Abstract: A laser cutting device includes a control unit configured to control operations of a laser machining robot and a laser oscillator. Machining condition tables are stored in memory of the control unit. Each of the machining condition tables includes data of a laser power output and a duty, a usable range of a cutting speed of cutting a workpiece, the usable range being set based on a speed range in which a laser cutting robot can move with given tracking accuracy, and an effective range of the cutting speed and the laser power output that are set so that a cut surface of the workpiece meets given finishing conditions. The control unit is configured to select one of the machining condition tables so that the cutting speed and the laser power output meet given conditions, and control cutting of the workpiece based on the selected machining condition table.
