Abstract

The invention relates to the technical field of component machining, in particular to a fly-cutting trajectory planning method, a fly-cutting control method and a fly-cutting system. The fly-cutting trajectory planning method comprises the following steps of screening out linear trajectory segments from a to-be-processed primitive; grouping the screened linear track segments according to whether the linear track segments are collinear or not; sequentially connecting the collinear linear trajectory sections through connecting straight lines to form at least one linear fly-cutting trajectory; when the number of the linear fly-cutting trajectory is one, taking the linear fly-cutting trajectory as a final fly-cutting trajectory; and when the number of the linear fly-cutting trajectories is multiple, connecting the adjacent linear fly-cutting trajectories in a snakelike mode through the connecting steering lines, so that a final fly-cutting trajectory is formed. According to the fly-cutting control method, control is performed according to the final fly-cutting trajectory. The fly-cutting system adopts the fly-cutting control method for cutting. According to the fly-cutting trajectory planning method, the fly-cutting control method and the fly-cutting system, more reasonable path planning is provided for a cutting head through the final fly-cutting trajectory, the machining time is saved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of component processing, in particular to a fly-cutting trajectory planning method, a fly-cutting control method and a fly-cutting system. Background technique [0002] Laser flying cutting is to use a high-power density laser beam to irradiate the material to be cut along the pre-planned flying cutting track, so that the material is quickly heated to the vaporization temperature, and evaporates to form holes. As the laser beam moves relative to the material, the holes continuously form width Very narrow kerf to complete the cutting of the material. [0003] In planar laser cutting, there are a large number of straight line segments to process part tracks. These straight line segments may be connected or may be far away. How to quickly complete the cutting of a large number of straight line segments to save processing time is a common problem. [0004] In the related art, the processing of laser cutting is ...
