Use of a coordiante measuring machine for surface quality evaluation
Vančurová, Martina ; Šrámek, Jan (referee) ; Harčarík, Matej (advisor)
This master’s thesis deals with the use of a coordinate measuring machine probe for surface texture evaluation. The thesis’ goals were to describe the Renishaw’s SFP2 probe, to analyze the measurement system of the probe and a common stylus instrument, to carry out a demonstrative measurement, to analyze measurement results and to give practical recommendations. The measurement system analysis of the SFP2 consists in the evaluation of minimal specification limits of selected roughness parameters, for which gauge capability can be proven. The analysis results are compared with the results of the measurement system analysis of the Surtronic 25 profilometer. The differences in the measuring processes of mentioned devices are demonstrated by surface texture inspection of torque converter body. For the measurement result analysis, uncertainties in the selected surface texture parameters are calculated in two ways. Finally, recommendations for the producer of the probe and for its users are worked out. The results of this thesis may contribute to a wider use of a coordinate measuring machines for surface quality evaluation.

The introduction of metrological procedures for determining the eligibility of gauges in tribology
Rozlílková, Lada ; Harčarík, Matej (referee) ; Šrámek, Jan (advisor)
This bachelor thesis deals with metrological procedures in determining the capability of measuring instruments in production in a company operating in the field of precision engineering. The main goal of each business is its competitiveness in the industry and the satisfaction of customer. Therefore in companies is a great deal of emphasis on modernizing and optimizing the production process, logistics, and reducing the enviromental impact. The customer's demands are constantly increasing and that is why the accuracy of the product is emphasized. So it is not only necessary to produce the product correctly and accurately, but also to check its quality, whether it fits within the given tolerances and meets the customer's requirements.

The proposal for the optimisation of control activities for a selected process
Kocmánek, Ladislav ; Jankových, Róbert (referee) ; Maradová, Karla (advisor)
The diploma thesis deals with the optimalization of control activities in the selected powder coating process. In today´s companies face increasing customer demands that demand high quality and speed of production. At Hitachi Energy is the powder coating process one of the most important processes, after which is introduced the final inspection of all painted parts. Due to situation on the labor market, the company cannot longer recruit new employees, but it must reduce the time and costs associated with powder coating inspection. The thesis focuses on the entire process of powder coating, identifies the most common poor quality in the process and determines the root causes of this poor quality. Based on these causes, solutions were designed and implemented with the aim of optimizing the control activity and reducing the costs of the poor quality of the powder coating process.

Design of the process of input control of deliveries in the company
Ondřejová, Kateřina ; Sámelová, Vendula (referee) ; Maradová, Karla (advisor)
The thesis analyzes the current state of the process of incoming inspection in the company. It describes the current state of the process in the company and subsequent processes that are part of the whole organization. The thesis uses the PDCA methodology to define the weak points in the measurement system, which are parts of entry control. Furthermore, it will explain how tools and their applications are used to improve the measurement system the follow-up of the incoming inspection. Ultimately I would like to avoid an increase in low quality parts in the incoming inspection process. By implementing the defined methodologies, the data can be considered eligible and can be subsequently presented throughout the whole process.
