Abstract

The present invention relates to a machining center tool decision making method for low-carbon manufacturing, which is applied to a single machining center manufacturing system. The method comprises the specific steps of: 1. determining the remaining life of each tool; 2. determining the available tool type and the corresponding cutting parameter for each work step of each workpiece; 3. calculating the processing time, processing power and tool wear rate of the available tool type for each work step in sequence, and obtaining a work step-tool type matching table; 4. using the multi-objective genetic algorithm considering tool life constraint to solve the problem, calculating the production cost and the carbon emission under different tool usage schemes and workpiece processing orders to obtain the optimal chromosome; 5. based on the optimal chromosome information, obtaining the processing tool of each work step and the loading tool set of each processing section, and putting them into production. The method according to the invention can make a quick decision on the choice and the loading order of the tools on the production site, generate the processing scheme where the cost and the carbon emission are optimized and coordinated, and guide the tool preparation and actual production.

Description

technical field [0001] The invention belongs to the technical field of low-carbon manufacturing and intelligent manufacturing, and in particular relates to a low-carbon manufacturing-oriented cutting tool decision-making method for a machining center. Background technique [0002] With the increasingly prominent problems of high energy consumption and high emissions in the manufacturing industry, low-carbon manufacturing has gradually attracted attention as the main direction of industrial transformation. The low-carbon manufacturing system includes many aspects such as product design methods, manufacturing and processing techniques, and parts recycling. The mechanical processing process is a key link in the manufacturing process, and the optimal use of energy and carbon emission control in the processing process is an indispensable part of the low-carbon manufacturing system. [0003] In the modern manufacturing process, the machining center greatly saves the time of the a...
