基于表面质量需求的机械零件再制造毛坯预处理工艺优化方法

针对目前再制造预处理工艺不能有效地与检测、修复等后续工艺相匹配的问题，通过调研现有再制造毛坯污染物及相应预处理工艺，构建了基于表面质量需求的再制造毛坯预处理工艺能力函数。同时考虑再制造预处理工艺中的能量消耗过程，构建了再制造预处理工艺模型，提出一种基于表面质量需求的再制造毛坯预处理工艺优化方法。以某款变速箱壳体类零件为研究对象，基于Box-behnken实验数据，构建了超声波清洗预处理工艺优化模型，并提出了不同表面质量需求下的优化工艺方案，验证了所提模型及方法的可行性与有效性。

Process Optimization Method of Core Pre-treatment for Mechanical Parts Based on Surface Quality Requirements in Remanufacturing

Aiming at the problems that the pre-treatment processes in current remanufacturing could not be effectively matched with the subsequent processes such as detection and repair, through the investigations of existing pollutions of cores and corresponding pre-treatment processes in remanufacturing, the functions of the pre-treatment process capability in remanufacturing were obtained based on surface quality requirements. Considering the energy consumptions, the remanufacturing pre-treatment process model was established and the optimization method of cores pre-treatment processes was proposed based on surface quality requirements in remanufacturing. The gearbox housing was taken as an example with Box-behnken experimental data, the optimized model was established in ultrasonic cleaning pre-treatment processes. And optimized process scheme was proposed to verify the feasibility and effectiveness of the proposed model and method under the different surface quality requirements.
