Abstract

The invention provides a method for optimizing the track of an engraving machine. The method includes the steps of converting a given processing track into a generalized traveling salesman model, solving the generalized traveling salesman model by using an improved ant colony algorithm, and obtaining the shortest path and the corresponding processing track sequence. After the track data are converted into a mathematics model that can be optimized through an algorithm, the ant colony algorithm is employed to optimize the track data, and the ordering optimization of given track is realized. Convergence speed is accelerated, and the precision of the optimal solution is ensured. The method is flexible and practical, and the processing efficiency of an engraving machine is substantially improved.

Description

technical field [0001] The invention relates to a trajectory optimization method for an engraving machine, including a processing method for a given trajectory and an optimization method for a processed trajectory. Background technique [0002] An engraving machine is a device that uses a machine instead of manual engraving, which is equivalent to a combination of drilling and milling processing equipment. The engraving machines on the market directly execute the engraving trajectory generated by CAM software, and their processing efficiency is deeply affected by the quality of the processing trajectory generated by CAM software. These CAM software are usually developed by professional software companies. The production of engraving machines It is difficult for suppliers to change the quality of the processing path through CAM. Therefore, when the engraving machine system executes the processing trajectory, it is very necessary to optimize the processing trajectory first. ...
