CALCULATION METHOD, LASER MACHINING DEVICE AND COMPUTER-READABLE STORAGE MEDIUM

WIPO Patent Application WO/2023/020575

A1

A method for calculating a machining starting point, comprising: establishing a first coordinate system and a second coordinate system, where the first coordinate system comprises a CX axis, the first coordinate system is a coordinate system of an image of a workpiece to be machined, the second coordinate system comprises an X axis, a Y axis and a Z axis which are perpendicular to each other, and a plane formed by the X axis and the Y axis is parallel to a bearing platform of a laser machining device; acquiring the image of the workpiece to be machined, and acquiring, according to the image, a first coordinate of a light spot on the CX axis of the first coordinate system, where the light spot is formed by irradiating the workpiece to be machined with light incident from a light emitter of the laser machining device; and calculating a second coordinate of the light spot in the second coordinate system according to the first coordinate, and using the second coordinate as a machining start point. The calculation method can quickly obtain the coordinate of the machining start point, thereby improving the machining efficiency. The present invention also relates to a laser machining device and a computer-readable storage medium.
