Problems solved by technology

Moreover, in order to improve the processing efficiency of the machine tool, in the non-cutting state, the cutting head will move and position the plane at a relatively high speed. Since the plate may be uneven, if the cutting head touches the plate during this process, serious problems will occur. accident
[0003] Most of the cutting head controllers currently used in the market only manage the cutting head during the processing process, but there is also a risk of collision during the rapid positioning of the cutting head, and the safety is low

Abstract

The invention discloses a cutting head obstacle avoidance method and device, computer equipment and a medium. The method comprises the following steps: judging whether a cutting head has a collision risk or not in a rapid positioning process of the cutting head; if so, entering a following control state; obtaining the current height of the cutting head, and determining the current expected speed corresponding to the current height according to a speed planning model, wherein the pre-speed planning model comprises a preset mapping relation between the preset height of the cutting head and the expected speed; adopting a preset following control model, and calculating the target jerk corresponding to the cutting head according to the current expected speed; obtaining a real-time regulation and control speed of the cutting head through calculation according to the target jerk; controlling the cutting head to move according to the real-time regulation and control speed; and in the following control state, repeating the steps until the cutting head reaches the preset obstacle avoidance height.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a cutting head obstacle avoidance method, device, computer equipment and media. Background technique [0002] The laser numerical control system performs motion control according to the preset program, and the plane moves according to the program during plane processing. However, due to the particularity of the laser processing field, the cutting head needs to maintain a relatively stable height distance from the plate in order to focus the laser focus on the plate. cutting. Moreover, in order to improve the processing efficiency of the machine tool, in the non-cutting state, the cutting head will move and position the plane at a relatively high speed. Since the plate may be uneven, if the cutting head touches the plate during this process, serious problems will occur. accident. [0003] Most of the cutting head controllers currently on the market only manage the cutting ...
