Graph cutting and sorting processing method applied to laser cutting numerical control machining

Abstract

The invention relates to a graph cutting and sorting processing method applied to laser cutting numerical control machining. The method comprises the following steps of: importing a CAD file into a laser numerical control system, converting the CAD file into primitive data according to a file format, and selecting primitive data to be machined; judging whether at least one closed outer frame primitive exists in the selected primitive data and at least two circular hole primitives exist in the selected primitive data or not, wherein if so, the steps are continued, and otherwise, the sorting fails; performing strategy sorting on the processing angle and the processing path trend direction of the primitive data; and sequentially converting the primitive data into G code processing files according to a sorting result, importing the G code processing files and processing the G code processing files. By the adoption of the graph cutting and sorting processing method applied to laser cuttingnumerical control machining, the cutting sequence can be connected into a straight line according to the rule that the round holes are formed from bottom to top or from left to right, the round holesconnected front and back can be in parallel transition, the cutting efficiency is improved, and the machining effect can be improved.

Description

technical field [0001] The invention relates to the field of plane cutting numerical control processing, in particular to the field of laser cutting numerical control sorting, and specifically refers to a graphic cutting sorting processing method applied to laser cutting numerical control processing. Background technique [0002] There are many CNC laser cutting methods in the market, but the cutting sequence is basically rigid and not suitable for plane laser cutting. The CAD features of planar cutting are as follows: there is an outer frame, and there are many round holes inside the outer frame. It is required to cut the outer frame after cutting the round holes. Therefore, the arrangement of the cutting sequence of the inner round holes is extremely important. A good cutting strategy It can greatly improve processing efficiency, save cost and improve processing effect. The cutting methods on the market are basically divided into the following types: 1. X-axis and Y-axis ...

AI Technical Summary

Problems solved by technology

The cutting methods on the market are basically divided into the following types: 1. X-axis and Y-axis cutting, sorting the graphics elements according to X or Y coordinates, this strategy is simple and clear, but it cannot recognize the internal circular hole layout characteristics, rigid The layout strategy will make the knife be raised frequently during cutting, and the efficiency will be reduced; 2. From the outside to the inside, start along the outer border of the word, and cut inward layer by layer. This strategy takes into account the layout characteristics of round holes, but it is not the best Perfect sorting strategy, the shape characteristics of the outer frame are not necessarily suitable for the arrangement of round holes, and it is impossible to make the transition paths between multiple round holes tend to be parallel, improving efficiency and effect
