The aim of my work is the rationalization of an elektroerosive process of sinking during the production of a die in a given firm on a sinking machine Agie Hyperspark 3HS. This machine was compared with an existing device in Kovolit Modřice, a publicly held company. And subsequently it was tried several variations of setting. Afterwards it was chosen the most optimal setting for consecutive production of concrete die.

This master’s thesis familiarizes reader with technology of machine grinding – it’s history, principle, general use, related tools, achievable parameters and kinematics of grinding process. The core of work is analysis of jig-grinder Hauser H45-400, it’s kinematics, machine technical data, options and accessories. Work concludes with technical and economical assessment of machining of several parts with this machine and compares results to alternative options of machining.

The aim of this master's thesis is experimental electric discharge sinking of special materials for the aerospace industry. The first part is a general overview regarding the technology of electric discharge machining with emphasis on electric discharge sinking. Following this is a practical part devoted to the electric discharge sinking of the Nimonic 263 material with a copper tool electrode with a subsequent evaluation of surface and subsurface changes in this material. The wear of the tool electrode is also examined with the conclusion highlighting combination of machined material and tool electrode material behave in different working conditions and how the surface layer of machined material is affected.

This master´s thesis deals with the issues of electroerosive machining material used in aerospace industry. The master´s thesis is divided into the theoretical and practical part. In the theoretical part is described electroerosive machining with a focus on electrical discharge sinking. One section of the theoretical part is an analysis of materials used in the aerospace industry. The practical part of the master´s thesis is focused on electrical discharge sinking of aerospace material INCO 713LC, here is investigated the influence of machining parameters on the surface of the workpiece and tool.

This diploma thesis view to problem electrical discharge sinking. Forth with deal production of indexable insert cemented carbide and application electrical discharge sinking at this technology.

In this work, a principle of Electro Discharge Sinking Technology is described as well as comparison of individual machine producers. Further, description of an electrode production technology is included together with a recommendation of a machine to a middle mechanical engineering company. Last part is dedicate technical and economical analysis on concrete types of machines and adumbration another trends of development.

In the introductory part of the work carried out the theoretical research of advanced methods of cutting. Chosen methods are laser, water jet and EDM wire cutting and trenching the wire. There is described the history, the principle of separation and classification. The practical part of these methods are discussed in detail with emphasis on their use in practice. The text is supplemented with illustrative examples of products. Finally, the work focuses on the comparison of the described methods. Overall, the work is conceived as a methodological text useful in teaching this topic.

The master’s thesis deals with the topic of electrical discharge machining. The first part of the thesis contains a study of the die-sinking EDM. The die-sinking EDM of the silicon carbide ceramic is realized in the experimental part of the thesis. The result of this work was to explore the influence of the EDM sinking parameters, specifically pulse current, open-voltage and pulse on-time, on the machined surface. Furthermore, the analysis of the tool electrode was made. This analysis was focused on the wear in the corners, which has key influence on accuracy of the machining. The machining time was also examined.

In this work, description of a basic principle of electro discharge machining and its technological possibilities was made. Possibilities of individual EDM machine producers and their comparison were described. Furthermore, the use of electro discharge machining in Zdas a.s. was shown. Trends in a development of the electro discharge technology are included, too.
