Embodiment

[0022] see figure 1 and figure 2 , the present invention provides a kind of technical scheme in conjunction with workpiece cutting shown in the figure:

[0023] A laser cutting method for workpieces using CO 2 The combination of laser cutting and auxiliary gas includes the following steps:

[0024] (1) Initialize the laser cutting system and adjust the CO 2 Laser beam;

[0025] (2) Clamp and position the workpiece to be cut;

[0026] (3) Use an air compressor to compress and purify the air to form auxiliary gas, and transport it to the laser cutting position;

[0027] (4) A cutting line with a predetermined shape is formed on the surface of the workpiece, and a corresponding cutting auxiliary line 02 is formed immediately adjacent to the cutting line 01 , which is consistent with the shape of the cutting line.

[0028] (5) According to the material and specifications of the workpiece, set the corresponding process parameters of the system so that the CO 2 The laser bea...

Abstract

The invention discloses a laser cutting method for a workpiece. The laser cutting method combines CO2 laser cutting with auxiliary gas and comprises the following steps of: (1) initializing a laser cutting system, and adjusting a CO2 laser beam; clamping and positioning a workpiece needing to be cut; (2) compressing and purifying air by using an air compressor to form auxiliary gas, and conveyingthe auxiliary gas to a laser cutting position; (3) forming a cutting line with a preset shape on the surface of the workpiece, and forming a cutting auxiliary line at the position close to the side; (4) according to the material and specification of the workpiece, setting corresponding technological parameters for a system, and thus coaxially outputting the CO2 laser beam and the auxiliary gas tothe workpiece; and (5) conducting scanning and cutting once along the path of the cutting line through the output CO2 laser beam and the output auxiliary gas until the workpiece with the required preset shape is finished. The method is simple, reliable, higher in cutting strength, accurate in cutting and high in precision.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser cutting method for workpieces. Background technique [0002] Laser cutting rate density The laser beam irradiates the material to be cut, so that the material is quickly heated to the vaporization temperature, and evaporates to form holes. As the beam moves to the material, the holes continuously form a narrow (such as 0.1mm) slit. Finish cutting the material. Due to the ultra-fast speed, high precision and high accuracy of laser cutting, it is widely used in the field of industrial product processing, especially CO 2 Laser cutting has the most applications. [0003] According to the above-mentioned existing laser cutting methods, when encountering high-strength workpiece products such as highly chemically strengthened glass substrates, due to the characteristics of the pulsed laser beam, it is not easy to separate the high-strength workpiece quickly, resulting...
