Laser cutting control method and device and storage medium

Abstract

The invention discloses a laser cutting control method and device and a storage medium, and the method part comprises the steps that a plurality of target cutting parts on a to-be-cut part are determined, and contour line intersection points between the different target cutting parts are determined; pre-cutting points are determined on the contour line of the target cutting part so as to obtain a plurality of pre-cutting points, and the distance between the pre-cutting points and the cross point of the closest contour line is larger than the radius of a nozzle of the laser cutting head; according to the multiple pre-cutting points and the cross points of the contour lines, multiple cutting paths of the to-be-cut piece are determined, and the end point of at least one cutting path is the pre-cutting point; a laser cutting head is controlled to conduct laser cutting on the to-be-cut part according to the multiple cutting paths, so that multiple target cutting parts are obtained; according to the laser cutting device, the safe distance between the laser cutting device and the contour intersection point can be kept as far as possible, the possibility that a cutting head makes contact with a tilted cutting angle is reduced, and therefore normal proceeding of laser cutting work is guaranteed, and the working efficiency of laser cutting is improved.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a laser cutting control method, device and storage medium. Background technique [0002] Laser cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, low processing cost and high production efficiency. It has become one of the main sheet cutting methods. [0003] However, in the actual cutting process, especially in the common-edge cutting process, the cutting corner of the part formed after cutting is often warped due to thermal deformation or gravity. When the cutting head needs to perform cutting work near the cutting corner of the part, the cutting head is very It is possible to encounter a raised part cutting corner, causing deformation of the cut workpiece, and even the possibility of damage to the cutting head. Therefore, when the cutting head collides, the laser cutting device will stop...
