Tato diplomová práce se zabývá modifikací původního tvaru součásti za účelem co nejlepšího splnění provozních podmínek daného zatížení a omezujících podmínek v programech M.S.C. NASTRAN, M.S.C. PATRAN a FUSION 360. Součást je připevněna na ortotropní desce (sendvičovém panelu). Cílem této práce je zjištění efektu elastického podkladu na výsledky optimalizace. Součást bude optimalizována za použití různých cílových funkcí a omezení. Elastický podklad změní tuhost, což může změnit napěťový stav součásti. Únosnost původního a modifikovaného tvaru bude srovnána pomocí programu M.S.C NASTRAN/PATRAN. Po tvarové optimalizaci má být 3D model připravený pro výrobní proces, který bude cenově nejefektivnější.

The diploma thesis deals with the influence of machining technologies (turning, milling, grinding and polishing) on the surface texture of functional surfaces of selected materials from technical plastics. In the first part of the thesis there is a theoretical analysis of the possibilities of machining plastic materials. Furthermore, an analysis of the most commonly used parameters for evaluating the roughness of the machined surface and their effect on functionality is performed. The experimental part of the thesis describes samples preparation, analysis of measured data and subsequent evaluation with benefits for machinery industry.

Work is focused on theoretic analisis of manufacturing precise shears tools by unconventional technology closely focused on wire electro discharge machining consideration operation costs of this metod.It is discribing development of this method, machines and tools for electrical discharge machining. It is mention facts influencing quality of cut surface during manufacturing of cutting tools, strategy of cutting workpiece, stage and quality of surface layer after WEDM as long with economic viewpoint and benefits of WEDM technology.

In diploma thesis there is elaborated the analysis of assumed development of water jet technology and there is analyzed the level of water jet method in production. There are introduced the possibilities of new applications of water jet machining and the possibilities of it’s future development. There is think over the enlargement of this method in next 5 years. Simultaneously there is solved the question of techno economic operation severity of this technology.

The aim of this thesis is shortening of standard mechanical time of work piece from aluminium casting alloy. . The shortening can be reached by linear programming of cutting conditions of cutting conditions during machining holes. This method is defined both theoretically and is applied to given setting and by the calculation by the Simplex method. Another method is exchange of tools at machined threads, it’s exchange of used tools for the new one, that makes more operations at a time. The result is shortening of mechanical time, augmentation of productive dose, capacities of workplace and productivity work.

Objective graduation theses, is determining and propound optimal alternate manufacturing section servant as base of electron microscope. As a production method is used chippy cutting on numerical controlled machine behind by the help of usage progressive cutting tools. To construction control program was use 3D CAD/CAM system of Solid Vision, Ltd. Corporation. Product working is complete project and procedure on manufacturing section, that is in finish well-founded technoeconomic evaluation.

The objective of this diploma thesis are new design materials in a view of their structure, properties, manufacture,partitions, applications and possibili-ties of effective machining them Ceramics are used in the field of design applications more often than before. They are in form of compact parts and in form of thin coatings on the surface of metal parts. Fast development of constructive applications requires the same progress rate of machining ma-chines innovations and development of new methods of effective machining these materials, too. The aim is to produce parts of demanded shapes, dimensions and surface quality at affordable costs. Ceramics guarantee long terming durability and reliability. The evaluation of ceramics grinding tests from the point of view of cutting forces and surface quality of the machined faces are presented in the last part of the diploma thesis.

The aim of the thesis is to design, conduct and assess an experiment seeking to look into the utility properties of recent tools manufactured by HAM-FINAL. The tools include polycrystalline diamond (PCD) and CVD diamond cutting edges. In the theoretical part, the attention is devoted to cutting materials with an emphasis on diamond materials, as well as to issues associated with the wearing of the cutting tools, requirements specified for precision of bores and tools used in the manufacture of precision bores. The paper further provides an overview of a selection of world’s leading manufacturers of PCD blanks, CVD diamond coatings, CVD diamond layers and reamers with PCD cutting edges.

Proposal progressive technology of production shearing tools. Description shearing tools and shear of the process, analysis current technology production shearing tools. Proposition two variant technology production given to dies method conventional and unconventional, elaboration technological progress and programmes on choice NC machinery, their comparison and technical economic evaluation in fine with recommendation for usage practically.

This master´s thesis focuses on the basic principles of the nonconventional technology of electrical discharge machining (EDM) with an emphasis on wire-cut electrical discharge machining performed in a mediumsized company. The thesis deals with manufacture of a belt pulley 75-8M-130, and checks of accuracy of wire-cut EDM machines. Following the study of the current status of electrical discharge machining in the engineering company, measures for assurance and increase of accuracy of wire-cut EDM machines are proposed.
