Abstract

The presented dissertation primarily deals with the idea that leads to the improvement of the quality and efficiency of machining at the Innomotics Elektromotory s.r.o. plant, a branch plant of Mohelnice, due to the lower weight of the clamping jaws, and therefore the entire rotary system (workpiece + clamps), for machining passive parts of the electric motor. This can be achieved in several ways, such as changing the design of the clamping fixtures or changing the material of the clamping fixtures. Changing the design means using topological optimization or reverse engineering, with the help of which it is possible to accurately determine the limiting forces and dimensions, and in this way save several percent of unnecessary material. However, if we added a change in material to the change in design and used modern composites or special alloys, we would get a mixture of the best properties that the given clamping fixtures can have in an industrial environment. This is exactly the system that this dissertation was created with and the main idea was not only about the design of such a functional system, but also about testing it in practice. Secondary, it also deals with the application of topological optimization and reverse engineering. This whole idea and effort for change stems from the higher demands for competitiveness of the 21st century in the field of electric motor production. The main idea is the involvement of industry 4.0, which also includes additive technology - 3D printing, which opens up further possibilities for the production and processing of fixtures and all types of fixtures. 3D printing is also widely used in the Mohelnice plant in the automation of workplaces and robotic cells, mainly due to the very short production and delivery times. The entire work is divided into two basic blocks. The first block is a theoretical introduction to the issue of 3D printing, the use of various types of technologies, differing based on the application of use, type of material, but also the principle of further use. Furthermore, the first block discusses the principles of 3D printing, the complexity of this technology and, last but not least, possible defects that can cause the production of scrap or damage the production technology. The second block opens with the experiment itself, which verified the possibilities of changing the material, applying topological optimization and finally verifying the entire system in practice. The result was clamping elements that, theoretically, but also practically, should be functional, lighter, cheaper and perhaps even stronger than classic clamping elements designed and manufactured with the support of standard conventional tools, thinking and technologies.
