Abstract

The invention discloses a hobbing parameter solving method based on a multi-target Harris tenon optimizer. The hobbing parameter solving method comprises the following steps: (1) realizing the multi-target Harris tenon optimizer; (2) establishing a hobbing parameter comprehensive model by taking carbon emission, cutting time and cost as targets; and (3) solving the hobbing parameter comprehensivemodel based on the multi-target Harris tenon optimizer. The method has the advantages that the multi-objective Harris tenon optimizer is proposed for the first time, a Pareto improvement method is fused into Harris tenon single-objective optimization, the multi-objective Harris tenon optimizer is generated, the application range is wider, and the performance is more excellent; 2, hobbing parameters and targets are improved at the same time, specifically, the hobbing parameters are continuously optimized through a multi-target Harris tenon optimizer, so that the hobbing parameters reach an approximately optimal state, and the cutting time, cost and carbon emission are minimized as much as possible; therefore, the problems that hobbing parameter selection is conservative and new requirementsof carbon emission are difficult to meet are solved.

Description

technical field [0001] The invention relates to a method for solving gear hobbing parameters based on a multi-objective Harris Falcon optimizer, and belongs to the technical field of gear processing. Background technique [0002] In the actual gear hobbing process, technicians are faced with a variety of new process parameter selection problems. According to the processing requirements, they often choose more conservative process parameters. On the one hand, it is difficult to give full play to the performance of the gear hobbing machine itself; Process parameters are time-consuming and error-prone, which has a significant impact on production efficiency, cost, and carbon emissions. [0003] In China, there are few studies on the solution of process parameters in the process of gear hobbing, and there are even fewer solutions to solve hobbing parameters under the new target of carbon emission in addition to the traditional cutting time and cost targets. Therefore, it is nov...
