Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] In the optimization of the nesting material management, the present invention mainly manages the nesting material basically in the following seven aspects:

[0058] (1) Preparation of nesting data: nesting requires part data, whole material data and remaining material data. Once the material enters the nesting process, the material cannot be used by other personnel or other tasks as the preparation of nesting data, that is, into a locked state. The invention can effectively add materials to the task data, so that the amount (area) of the material is greater than or equal to the amount (area) of the parts, which improves the success rate of nesting and avoids the operation of returning to nesting again due to insufficient materials. Dead time is reduced.

[0059] (2) Import and export of nesting data: After the nesting data is prepared in the pr...

Abstract

The invention discloses an optimized management method for a trepanning task of digital shipbuilding, which comprises a step of preparing trepanning data, a step of leading in and leading out the trepanning data, a step of post-processing trepanning, a step of allocating materials, a step of cutting in the field, a step of recording residual materials, and a step of outputting a trepanning drawing and a result report. According to the optimized management method for the trepanning task of the digital shipbuilding, the trepanning result is efficiently integrated and optimized, and the cutting idle running length is shortened; in addition, a basic intelligent management of trepanning is implemented.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to three optimized nesting methods applied in the cutting design process of nesting, in particular to a nesting task management method for digital shipbuilding. [0002] Background technique [0003] Nesting is a very important link in ship production design. All plates are cut and produced from nesting. The quality of the nesting results directly affects the utilization rate of materials, and ultimately affects the production cost and economic benefits of the enterprise. [0004] The research on the optimization of ship nesting started earlier in foreign countries. Kantorovich first proposed the one-dimensional nesting problem in 1930; in the early 1960s, Gilmore et al. proposed the one-dimensional nesting scheme and the two-dimensional nesting optimization problem, and completed He used linear programming to establish a mathematical model of one-size-fits-all problems, and transforme...
