This thesis deals with the wear of indexable insert during machining railway axles in BONATRAS GROUP Inc. Thesis describes the technological process of this company and basic types of wear inserts. It also assesses the development of tool wear when cutting speed is increase by 10% and also to compare the wear inserts from different suppliers for that company. This work mainly deals with development of ridge wear of the cutting tool depending on the pressure of coolant.

The master´s thesis discuss about design and manufacture of blade stabilizer. It will be sets limit conditions for design blade and subsequent analysis of effects of stress and strain on the rod of blade and assembly of the stabilizer in various settings. For manufacturing of blade it will design materiál of the blank, manufacturing proces and machining conditions with the choice of cutting tools nad cutting machine. In conclusion will be comparison blades from formulas of last years from monopost Dragon 2 to Dragon 6.

The aim of this thesis is to propose a single-purpose stepped cutting tool for the drilling of the cylinder head. The thesis first introduces the current production of the cylinder head, including the description of the cutting conditions and the machines and tools used in the production process. The second part of the thesis is focused on the drilling of a three-step hole for which a step drill bit is proposed. The proposal describes the development of the drill bit, heat treatment, the method of clamping, the replaceable cutting tips used in the production process, additions for further machining and the cutting conditions. The last part of the thesis then deals with the technical-economic analysis, comparing the present and innovated stage of the production of the cylinder head.

This master thesis is dealing with the analysis of current technology of machining based on unconventional method of water jet cutting for sheet machining of composite materials. My goal is to analyze and calculate the cost of technologies. There is, in conclusion of the master thesis, the techno-economic evaluation and final decision whether it is appropriate to invest in a new technology or not.

Diploma thesis contains introduction of a company P-D Refractories CZ a. s., where the manufacture of ceramic chimney liners is. Followed by a description and analysis of the product in the entire production cycle, material and product spectrum. Based on the results of current production is created proposal to streamline the machining technology with a view to increase productivity and reduce defective products, which means determine the material of a tool and the method of machining. The work is finished by technical-economic assessment, where the summary and recommendation of the proposed solution are.

The theoretical study of this thesis deals with different approaches that can be used to optimize the topology of various structures. Main attributes and principles which they are based on of individual methods are discussed. The first point of the practical part is to design the model for computational analysis of stand and other machining centre parts based on real machine TOS FU. Afterwards, the model is analyzed to determine the dynamic characteristic of the machine. Subsequently, several changes of the stand design are performed in order to improve the dynamic behavior. Eventually, new stand kernel is designed which aims to enhance these dynamic characteristic. This model is analyzed again and the results are compared with the original form of the machining centre.

This master thesis Design of a machine tool for a safety keys production deals with concept of a machine tool for production of safety keys. Solution variants are methodically elaborated, mainly concerning their achieved tact times and machine dimensions. A computation diagram for fast comparison of concepts in case of different customer key specification is presented. Chosen concept version is then detailed designed. The result fills a hole on the market of specific machine tools for machining of safety keys.

This Master’s thesis deals with the proposal manufacturing technology of a shaft with gears on a CNC machine tool. The first part of the thesis is focused on the concise description selected shaft and its use. In the next part of the thesis are state selected materials, which are suitable used for shafts and gears. After that is create drawing component, suggest technological procedure, tool list and machine list which are suitable used for manufacturing selected shaft. In the final part of the thesis is create a CNC program for manufacturing the shaft on the turning and milling machine. Program is created in software SinuTrain 4.7 for control system Sinumerik 840D. The CNC program is verified by graphics simulation to determine a correct function

The objective of this diploma thesis was the design of a special machine tool that increases the efficiency of the production of a T-slot detail on the part of the clamp body. The thesis deals with the current production of this component as well as the description of the material, the machines that are used and the technological process. The next part focuses on the description of the new special machine tool, its production, heat treatment and the presentation of used indexable inserts. Another part analyses the production innovation that was comprised of the comparison with the former machine tool to the new one. The thesis concludes with a technical and economical evaluation of the former and innovated production.
