Implementation of SPC into the manufacturing process
Simandl, Martin ; Nikodým, Lukáš (referee) ; Bartes, František (advisor)
The diploma thesis focuses on the introduction of statistical process control in selected manufacturing company XYZ. It is divided into a theoretical and a practical part, while the theoretical part deals with theoretical knowledge of SPC methodology and quality management. The content of the practical part is the design and implementation of the measuring and evaluation station, which will be used for statistical control of the SPC process, into the emerging production of chip machining.

Production of flanges using the procedure PPAP , and ISO 9001
Prokeš, Tomáš ; Zahradníček, Radim (referee) ; Mouralová, Kateřina (advisor)
In the first part of this thesis is described implementation of quality management system in a small company according to ISO 9001. Next part is about production process by method PPAP. In this section is solved primarily ISO 9001 standard, statistical control of production and certification company according to requirements of ISO 9001. Second part is focused on mass production of flange by using the company facilities Kovobrábění Sobotka. In the end of thesis are reflected weaknesses of production. In the conclusion is described technical and economic evaluation of implementation QMS and machining sample parts.

Design of inspection procedure for selected revolver components
Úlehlová, Eva ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The goal of this master’s thesis was design of the inspection procedure for hammer and trigger of the specific revolver model. Thesis was developed in cooperation with the manufacturer of the revolvers. The theoretical part deals with the MSA methodology, which is used to assess acceptability of measurement systems. The practical part describes the current measurement system and performs gage repeatability and reproducibility study. It was confirmed that the current measurement system requires improvement. Subsequently coordinate systems were designed, based on functional features of the hammer and trigger. Automated optical measurements, based on the coordinate systems, were performed. The results from these measurements were again assessed by the gage R&R study. The analysis confirmed improvement of acceptability of the designed measurement systems. Based on these results, it is recommended to apply suggested procedures in practice. Results and recommendations of this master’s thesis can contribute to develop metrology in the company and improve the existing measurement system.

Repeatable Torque Load Equipment Design for Vehicle Steering System Testing
Novák, Pavel ; Ludvík, Jan (referee) ; Ramík, Pavel (advisor)
The object of this work is design braking device with high repeatability and reproducibility that is used to analyse the measurement system. I developed this work in cooperation with TRW-DAS Dačice a.s. At the beginning, I made a search of the chassis system, testing of ball joints and steering. Furthermore, I made search of the MSA and the types of braking devices. The rest of the work is focused on the design and the thermal analysis of braking device. Then there are the actual test.

VC5 and Vision Designer platform visual system
Popovský, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
For the purpose of an future machine vision system development in Tyco Electronics Czech s.r.o. I have developed Cognex Designer template. Template will serve as a flexible basis for further development of camera applications on the Cognex VC5 industrial computer. The functionality of the program template has been successfully verified by modifying it to a particular application of the laboratory manual station used to measure the parameters of the manufactured connectors. A camera with lens and lightning was chosen and installed on the station. DIO communication was put into operation between VC5 and PLC system. The application has been calibrated and verified as a measurement system using MSA Type I and Capability study standard methods.

Assessment of the process stability
Kostečka, Petr ; Bednář, Josef (referee) ; Kotek, Luboš (advisor)
This master`s thesis is focused on the application of statistic process control in engineering production and it is focused on comparison with method Beta correction. The aim of the diploma thesis is to find suitable regulation of the producing process with respect to provision of sufficiently high level of quality of products at the process of achievement of adequate costs conneced with process monitoring. The basic principles of both methods are solved in the theoretical part of this diploma thesis. Both methods are compared in particular producing process in the practical part of the thesis. Conclusions and suggestions are done on the base of gained data.

Analysis of process for production of small plates
Talanda, Jiří ; Fiala, Alois (referee) ; Koška, Petr (advisor)
Theme of the Master’s thesis is analysis of process for production of small plates. Main parts of the thesis are analysis of the production process, process mapping, data capture, analysis of the data by Pareto analysis and find causes of nonconformities. Causes analysis is based on data analysis and process observation. It is divided to chapters by factors which are influencing the process. Optimization measures are designed with regard to their simplicity of realization and system in organization.

Measurement System Analysis for Attributes
Širjovová, Zuzana ; Martišek, Karel (referee) ; Bednář, Josef (advisor)
Method Measurement system analysis or MSA is very exploited method for determination of the number of same and different produces today. Assesment of rightness of measurement system is often used but on the other hand it is mathematically deficiently catched up. The measurement systems analysis is more necessary, if a production system and the produce are very complex and advanced. Therefore requierement of MSA use in different types of industry is very common. MSA for attributes is the basic subject of my bachelor thesis. Complete MSA for attributes will be shown here with collecting datas and then their processings and evaluations. Software MINITAB 15 will be used for this procedure. The bachelor’s thesis was supported by project from MSTM of the Czech Republic no. 1M06047 Center for Quality and Reliability of Production.

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.
