摘要： A laser processing machine to process a workpiece with laser beams outputted from a laser oscillator. Laser beams outputted from the laser oscillator (1) are projected onto a workpiece (23) through laser beam transmitting means (3, 4) and a condenser nozzle (5). Correspondingly to the movement of the condenser nozzle (5) along a fixed path (7), an angle between two cylinders (3, 4) of laser beam transmitting means changes. However, because of transmission of laser beams through said laser beam transmitting cylinders (3, 4), transmission distances of laser beams do not change. In other words, even when a position of the light condenser nozzle (5) changes, transmission distances of laser beams do not change. Accordingly, processing can uniformly be performed without fluctuating.

摘要： A laser machining method on a CNC laser processing machine for machining a path turning at a sharp angle. The numerical control device (CNC) prefetches a processing program and detects a point at which the path turns at an angle sharper than the allowed one. Processing is continued as usual up to the point (33) of turning at a sharp angle and stopped at this point. Then the vicinity of the point (33) is cooled with a cooling medium for a given period of time so as to prevent the roughness of the cut face from increasing on account of overheating by the laser beam (7). Processing is continued after cooling and performing cutting under conditions for drilling.

摘要： This invention relates to a cut-machining method by a laser beam which cuts a desired product by applying a laser beam to a work to be cut. When an acute angle machining is to be made, the application of the laser beam (15) is stopped at the tip of the acute angle of the work (15), cooling the work by blowing a cooling medium (10) to the tip of the acute angle for a predetermined period, and the cutting work is then continued by applying once again the laser beam (5) from the tip of the acute angle. Accordingly, the tip portion of the acute angle is cooled and machining defect due to overheating of the tip portion of the acute angle can be prevented.

摘要： This invention relates to an NC laser apparatus comprising the combination of a gas laser oscillator equipped with a cooling mechanism for forcibly cooling a laser gas by a blower and a cooler with a computerized numeric controller (CNC). The NC laser apparatus consists of gas temperature measurement means (15) for measuring the inlet gas temperature of the blower, casing temperature measurement means (16) for measuring a casing temperature of the blower and abnormality detection means (24). When the inlet gas temperature or the casing temperature exceeds a predetermined reference value, the abnormality detection means (24) regards it as abnormality of the cooling mechanism and stops the operation of the laser oscillator. Accordingly, abnormality of the cooling mechanism can be detected at an early stage and secondary breakage of the blower (10) can be prevented.

摘要： A method of controlling laser power by controlling the laser output according to an NC instruction and controlling the laser output as a function of the movement instruction speed of a machine. A movement instruction speed is input to a simulator which employs linear or quadratic approximation for a mechanical system, and a laser output instruction value is calculated based on the result of calculation, in order to maintain simultaneity between the moving speed of the mechanical system and the laser output control. Therefore, simultaneity is maintained relative to the laser power projected onto the work to improve the cutting performance.
