The topic of this thesis is the choice of optimal production technology for the chosen representative. The aim of this work is to compare production on conventional machine and on NC and CNC machines. Both variants are evaluated in terms of efficiency, speed and economy of production. Outputs are based on recommended production procedures based on the number of pieces produced in the order.

This master thesis focuses on analysing the origins of residual stress in material caused by face milling. Representatives of three groups of aluminum alloys (5000, 6000, 7000) are compared by measurements. For measuring of the residual stress in aluminum alloys, the hole-drilling method was used by applying tensometric rosettes. In order to determine the influence of the used milling cutters', flatness of the machined surface was analyzed by comparative method. The thesis concludes with a discussion and an overall evaluation of the results.

This master's thesis deals with the process of machining a forged connecting rod in cooperation with the company Zetor Tractors a.s. The first chapter of the thesis is focused on a detailed introduction of the company. The second chapter includes an elaborate analysis of the technical documentation and requirements concerning the making process of the subject of study, specifically the construction of the connecting rod. In the third chapter, the current production technology is discussed and described in detail. The aim of the fourth chapter is to propose an innovative technology which can be used for the production of connecting rods in the required quality. The fifth chapter is aimed at testing the newly designed technology. In the final, sixth, chapter, a technical and economical evaluation of the proposed procedure is performed.

The meaning of the diploma thesis is to create a new mold plunger for injection mold using a suitable method according to the original mold plunger. The final mold part should meet the required surface parameters. The work is focused on the analysis of the original mold plunger and the experimental verification of suitable methods of production of the equivalent mold plunger.

The assigned thesis is focused on the proposal of rationalization solutions to the component Bonnet, which is a standard representative of the most important sections of broader spectrum of customer´s components. The introduction part describes the component basis, according to which the standard representative was chosen, later on characterised from the point of view of seriality. The following large part of classfying the time comsumption in machinery is essential for the calculations as such, which are the essential part of this dissertation. The proposal of production rationalization is concerned with the exclusion of unnecessary losses and using existing ressources with the help of a higher level of machinery, technology, work organisation, production and management, which lead to a higher labour productivity. The technological production preparation ensures the documentation processing, the proposal of semi-finished product, machines, fastening, measuring and calculation of necessary technological specifications for ensuring the production. In the final part, there is to be found the technical and economical evaluation of rationalization proposals, which numerically evaluates the analysed outputs of this thesis.

This work is focused on the software compensation of the geometric and volumetric errors. In the thesis there are descripted the measuring instruments suitable for measuring geometric and volumetric errors of the machine tool. In addition, there are described control systems and selected software compensations currently used in the machine tools. In the experimental part of the thesis there is briefly described the machining machine where the experiment was performed. Detailed procedures for using the used measuring instruments are also described. The aim of this thesis is to determine the influence of the size of the compensated volume on the geometric and volumetric precision of the machine tool.

The master thesis deals mainly with the optimization of machining of ceramic semi-finished products from ZrO2 and Al2O3. The first part with literary research, which describes the steps of the technology of forming ceramic bodies, especially the gelcasting method. The thesis describes possibilities of milling of ceramic materials using CNC technology. The thesis describes the dependence of acquired roughness on bodies and used machining strategies. The best roughness parameters on ZrO2 samples were obtained after they were calcined at 900 ° C, while the lowest roughness was obtained on the samples in the unprotected state for the Al2O3 samples. Samples machined with a spherical milling cutter showed surface roughness Ra = 1 m for ZrO2 and Ra = 1.3 m for Al2O3. It also describes the possibility of machining sharp-edged shapes and fine details where the best results are achieved on ZrO2 samples engraved at 900 and 1100 °C. Tool wear was particularly important when machining samples of Al2O3 ignited at temperatures above 800 °C.

Diploma thesis deals with renovation of tractor Zetor 6911 with hand tool machining use. Theoretical part aims at historical evolution of machining and describes the hand tool machining methods. Renovation options include repair by a renovation company, yourself renovation and yourself renovation with cooperation in external company. Due to great renovation experience and technical knowledge is tractor chosen to be renovated by yourself. Complete machine renovation is very complex thus there are shown only specified examples of machine parts renovation. In the thesis there are in detail described renovation processes, including tools and hand devices. Final part includes results evaluation and costs comparation of renovation options.

The diploma thesis presents a design of a technical project: design of production technology for a pinion shaft of a gearbox and design of alternative technology. It focuses on the analysis of a component, the selection of materials, machines and tools, and the creation of a manufacturing drawing and technological process of the production. It is concluded by a technical-economic evaluation, based on which are both designs compared and evaluated which design is better for specific conditions.

The main topic of this Master thesis is proposal of the streamline the production of the machined part of a handguard. The aim of the work is to evaluate the current machining process, to design possible innovation, to select the best way of construction of a design part. The conclusion will be devoted technical and economic evaluation in terms of time, cost and material consumption.
