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.

Reliability assessment of a hydraulic switchboard production proces
Machová, Lenka ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The Diploma thesis is focused on possibilities of an assessment of a hydraulic switchboard and its manufacturing process. Furthermore, it analyses methods individually which are suitable for quality assurance and production reliability, which are described in details. The follow-up work focuses more on the Statistical Process Control (SPC) method which is applicable in the early warning system and the Failure mode, effects, and criticality analysis (FMECA) method, applicable in the planning system. These two methods are further applied to the newly introduced process of machining the hydraulic switchboard as an effective tool not only for assessing the reliability of production, but also for its subsequent securing and maintaining in a relevant condition.

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.

Evaluation of statistical quality control (SPC) in solving the stability of processes in die castings
Hejduk, Oldřich ; Morávková, Jitka (referee) ; Čech, Jaroslav (advisor)
The aim of the theoretical part of this thesis is to describe the system of the aluminium casting alloys, with focus on the aluminium castings used for die casting. In this part of the thesis the different methods of the quality management are described. The practical application of these methods is described in the experimental part of this thesis, in which we focus on the evaluation of the statistical quality management and the process stability of the die casting parts of the selector mechanism cover. This part of the thesis also contains suggestion for the QFD method for this cast.

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.

Statistical methods in quality management system.
Vyškovský, Jaroslav ; Toul, Jiří (referee) ; Fiala, Alois (advisor)
Statistical methods in quality management system are strong tools, which helps us to make right resolutions in area of quality management, or in other possible areas, such as process control, or in assessing of specific parameters in company. In these respects we are using various norms, manuals and publications such as ČSN EN ISO 9001, ČSN EN ISO 9004 a ČSN ISO/TR 10017. In the beginning part of work we are gradually dealing with basic phraseology from area of statistical methods, next we continues with management and with process, SPC, description of basic statistical methods and in the end by data. Goal of this work is literature exploration of facts and own conclusion connected with predict of progress in these area.

Implementing SPC in the Production Process
Dostál, Petr ; Macháček, Martin (referee) ; Bartes, František (advisor)
The thesis deals with implementing of statistical process control (SPC) on CNC cut center into the mechanic production. One part of the project is engaged in theoretical information gathering, process monitoring and data collection. Second part deals with stabilization, regulation and improvement of the process using right statistical instruments. As a result is implementing measuring station from where will be the process data transferred to a server and evaluated. On the basis of that is possible to implement a correction in the right time if the process isn´t stabilized. The main objectives of the thesiss are cost reduction, scrap reduction and modernization of the process.
