Abstract: A suction unit control method includes simulating an air flow about a suction port, through which fumes generated when a laser beam is radiated on a target substrate on a stage unit to cut the target substrate are sucked up, installing an air blower on three or four sides around a laser cutting end at a height close to the suction port, controlling on and off of first to fourth solenoid valves of the air blower based on a movement of the stage unit while performing laser cutting on the target substrate while moving the stage unit.
