The aim of the thesis is to analyze the production costs and optimize cutting conditions for high-feed face milling of titanium alloy Ti6Al4V. In the experiment were changed cutting conditions, such as cutting speed vc and feed speed vf. During the experiment were checked cutting forces by dynamometr. Furthermore, surface roughness and tool wear is observed.

This diploma thesis deals with a design of the simulation model of a CNC machine tool for determining the energy consumption. It describes a design of the mechanical and the electrical model of the CNC machine and a design of the energy consumption algorithm. The result of that thesis is a size of the consummated energy during a machining process.

This thesis will focus on a design of multifunctional machining center. The work is created in cooperation with two colleagues. Michal Kunorza will design a rotary table and Tomáš Grëtz will design a machine spindle with automatic tool exchange. My part of the work will focus on design of linear tool axis. The result of this cooperation should be machining center for rotary and non-rotary workpieces.

This thesis is focused on ceramics materials in terms of their partition, properties, structure, manufacture and methods of their possible machining. The first part of this thesis is devoted to the distribution of ceramics materials, their structure, properties, and methods of production. Currently, ceramics materials are increasingly used in structural (engineering) applications therefore we deal with methods of effective machining of ceramic materials, to achieve part of the required shape, dimensions and surface quality. The evaluation of ceramic grinding test from the point of view of cutting forces and surface quality of the machined faces are presented in the last part of the thesis. The tested materials have been provided by company SEEIF Ceramics a.s.

The diploma thesis Rationalization technology of production tools is divided into two parts. The first part is focused on injection molding of plastic materials and analysis current status of production injection tools. The second part contains proposal of rationalization steps in the production process and evaluation of rationalization.

This thesis deals with manufacturing process of a front wheel hub carrier prototype for formula TU Brno Racing Dragon 5 series. The paper starts on foregoing work of design team leading to a proposed model and material. Both material and model are investigated form a manufacturing point of view. Cutting conditions and milling strategy are proposed based on final product analysis. Prototype was manufactured on CNC machining centre MCV 754 QUICK in company BOSCH DIESEL s.r.o. in Jihlava. Retrospective analysis of performed manufacturing process and critical risks is provided with a proposal of more effective manufacturing process. In the closure, there is technical-economical evaluation of chosen manufacture done by milling. Alternative manufacturing options including 3D print and welding are compared in technics and costs.

This master’s thesis deals with an influence of physical properties and machining technology at adjustment to the basic composition granules and production of technical ceramics. Selected series of experiments have been applied to the different phases of production. Composition of the granules vary according to the used plasticizer and ranks to RTP (ready-to-press) materials. The goal of this thesis is recomendation to the production of RTP granules and next experiments.

This thesis describes the design of methodology for measuring the accuracy of robot machining. It describes the theoretical properties and classification of commercially available methods for precision measurement. In the practical part, a test workpiece is manufactured and positions and toolpaths are measured by the Pontos system. The proposals are based on the MCAE Systems company's equipment.

The objectives for this dissertation are to push forward the current state of knowledge in the area of machining fiber-reinforced plastic (FRP). The most common machining operation performed on these materials is drilling owing to the need for component assembly in mechanical pieces and structures. Among the defects caused by drilling, delamination appears as to be of the most critical and may occur at both the entrance and exit plane. A number of theoretical and experimental studies have been made to create an analytical model of delamination in composite laminates. In this dissertation, the critical thrust force (force which initiates the delamination) is predicted using linear elastic fracture mechanics - assuming Mode I. Delamination is investigated by studying the evolution of feed force and torque applied by the tool on the workpiece. A four components piezoelectric dynamometer KISTLER 9272 with special PC-software is used for measuring and evaluating of torque and cutting forces, when drilling two different composite materials: carbon/epoxy laminate fabricated by hand lay-up technique and glass/polyester composite made by pultrusion. Wear mechanisms and location of the wear on the tool are also investigated (with respect to cutting material). The tool wear is measured with help of a common workshop microscope and recorded with scanning electron microscope PHILIPS XL30. Drilling experiments are performed to give complex technical information (i.e. cutting conditions, tool geometry, tool wear and so on) which enables efficient machining of composite materials. Delamination-free drilling is given special emphasis in the experiments. Methods of statistical analysis (DOE) are used to determine which factors have the most influence on delamination.

The dissertation is focused on streamlining production on wire electric discharge machine during cutting metal alloys, specifically low-alloy steel quality by CSN 41 4220. The first part contains a study of the current and modern technologies EDM wire cutting. The second part is focused on identifying key parameters to influence the WEDM process, a detailed analysis of the machined surfaces of samples and wire electrodes used for cutting. The result of this work was to explore the possibility, whether by performing planned experiment and subsequent evaluation in the future to determine exactly setting the key parameters influencing the process of WEDM.
