An interactive layout optimization method for two-dimensional rectangular parts based on group technology

Abstract

The invention discloses an interactive layout optimization method for two-dimensional rectangular parts based on grouping technology. The steps of the method include: firstly, completing data preparation; performing grouping of sliced ​​rectangular parts; Carry out blanking and layout in principle; support operators to easily add, delete, rotate, and move slices on the original film through the mouse and keyboard, and can easily zoom in and out the layout of layout; adjust the layout of layout At the same time, the system provides real-time collision detection to automatically ensure that there is no overlap between the slices and that the slices do not exceed the edge of the original sheet; after the interactive nesting is completed, the cutting line and cutting sequence are generated with the total path of the cutting line as the optimization goal. The invention considers the follow-up process, workshop transportation, utilization of the remaining blank area after layout, avoidance of raw material defects, and temporary addition of slices during the blanking process of rectangular parts, and solves the problems of man-machine interactive layout and cutting after layout line generation problem.

Description

technical field [0001] The invention belongs to the field of two-dimensional blanking and layout optimization, in particular to an interactive layout optimization method for two-dimensional rectangular pieces based on the composition technology. Background technique [0002] The so-called Grouping is to combine slices with the same or similar attributes together for interactive nesting. After the layout scheme is formed, it supports manual adjustment of the layout scheme without destroying the layout constraints. [0003] The traditional nesting method does not consider the follow-up process, workshop transportation, workshop scheduling, etc. The slices of the same specification are scattered in the cutting plan, and the cutting lines are messy; the generated nesting plan cannot be adjusted manually, and the human-computer interaction of the nesting plan is poor. . Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an...
