Embodiment Construction

[0024] The content of the present invention will be described below in conjunction with specific embodiments.

[0025] Before processing, the type of the plate to be processed is classified. Regarding the type classification, it mainly includes two steps, namely, the material division of the plate and the thickness division of the plate.

[0026] a) Material classification: According to the material of the plate to be processed, it is divided into four categories, namely carbon steel, stainless steel, aluminum plate and copper plate. According to the division of cutting difficulty from low to high, carbon steel is the first level, stainless steel is the second level, aluminum plate and copper plate are tied for the third level. Among them, the machinable thickness of the first grade carbon steel is 6-16mm, the machinable thickness of the second grade stainless steel is 3-8mm, and the machinable thickness of the third grade aluminum plate and copper plate is 2-5mm. This is the...

Abstract

The invention relates to a parameter determination method for laser focusing of a cutting machine, comprising the following steps: S1: type division; S2: pre-stop focusing; S3: first penetration; S4: second penetration; S5: interval check ; S6: Trial cutting inspection. The present invention pre-stops according to the empirical processing position, and then uses the dichotomy method to search for the best processing position back and forth, and uses the moving position less than 0.5mm as the first judgment basis to obtain the calibration standard of laser penetration, and uses the complete cutting line As the second judgment standard, the calibration standard of laser cutting is obtained. The present invention is set in this way, its empirical value is pre-stopped, and the multiple check process with two penetrations as a basis group is conducive to quickly finding the best focusing interval, and its multiple checks make the obtained results universal, solving the problem of It solves the focus problem of a product family and can be used as the basis for auto focus programming.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a parameter determination method for cutting machine laser focusing. Background technique [0002] The laser focusing process is the process of calculating the distance from the target to the test instrument by recording the time difference when the infrared laser is emitted from the device, reflected by the target surface, and finally received by the rangefinder. Laser cutting is a processing method widely used in cutting technology. Laser cutting machine has incomparable advantages in cutting metal sheets. It not only has high cutting precision but also has smooth and burr-free cross section. To achieve good results, however, these effects are inseparable from the focus control of the laser cutting machine. When the laser cutting machine cuts different materials and plates of different thicknesses, in order to achieve better cutting results, the focus of the laser beam will be ...
