Abstract
A laser machining apparatus includes: a laser beam emission device; a visible laser beam emission device; a scanner; and a controller. The controller is configured to perform: generating machining data including coordinate data representing a machining pattern to be machined on a workpiece; machining the workpiece with a laser beam according to the machining data by controlling the laser beam emission device and the scanner; generating, in response to receiving a resuming command after the machining has been halted at a stopping position, a guide pattern based on a stopping point coordinate and the machining data, the guide pattern being used for resuming the machining from the stopping position, the stopping point coordinate indicating the stopping position and being determined by the coordinate data; and projecting the guide pattern onto the workpiece with a visible laser beam by controlling the visible laser beam emission device and the scanner.
