Sinumerik 840D tools for programming of CNC machines
Olina, Anna ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
Master’s thesis presents the history and the present-day state of CNC machines and their control systems. This thesis describes both the basics and the advanced methods of programming which can provide the ability to create NC program for Sinumerik 840D to operate. The second part of the thesis deals with the development of the technology to machine the part (the frame of the reduction gear) and corresponding NC program. This program is created by means of the work-step programming (ShopMill). The final verification of the program was provided by means of simulation component of the control system.

Sinumerik tools for programming of CNC machine tool
Chytil, Tomáš ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The bachelor thesis focuses on the usage of possible ways of the Sinumerik system for programming of the form of the drop forging. The first part of the thesis contains of the characteristics of the part and its function in the composition. In the second part there is all the proper visual documentation. The following parts of this piece of work is devoted to the history and specification of the Sinumerik control system and a suggestion on how to make a forging die.The next part is contributed to the possible ways of how to produce a form in the Sinumerik system. The final part deals with the very formation of the programme and its graphic simulation.

Prototype Part Design Using the Reverse Engineering Technology and Rapid Prototyping
Luňák, Václav ; Sámelová, Vendula (referee) ; Slaný, Martin (advisor)
This Bachelor thesis is dealing with the manufacturing process of a motorcycle turn signal part using the technologies of reverse engineering and rapid prototyping. The thesis contains a brief description of the available technological methods. The following chapters deal with designing the component and its preparation for casting. The component is manufactured using the FDM method. The quality check is performed by the ATOS 3D scanner, which compares the newly manufactured component to the original part. The next step is the preparation of a silicone mold, which is used to cast more parts. Finally, the cost-effectiveness of this method is compared to the method using metal molds.

Design of a measuring equipment for distance sensors calibration
Zindler, Lukáš ; Sámelová, Vendula (referee) ; Štěpánek, Vojtěch (advisor)
This study aimed deals with the design of a calibration equipment for an inductive distance sensor. The theoretical part provides a basic overview of metrology and the state of knowledge in the field of sensors. In the practical part, several concepts of measuring equipment are suggested, a suitable calibration equipment is selected and assembled, and at last the compensation of the systematic error of the sensor is performed.

SinuTrain Operate 2.6 tools for programming of CNC machine tools
Švagera, Pavel ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The master´s thesis demonstrates the SinuTrain Operate 2.6 tools for programming of CNC machine tools. In the first part is done integrating the control system Sinumerik 840D to the most widely used control systems of CNC machine tools and described NC programming methods. The next part of the thesis involves the preparation of technical documentation machined component (front hub on a bicycle) and production design created by using ISCAR company tools. The final part of the thesis is dedicated to creating the NC program and verification of simulation.

3D Scanning System Proposal for Plastic Parts
Palátová, Zuzana ; Jankových, Róbert (referee) ; Sámelová, Vendula (advisor)
The diploma thesis is focused on monitoring and description of the current state of plastic injection molding production and analysis of methods for measuring these parts. Measurement methods are described and at the same time the measurement issues associated with individual types of meters for specific plastic parts are presented. Based on the analysis of measuring systems, a design of the measuring device in the form of a 3D optical scan is subsequently created, which is optimal for the selected plastic components. When choosing a 3D optical scanner, a demand is created that takes into account the necessary technical parameters required by the corporate environment. A selected proposal is presented at the end of my work.

Design of the process of input control of deliveries in the company
Ondřejová, Kateřina ; Sámelová, Vendula (referee) ; Maradová, Karla (advisor)
The thesis analyzes the current state of the process of incoming inspection in the company. It describes the current state of the process in the company and subsequent processes that are part of the whole organization. The thesis uses the PDCA methodology to define the weak points in the measurement system, which are parts of entry control. Furthermore, it will explain how tools and their applications are used to improve the measurement system the follow-up of the incoming inspection. Ultimately I would like to avoid an increase in low quality parts in the incoming inspection process. By implementing the defined methodologies, the data can be considered eligible and can be subsequently presented throughout the whole process.

Evaluation of Surface Texture Profile Parameters and Verifying of Conformity with the Specification in the Drawing
Kupský, David ; Jankových, Róbert (referee) ; Sámelová, Vendula (advisor)
The first part of the thesis is devoted to the development of the current state of knowledge in the field of surface texture assessment using the profile method. The next part is the analysis of the problem and the proposal of a solution for the evaluation of surface texture with the consideration of measurement uncertainties in accordance with the ISO GPS system. Proposal of measurement and evaluation of the given sample was carried out for the demonstration. The measurement was started using a contact profilometer and then the profile parameters were calculated in the TalyProfile Lite software. Three different specifications were chosen for the calculated geometric parameters to outline all the possibilities that can arise when determining compliance with the specification. The proposal with consideration of uncertainties was compared with the evaluation method according to ČSN EN 4288 and from that were deducated conclusions and recommendations.
