Two-dimensional rectangular part interactive layout optimization method based on grouping technology

Abstract

The invention discloses a two-dimensional rectangular part interactive layout optimization method based on a grouping technology. The method includes the steps that firstly, data preparation is completed; grouping of sliced rectangular parts is performed; a leftmost and bottommost optimization principle is used for material discharging and layout; the functions that an operator can adding, deleting, rotating and moving slices on an original sheet conveniently through a mouse and a keyboard are supported, and the layout can be zoomed in and zoomed out conveniently; when the layout is regulated, a system provides real-time collision detection, and the situations that the slices do not overlap and cannot exceed the edge of the original sheet are guaranteed automatically; after interactive layout is completed, a cutting line total path is used as an optimization objective to generate cutting lines and cutting sequences. According to the two-dimensional rectangular part interactive layout optimization method, in the rectangular part discharging process, the problems of follow-up processes, workshop transportation, utilization of residual blank areas after the layout, raw material defect avoiding and temporary slice adding are considered, and problems generated by man-machine interactive layout and the cutting lines after layout are solved.

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...
