Diploma thesis deals with design and implementation of manufacturing technology of a part which was given by company Frentech Aerospace s.r.o. Manufacturing technology is prepared for conditions of workshop of Department of Machining FME Brno UT (laboratory C2). Acquired knowledges are used for design of innovative manufacturing technology with cutting tools from company Pramet Tools, s.r.o. Manufacturing technologies of gained part are designed for alloy blank EN AW 6082. Technical-economical assessment of all manufacturing technologies is part of this thesis. Both of manufacturing technologies designed for laboratory C2 are assessed together and manufacturing technology given by company Frentech Aerospace s.r.o. is assessed alone due to using different blank material.

The subject of this work is the repair of an air-handling unit. Possible causes of the problem are analyzed and multiple solutions are proposed. The first variant considers the refurbishment of the damaged component using thermal spray technology, including the choice of the best method. The second solution proposes the manufacture of a new part using machining in the environment of the company. This process requires an intermediate product to be made, and the choice of the correct machines from what the company has available, choice of the right tools and cutting conditions. The technical-economical evaluation compares the the expenses tied with both of the solutions. The chosen repair solution was used for the repair of the air-handling unit.

The main aim of this master's thesis is to propose a technological preparation of the wiping plate production. Elaboration is divided into four chapters. The first chapter describes forming tool (function and construction). In the second chapter is technologies overview, which are used for the wiping plate production. The most important is the third chapter, because it deals with the main output, and the actual proposal of technological preparation of the production. In the fourth chapter, production is reviewed economically.

The subject of submitted diploma thesis is complete structure of procedures necessary for the designing and subsequent production of forging dies for production of semi-finished connecting rods.

The dissertation is focused on the optimization of technological processes in the production of the outer bearing ring. The first part of the research was focused on the latest trends in the production of bearings. In the experimental part the technological processes of production were analyzed from the choice of the semi-finished product to the optimization of finishing technologies for machining the outer diameter of the bearing ring.

This diploma thesis is focused on piece production of the component and its subsequent assembly. It is an interchangeable spindle head marked VA1 from the product portfolio of TOS KUŘIM - OS, a.s. The aims of the diploma thesis include the characteristics of the assigned component, the subsequent analysis of the current manufacturing and assembly process. In the price calculations chapter, the direct and indirect input costs for the part production are quantified. Proposals to improve production were presented to the company and offered for possible implementation.

The aim of the thesis is focused on the proposal of a new technological procedure of the blade carrier for use in its own production. Currently, the carrier is manufactured by the German company B.Maier Zerkleinerungstechnik GmbH. The work includes several parts. The first part deals with the component itself, its function and importance, as well as its function in the assembly and the whole machine. In the next part the technological procedure of the blade carrier production is created. Fleet of machines including the necessary tools is also designed. In a separate chapter there is an economic evaluation of the proposed solution in two different variants, a subsequent evaluation and a proposal for implementation.
