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.

Proposal of conformity assessment and inspection procedure of a cyllinder flange
Ondruška, Jan ; Jankových, Róbert (referee) ; Harčarík, Matej (advisor)
This bachelor thesis contains the control plan creation procedure for conformity assessment of a cylinder flange. The thesis includes a selection from standards related to the above-mentioned problems and the drawing documentation of the part. The cylinder flange is analysed in terms of function and unambiguous specification of geometry on the drawing of the part with regard to further part inspection. Any deficiencies in clarity are dealt with in more detail and solutions to these problems are proposed. Control plans for inspection of the part directly in the manufacturing process and for inspection of the part during sampling were created using CAQ software and are attached to the work. The results of the work have been used to improve the process of manufacturing of the part.
