Virtual commissioning of robotic production system
Sláma, Martin ; Vetiška, Jan (referee) ; Bražina, Jakub (advisor)
The diploma thesis deals with the virtual commissioning of a robotic production system, which is located at the workshop of the Institute of Production Machines, Systems and Robotics BUT. The theoretical part of the thesis contains an overview of the current state of knowledge in the field of virtual commissioning and a description of the elements to achieve it. Next, the devices located in the specified robotic production cell are described. The practical part then describes the process of creating a simulation model in the program RobotStudio and its subsequent connection with the controlling PLC in TIA Portal via SIMIT and thus perform a virtual commissioning of the workplace.

Ceramic materials applied in medicine - challenges and opportunities
Vitásek, Ladislav ; Sláma, Martin (referee) ; Novotná, Lenka (advisor)
This thesis deals with ceramic materials applied in medicine, mainly in orthopaedics and dentistry. The first part is focused on requirements and current state of biomaterials in bone tissue engineering and their advantages and disadvantages. Composite materials, where ceramic material is one component at least, are mentioned in the next part. Dense ceramics based on alumina and toughened zirconia is described in the separate part. The main part of this thesis deals with porous ceramic materials based on calcium phosphates. There are also defined scaffolds requirements such as porosity, mechanical and biological properties and moreover processing methods. The experimental part of this thesis has been devoted to the preparation of bioactive porous ceramic material based on hydroxyapatite and silica with improved properties. Samples with different amount of silica in structure (6-21 wt%) were fabricated by polymer replica technique. Prepared scaffolds with structure similar to cancellous bone can be promising candidates for using in bone tissue engineering applications.

Study of preparation and properties of Ca-phosphates/ZrO2 biocomposites
Sláma, Martin ; Drdlík, Daniel (referee) ; Cihlář, Jaroslav (advisor)
The thesis was focused on preparation of bioceramic composite materials containing Ca-phosphates and zirconia fibers using electrophoretic deposition. A series of experiments were aimed at determining the appropriate composition of the suspensions. High-energy milling was used for preparing deposits with good physical and mechanical properties using EPD. The influence of milling time, the amount of monochloroacetic acid in isopropanol slurry indifferent electrolyte LiCl and ZrO2 were evaluated on the course deposition and the resulting properties of the deposits. Influence of sintering temperature, the milling time and the fiber content of ZrO2 on the chemical and structural composition was determined by X-ray analysis, measurement of density and structural analysis using a scanning electron microscope. Mechanical and bioactive properties of sintered deposits were determined depending on the milling time and content of ZrO2 fibers.

Preparation and properties of machinable ceramic materials
Sláma, Martin ; Matoušek, Aleš (referee) ; Cihlář, Jaroslav (advisor)
The thesis is focused on studying the machinability of ceramic material in dependence on presintering temperature. Alumina was used as an experimental material. The machinability of alumina was observed on samples produced by uniaxial pressing. Presintered and not-presintered disks were machined by cutter. Disks were presintered at 700°C, 800°C, 900°C and 1000°C for one or two hours. Machinability of alumina was tested according to four levels of the milled depth and according to temperature and the effect of dwell.
