Application of the SinuTrain 4.93 software in milling
Bartuněk, Martin ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
This diploma thesis is focused on the design and preparation of the production of a single front mountain bike chainring, using computer software SinuTrain 4.93. The work has several parts. The first part discusses the possibilities of NC programming and measurement. The next part deals with the design of a chainring, material selection and strength analysis. In the third part of the work, the technological conditions of milling are proposed and the machine is chosen. Next step is creation of NC program including inprocess measurement by workpiece probe and design of postprocess measurement by optical system SOL165. Finally, the work outputs obtained in the form of SinuTrain software simulation are evaluated.

Measurement of surface temperatures in mechanical engineering
Stránský, Marek ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
This work deals with contact and non-contact methods of surface temperature measurement. The work contains a list and formulations of basic terms and laws of thermodynamics. Furthermore, the work deals with the description and comparison of the properties and use of certain devices for contact and non-contact surface temperature measurement. The experimental part is focused on dependence of the turning speed on the turning knife thermal stress. Subsurface thermocouples, surface thermocouples and thermovision were used for the temperature detection. The subsurface temperatures were afterwards used (as data inputs) for the inverse calculation of surface temperatures. All results obtained were then compared to each other.

Technical preparation for the production of label carriers and RFID inlays
Blažek, David ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This bachelor thesis deals with the development and production of end effectors for the transmission of labels and RFID inlays using robots. The first part of it describes the RFID technology, robots and their end effectors, then compares the materials for the design of the end effector and its subsequent production. Then follows the preparation of a practical implementation, where the analyses examining the channels inside the effector are described. Furthermore, this work describes the testing of suction cups, production control by graphical simulation, production of individual prototypes of end effectors and their testing.

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.
