摘要： A laser beam machine easily prepares a data bank of machining conditions and also easily creates a machining program from the machining conditions. When a suitable trial machining condition D1 is derived, the trial machining condition D1 is stored in a memory area as the machining condition for a machining step concerned. The machining condition is stored in accordance with a signal entered by an operator to create a machining condition data bank. In addition, an output state data D2 of a laser oscillator obtained during laser beam machining according to the trial machining condition D1 is stored. A registration code is assigned to the machining condition and the stored output state data. A machining condition corresponding to a machining path specified in a generalized machining program P.sub.0 is extracted from the machining condition data bank and the extracted machining condition is set in the generalized machining program to create a specific machining program P.

摘要： A piercing method using a laser, in which the processing time is made shorter; a thermal runaway is prevented; and dispersion of the processing time is made smaller. According to this method, piercing operation is started with an initial pulse frequency P.sub.0 and an initial pulse duty ratio Q.sub.0, and the pulse frequency and the pulse duty ratio are increased by increments P and Q, respectively, with every passage of a predetermined time T. The pulse frequency and the pulse duty ratio are increased by stages. After this increase is repeated a predetermined number of times, or after the passage of a predetermined time from the start of processing, processing is continued to the end maintaining the increased values. This piercing method enables the processing time to be reduced to 1/3 to 1/5, as compared with the conventional method. In addition, this method prevents a thermal runaway, and reduces the dispersion of the processing time.

摘要： A laser beam machining method for cutting a workpiece in accordance with a machining program composed of a succession of move commands and laser output commands. An angle of a machining path is calculated on the basis of a move command under execution and a subsequent read out move command (S2, S3). The angle of the machining path is compared with a preset angle (S4), and when the angle of the machining path is more acute than the preset angle, the movement for machining based on the move command under execution is decelerated and stopped (S5). In this case, the laser output command is changed from a cutting condition to a piercing condition, to carry out a piercing operation, and when the piercing operation is completed, the movement for machining is restarted in accordance with the subsequent move command. When the movement for machining is restarted, the laser output command is changed from the piercing condition to the cutting condition in accordance with the movement for machining. Accordingly, a clean-cut acute-angle portion can be obtained by this machining.

摘要： A laser beam machine which makes it possible to effect piercing in a shortest time period and cutting with high accuracy. A program-reading device reads a machining program. A first distance changeover-directing device directs that a workpiece-to-converging point distance between a surface of a workpiece and a converging point of a laser beam is set to one value suitable for piercing when it detects a piercing program in the machining program. Further, a second distance changeover-directing device directs that the workpiece-to-converging point distance is set to one value suitable for cutting when it detects a cutting program in the machining program. A distance control device operates to control the workpiece-to-converging point distance in accordance with directions from the first and second distance changeover-directing devices. That is, the workpiece-to-converging point distance is set to the optimum value for piercing when piercing is carried out, while it is set to the optimum value for cutting when cutting is carried out, thereby completing piercing in a short time period, and effecting cutting with high accuracy.

摘要： Oxygen is mixed with another gas to form an auxiliary gas that will permit a welding of zinc-plated steel sheets (3a and 3b) without producing blowholes. An oxygen (O.sub.2) gas cylinder (4a) is provided in addition to an argon (Ar) gas cylinder (4b), for forming the mixed auxiliary gas, and the argon gas and the oxygen gas are mixed in a mixer (6) before being supplied to a machining head (7) and jetted onto a machining spot (9) through a nozzle (8). The oxygen oxidizes the zinc of the zinc-plated steel sheets (3a and 3b) to produce zinc oxide and zinc peroxide, to thereby prevent evaporation and minimize spatters, and thus permits a laser welding with a minimum generation of blowholes.

摘要： A laser beam machine executes a cutting operation by irradiating a laser beam onto a workpiece. The cutting operation of nonferrous metals having a considerable thickness is executed effectively and stably. A piercing operation is executed at point A under machining condition A, forming an arc-shaped portion. Then, the machining condition A is changed to machining condition B to execute an enlargement processing, and the arc-shaped portion is extended as it is, forming an enlarged cutting groove. After the enlargement processing is completed at point B, the standoff (or distance from the tip end of a machining nozzle to the surface of the workpiece) is set to as short a distance as possible, and the machining condition is modified to machining condition C. Thus, a cutting operation is started according to machining condition C. Therefore, the cutting operation is executed in substantially the same state as that in which a cutting operation is started directly from the outer-side end of the workpiece. In addition, in the case where the cutting operation is executed, the assist gas pressure is set to a high value, and the standoff is set to a low value, so that dross scattering effect by the assist gas appears more remarkably. Thus, the cutting operation is executed effectively and stably.

摘要： Surface-treated metallic workpieces such as zinc-plated steel plates are welded with high quality while they are being held in intimate contact with each other. An auxiliary gas including an oxygen gas is ejected from a space (7) around an electrode (1) through a nozzle (8) to a welding point (9) on overlapping surface-treated metallic workpieces such as zinc-plated steel plates (3a, 3b). When the zinc-plated steel plates (3a, 3b) are welded in the atmosphere of the auxiliary gas, the surface layers of zinc and oxygen react with each other, producing a solid oxide such as zinc oxide or zinc peroxide. Therefore, a gas such as a zinc vapor is prevented from being produced between the overlapping zinc-plated steel plates (3a, 3b). The welded joint is of high quality without blowholes which would otherwise blow away molten steel.
