpiece at the first movement speed, and a linear interpolation movement command for moving the relative position at the second movement speed in a state of following the workpiece. In the NC program generation device that generates an NC program used for laser processing using the above, the first movement time of the relative position when the fast-forward movement command is used and the relative position when the linear interpolation movement command is used A travel time calculation unit (19) for calculating the second travel time, a travel method selection unit (21) for selecting a travel command corresponding to the shorter one of the first and second travel times, and a selection An NC program generation unit (22) for generating an NC program by setting the movement command between the machining points.
