This diploma thesis focuses on the design of new technology for the production of a given part by company Poppe + Potthoff s.r.o. The thesis is divided into three parts. The first part is a theoretical analysis of individual operations that are necessary for the production of the given part. The second part deals with the analysis of the current technological process of production. In the third part, a new technological process is proposed. In the end, there is a technical and economic evaluation performed, where both variants are compared.

In terms of needs of practice, material slicing is one of the first operations at manufacture or fabrication. During the slicing process different conventional and non-conventional methods are used. Among the basic non-conventional methods is water jet cutting of two types: Abrasive Water Jet cutting (AWJ) and Water Jet Machining (WJM). This method is used in the technological process also for cutting devices of unique shapes and diverse materials

The aim of this thesis is the analysis of the current state in the workplace EDM and suggestion of the automation workplace in tool making "KASKO forms" including techno-economic assessment of the current and suggested solutions on the selected product and quantification of payback period.

This thesis deals primary with design of a woodworking machine focused on woodworking technology by cutting – rip saw. The introduction to the work is get to acquainted with the material to be processed – wood, and also the search of associated machines with the same technology of workpiece processing. Next part is focused on the safety of machining on woodworking machines and the individual safety features that the machines must contain are also analyzed. From this survey, a saw model with all the necessary features is created. The conclusion of the thesis is devoted to the risk analysis of the proposed machinery and their reduction.

The master’s thesis focuses on the machining of a chosen gearbox on a CNC machine. The theoretical part deals with gearboxes in general and the aluminium alloy from which a selected gearbox is manufactured. In the practical part, the machining of the gearbox is proposed according to the corresponding drawing. Gradually suitable machines are selected, then depending on their limits, clamping devices are designed, next a set of tools is selected and an NC program is generated. The technological process of production is proposed and the basic production costs are calculated.

The thesis is focused on the research on micro-milling with the aim to specify the latest findings and trends in milling and micro-milling. The introduction consists of the specification of micro-milling and its comparison with conventional milling. The main goal of the thesis is to interpret modern trends in micro-milling technology, such as machine modernization, advanced machining strategies and the latest CAD/CAM software. The second part deals with the influence of cutting parameters on the overall workpiece quality. The final part is devoted to the application and use of micro-milling technology.

Content of the thesis is the proposal of new technology using machining centres, including five controlled axis. Benefit of implementation the new nechnology is investigated at machining example, which is the gear housing of a single stage gearbox, manufactured in the company. In the first part of the thesis, the general properties of gearboxes and their housings are analyzed, as well as the procedure of the current proces of the machining representative. In practical part of the thesis is proposed necessary tool equipment and jig equipment, needed for machining of the part. After that are analyzed and filled in time studies, provided by manufacturers of machining centres. On the bases of these studies, were calculated operating times and operating costs per one piece of the housing. In the part of technical and economical evaluation is calculated the return of initial investment, including costs for byuing new machining cente and cutting tools equipment. Finaly are evaluated the overal benefits of the new technology, given the needs of the company.

Tato diplomová práce byla vypracována v průmyslovém kontextu, během stáže ve firmě Metso. Zlepšení obráběcího procesu zajišťovacích šroubů bylo cílem této práce, aby byla umožněna budoucí automatizace zakládání obrobku do stroje. Zlepšení bylo zhodnoceno na základě úrovně autonomie během obrábění, eliminace neprogramovaných zastavení stroje operátorem a dostačujícího odvodu třísek. Implementace automatických systému do číslicově řízeného obráběcího centra umožňuje zvýšení produktivity. Před automatizováním obráběcího procesu však musí být proces optimalizován. Zejména dostatečná fragmentace třísek a jejich evakuace jsou klíčové. Dlouhé nedělené třísky můžou poškodit systémy jako například automatický měnič nástrojů, dopravník třísek nebo průmyslového robota. Dostatečná lámavost třísek může být zaručena správným výběrem technologie a strategie obrábění, výběrem řezného nástroje a řezných podmínek pro daný materiál obrobku.

My thesis is aimed at the application of wire electical discharge machining technology in the production of woodworking tools. All of this in the conditions of Vydona company. There is a theory of machining method plus a well-aranged division of cutter tools for wood in the introduction. The practical part describes in detail the procedur of cutting shaped plate out of tungsten carbide. As a result of the technical and at the same time the economic evaluation is an establishment of hourly rate for machine.

This eleborate study is aimed at analysis of complete methods machining. There are characterized particular methods and their effect on the surface´s quality of machined area in this study. Concluding part of the study includes practical demonstration of machining by using cemented carbide-tipped tool and polycrystalline diamond and evaluation of this demonstration.
