Optimization model of the processing parameters for structural elements of a product

Optimization of the target indicators of the technological process is a key factor in increasing the efficiency of the product manufacturing process. The efficiency of the optimization process directly depends on the degree of detail of the control object. The purpose of the study is to increase the efficiency of the process of forming individual geometric elements of a part through multi-criteria optimization of the technological process parameters. The paper presents a structural hierarchical model of optimizing the parameters of the process of forming a geometric element. This model is a structural decomposition of the goals to be achieved within the identified control level. Based on the structural decomposition, four levels of process control are identified. This hierarchy of goals allows increasing the efficiency of the geometric element formation process through detailed analysis and optimization of target indicators at each stage of the process. The paper considers an example of optimization of the process parameters for machining a group of threaded holes M27x2-6H in a product made of dispersion-hardened composite alloy SAS-50. Optimum values of the process parameters for each forming stage are determined for the investigated group of holes according to the structural model of the process. As a result of optimizing the process parameters, the accuracy of manufacturing a group of threaded holes increased by 22.2%, while the labor intensity increased by 13.69%.
