Abstract
A laser processing apparatus including a processing nozzle for irradiating a workpiece with laser beam; an actuator for moving the processing nozzle relative to the workpiece; a distance detector for detecting a gap between the processing nozzle and the workpiece; a power abnormality detecting section for detecting an abnormality in electric power supplied from a power supply unit; a gap control section for controlling the actuator based on a detected value obtained by the distance detector, so as to perform a gap control for adjusting the gap to a target value, during execution of laser processing; and a change control section for maintaining the gap control in an enabled state until a power abnormality is detected by the power abnormality detecting section during execution of laser processing, and for disabling the gap control when a power abnormality is detected by the power abnormality detecting section during execution of laser processing.
