Abstract
Fixtures play an important role in the production of high-quality and competitive products, especially in the context of multiproduct manufacturing, which requires fast reequipment in the transition to the machining of parts of the other type. The article deals with the problem of determining the optimal dimensions of the fixture functional elements for machining of the lever-type parts within a given size group. The purpose of the research is to increase the efficiency of machining by optimizing the design of a flexible fixture through the proper choice of parameters of the fixture elements. Fixture configurations were analyzed by means of the parametric optimization algorithm. The reserves for fixture optimization were revealed, and possible variants of the fixtures for the limiting size of the levers within the given size group were investigated. Based on the research of static structural, modal, and harmonic analyses of fixture configurations, optimal parameters of each element of the flexible fixture were found out. The optimal design of the fixture is proposed, which can provide multiaxis machining of all sizes of levers within a given size group with the required accuracy.
