Implementing of SPC into production process
Letáček, Jiří ; Koška, Petr (referee) ; Fiala, Alois (advisor)
This graduation thesis is concerned with implementing the SPC (Statistical process control) to the process plan. The aim of this thesis is an analysis of present status of manufacture laths bending and a selection of useful methods, which is possible to apply in a company processes. The main reason for SPC implementation is continual improvement of quality in manufacturing concern. The theoretical part of thesis consist of bending description, control of process quality, quality control instruments and errors in measurement. In practical part is described an actual status of manufacture and a solution of query.

Study of implementation of SPC statistical method for control of technological operations
Ondruška, Jan ; Zeman, Karel (referee) ; Jurová, Marie (advisor)
The master’s thesis contains a procedure of implementation of statistical process control for a machining process in a chosen company. The method is based upon knowledge of this topic which are mentioned in the first part of the thesis. The output is a comparison of general process performance before and after implementation of the above-mentioned statistical method and evaluation of the influence of this new method at the process. The comparison is done using hypothesis testing of specific statistical variables and analysis of process performance and capability of both data sets. The acquired knowledge and experience will be used for implementation of statistical process control for other processes in the company’s production portfolio.

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.

Data processing from measurement on machine tools
Pokorný, Zdeněk ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
The Master’s thesis deals with the precision of machine tools, especially with the three-axis vertical milling machine. It is structurally divided into a theoretical and practical part. While the theoretical part focuses on problems of geometric errors and measuring devices, the practical one is devoted to the machine tool being tested. In this case, the data processing and the proposed statistical analysis are essential, and at the end of the thesis another possible way of developing the data processing is outlined.

Use of Contol Charts in Quality Control
Ječmínková, Michaela ; Klimčík, Pavel (referee) ; Kropáč, Jiří (advisor)
This diploma thesis deals with use of Shewhart Control Charts in quality control. The thesis describes the currently used process of quality control in the enterprise. Afterwards practical guidance for implementation of the statistical process control of the selected component and evaluation of capability is provided. An application for creating control charts and monitoring the quality of the product is included.

Determination of capability and stability of a chosen technical process
Šváchová, Mariana ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
This diploma thesis deals with the evaluation of the capability of a specific production process. The theoretical part of the work contains a description of statistical process control, types of control charts and evaluation of process capability. The practical part is focused on evaluating the capability of a specific process. The method of dataset collection is described at first, then this data are analyzed and the capability of this process is evaluated.

Scrap Analysis in Manufacturing Process
Buriánková, Alena ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
The master’s thesis is focused on the reduction of rejection rate in production of plastic bowls with the use of statistic methods. The theoretical part of this thesis describes among others Statistical Process Control, Process capability and types regulatory diagrams. The basis for the practical part is data collection over a certain period of production, from which the percentage of the rejection rate is evaluated. Experiments and corrective actions are designed to improve the process and thereby reduce scrap.
