“…In the process of optimization, the most rational research method is the use and variation of not all parameters at the same time, but only those that have a significant impact on changing the criteria of interest, in particular, design elements of the structure [8]. Obtaining the necessary data assumes the presence of a mathematical model of the development object, which can unambiguously express the dependence of the output parameters Y when changing control objects -parameters X.…”

Modern manufacturers of multipurpose machining centers design and manufacture equipment according to the criterion of maximum rigidity and productivity to ensure processing of the maximum range of materials at high accelerated cutting modes. As a result, in most machine-building tasks, the support structure of the machine is unnecessarily rigid due to the production of excessively massive frames and body elements of the machine. These structural elements have high weight and size characteristics, which leads to an increase in inertial loads on the drive feed mechanisms. In serial and mass production, heavy elements of the support structure significantly increase the energy consumption of the machine, while reducing labor productivity. Modern methods of design optimization, together with finite element methods, allow solving the problem of energy efficiency and productivity by modifying the support structures according to the criterion of minimum rigidity in accordance with the boundary conditions of the cutting forces when processing the selected product range.

For excellent damping properties, polymer composite (PC) has drawn particular attention in the field of modern ultra‐precision machining (UPM). However, applications of PC are restricted due to its inferior mechanical strength. In this paper, different granite coarse aggregate, different fine aggregate, and different filler were added into PC to increase its mechanical strength. The effects of coarse aggregate type, fine aggregate type, filler type on the mechanical strength of particle‐filled polymer composite (PFPC) were investigated systematically. Experimental results show that the best mechanical strength was obtained when the coarse aggregate type is Jinan clay granite, the fine aggregate is Jinan clay granite, and the filler is fly ash (FA). Results also show that the compressive strength of PFPC was closely correlated with the compressive strength of aggregate rock, and the compressive strength of PFPC increases with the increasing compressive strength of the aggregate rock. In order to further improve the mechanical strength of PFPC, the aggregate was subsequently treated by ultrasonication, direct mixing silanization, nebulizing silanization, macerating silanization. And four types of PFPC were obtained, that is, U‐PFPC, D‐PFPC, N‐PFPC, M‐PFPC, respectively. Among these four types of PFPC, the M‐PFPC exhibited the best mechanical strength. And the compressive strength and flexural strength of M‐PFPC are 146.97 MPa and 37.33 MPa, respectively; increased by 8.31% and 13.53% compared with PFPC produced by standard pouring technologies. In addition, the mechanism of the influence of the aggregate whose surfaces were treated on the mechanical strength of PFPC was revealed by scanning electron microscopy and contact angle test. The test results show that the M‐PFPC exhibited the favorable interface bond. This study was of great significance to increase the mechanical properties of PC and improve its application in precision machine tools.
