Design of internal MSA methodology in the company
Tesařová, Tereza ; Sámelová, Vendula (referee) ; Maradová, Karla (advisor)
The aim of the diploma thesis is to design suitable procedures for the internal MSA methodology, by means of which a company operating in the automotive industry determines the acceptability of a measurement system. The thesis contains a brief description and comparison of MSA, VDA 5 and ČSN ISO 22514-7 methodologies. It focuses in more detail on the evaluation of acceptability according to the MSA methodological manual. The tools for statistical data evaluation are also compared. The output of the work is an internal methodology with procedures for quantitative and qualitative data, with their analysis and statistical evaluation using selected software.

Sinumerik tools for programming of CNC machines
Kulenda, Martin ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The master’s thesis incorporates the control system Sinumerik 840D to the most widely used control systems of CNC machine tools. In the first thesis part are analyzed the NC programming methodics, which are relative only to the control system Sinumerik 840D and an essentials necessary to understand the issue in the area of CNC machine tools. Next part of the thesis includes design of the technology and processing of the NC program for machined component (gearbox cover). The NC program is made by ShopMill that is focused on a workshop area. During the program creation is combined a ShopMill and parametric programming, with using of a conditional jump instructions and repetitions. The final part of the thesis includes verification of the selected component production process by simulation and technical-economic evaluation of the designed technology.
