Automobile plate laser cutting automatic typesetting and drawing method and system

Abstract

The invention discloses an automobile plate laser cutting automatic typesetting and drawing method and system, and the method comprises the steps: firstly generating an offset polygon of each type ofworkpieces relative to the remaining types of workpieces, and generating an internal adaptive rectangle formed by each type of workpieces in a raw material plate; determining a current to-be-typeset workpiece according to the drawing sequence, taking a union set of offset polygons between the to-be-typeset workpiece and each typeset workpiece, and calculating a complementary set of the union set in an inner adaptive rectangle of the to-be-typeset workpiece to obtain a typesettable area of the to-be-typeset workpiece; calculating the layout integrating degree of the to-be-typeset workpiece at each position point in the typesettable area, and taking the position point with the highest layout integrating degree as the typesetting position of the to-be-typeset workpiece; and finally, accordingto the drawing sequence, carrying out typesettable area calculation and typesettable position selection on each workpiece to be typeset until typesetting of all the workpieces to be typeset on the raw material plate is completed. According to the method, waste of raw material plates is reduced, and the machining efficiency is improved.

Description

technical field [0001] This application relates to the technical field of plate cutting, in particular to a method and system for automatic typesetting and drawing of laser cutting of automobile plates. Background technique [0002] In the manufacturing process of auto parts, it is necessary to produce metal sheets that meet the required shape first, and then carry out such as stamping, painting, assembly and welding, and finally get the finished auto parts, and finally assemble each auto parts to get whole car. For the production and manufacture of auto parts, one of the main methods currently adopted is to laser cut raw steel plates with a certain width and thickness according to the shape of the parts, cut out steel plates with corresponding shapes, and then process the steel plates. Subsequent processing, and finally get the finished auto parts. [0003] At present, in the plate cutting process, the arrangement order of the shapes of the automobile workpieces on the ra...

Problems solved by technology

[0004] The above-mentioned way of arranging the shapes of the workpieces will cause a large gap between the shapes of the automobile workpieces, and a large amount of blank raw materials will not be cut and processed when passing through the cutting equipment, resulting in a large waste of raw material plates during the production process, and will also lead to production. low processing efficiency
