Technological process determination method and device, server and storage medium

Abstract

The invention provides a technological process determination method and device, a server and a storage medium, and aims to improve the solving efficiency of a technological process, and the method comprises the steps: combining steps, which must be processed in the same process, in a workpiece, and obtaining at least one step group of the workpiece; on the basis, taking the minimum cutter cost asthe target, and solving the process to which each step group of the workpiece belongs according to the machining constraint, so that the minimum cutter cost for machining the workpiece is realized; and finally, the inter-step sequence of the workpiece in the same process and the inter-step sequence in the step group are adjusted based on the inter-step machining sequence constraint of the workpiece to generate a machining process sequence (i.e., the process flow) of the workpiece, so that the solving precision of the process flow of the workpiece is further improved.

Description

technical field [0001] The present invention relates to the technical field of process planning, and more specifically, relates to a method, device, server and storage medium for determining a process flow. Background technique [0002] With the continuous development of society, the development of automobile manufacturing industry is getting faster and faster. The production of engine block is one of the important links in automobile manufacturing, and the pros and cons of the process planning method for producing engine block directly affects the cost of automobile manufacturing. [0003] The machining process of automobile engine block contains hundreds of machining features, and each machining feature has its own independent machining standard requirements (including machining surface, machining datum, machining error, machining time, machining tools, etc.), so how to integrate hundreds of It is a complex combinatorial optimization problem to plan a processing feature i...

Problems solved by technology

The solution period of this method is very long, and it only relies on the experience of professional engineers for heuristic exploration. Due to the limitation of brain computing power, it is impossible to fully consider the overall process planning level during the exploration process, usually limited to small-scale series connection, and finally If multiple steps are assembled and then connected in series as a whole, it is easy to fall into the dilemma of local optimization, and the solution accuracy of the process planning scheme is low.
