Abstract
The gap control axis following speed calculating unit of a numerical controller controlling a laser processing machine calculates a gap control axis following speed based on a displacement amount obtained from a separation distance and a reference distance between a nozzle tip and a workpiece, and a gap control gain. A first determining unit determines that the nozzle tip has entered an approach side when the separation distance becomes smaller than the reference distance. A first changing unit changes the gap control gain continuously in accordance with the displacement amount.
