On the milling of ceramic materials
Rudel, Václav ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
In the diploma thesis dividing of ceramic materials is made, their bonds and other attributions, which define ceramic materials. There is also described how ceramic materials are manufactured and the thesis is including information about machining ceramic materials. In the experimental part sample of ceramic material R-S67K was machined by milling. During the experiment cutting forces were measured and roughness of surface after finishing, these data were finally evaluated.

On the milling of refractory ceramic materials
Reiter, Milan ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
Diploma thesis is focused on machining of refractory ceramics materials. The theoretical part describes the division of ceramics materials, their structure, manufacture and properties. This part also contains the division of refractory ceramics. In the second chapter, of ceramics materials are described machining. The latest chapter is focused on analyzing the machinability of ceramics materials R - SLI - K. During the experiment, cutting conditions were changed and cutting forces were checked. Then surface roughness was measured and tool wear was observed.

A study on the grinding of ceramic materials
Kresa, Jakub ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
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.

Simulation of cutting force during milling process with straight tooth plain milling cutter.
Zemčík, Tomáš ; Sedlák, Josef (referee) ; Zemčík, Oskar (advisor)
To make a simulation of cutting force during milling process with cilindrical cutter is the aim of this diploma thesis. Preliminary part is devoted to technology of milling, milling cutters and cutting materials. The next section is aimed at kinematics of the cutting process, a theoretical analysis of power proportion, the possibility of measurement of force actions. General information about the programming software, a theoretical simulation model, graphical environment of created application, are the other points of this diploma thesis. The work also includes evaluation of the experimentally measured values and compared with values obtained from the created application.

Cutting forces when drilling fibre reinforced composites
Režný, Tomáš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This master´s thesis is focused on fibre–filled composite materials, their distribution, labeling, usage, development and production. The aim of this work is complex processing of acquired technical knowledge, and evaluation of technological rehearsals of drilling composite materials which are reinforced by glas fiber and prepreg in terms of the impact of the machined material, wor-king conditions and the tool, and its wear to the feed force value and torque.

Cutting forces when milling fibre reinforced composites
Martének, Libor ; Forejt, Miloslav (referee) ; Humár, Anton (advisor)
The thesis is focused on composite materials with a view to their classifi-cation, identification, usage, current trends in production and development and possibilities of effective machining. As a part of this thesis, there is an evaluation of experimentally measured values during technological testing of milling of a fibre reinforced composite with a polyester matrix reinforced by fiberglass. The technological testing was performed with a view to measure certain values, i.e. impact on machined material, working conditions for a tool and its abrasion equal to the values of components of cutting force. From the values obtained from the testing, a general analysis of cutting force when milling was created containing overall technical and economical evaluation.

Simulation verify the dynamic behavior of the portal machine tool
Danda, Libor ; Holub, Michal (referee) ; Vetiška, Jan (advisor)
This bachelor thesis deals with summary of simulation software for the simulation of the dynamic behavior of machines, creating a simulation model of the machine in MSC.ADAMS and experimental measurement of cutting forces. It also deals with dynamics simulations axis motion and deformation analysis of selected components of the machine. Finally, they are designed to be structural adaptations in order to increase the dynamic stability of the machine.

Machining of titanium alloys
Kinc, Jiří ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This thesis describe titanium and titanium alloys from the perspective of charakter, production and use. Thesis gives information about difficulty connected with machining titanium by basic machining methods. Titanium alloy Ti6A14V was turned in practical part. Intention was to measure cutting force and specific cutting force.
