Optical measuring instrument SOL 311
Kellerová, Michaela ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The main benefit of this bachelor thesis is the assessment of conformity with the specification in accordance with the ISO GPS system. In the theoretical part, coordinate measuring machines were discussed with emphasis on multisensor measuring machines. The practical part is focused on the evaluation of measured values of components on the CMM SOL 311 according to the standard ČSN EN ISO 14253-1: 2018.
3D Scanning System Proposal for Plastic Parts
Palátová, Zuzana ; Jankových, Róbert (referee) ; Sámelová, Vendula (advisor)
The diploma thesis is focused on monitoring and description of the current state of plastic injection molding production and analysis of methods for measuring these parts. Measurement methods are described and at the same time the measurement issues associated with individual types of meters for specific plastic parts are presented. Based on the analysis of measuring systems, a design of the measuring device in the form of a 3D optical scan is subsequently created, which is optimal for the selected plastic components. When choosing a 3D optical scanner, a demand is created that takes into account the necessary technical parameters required by the corporate environment. A selected proposal is presented at the end of my work.
Quality assurance of horizontal road marking equipment
Janáč, Ondřej ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
The diploma thesis deals with the requirements for the quality of equipment for horizontal road marking, which is manufactured and assembled by the manufacturer. Within the philosophy of continuous improvement, this work describes a project leading to a reduction of the number of parts, that do not fulfill their function after assembly. The main benefit of the work is a proposal to modify the production documentation and change of the measuring equipment used in its inspection. All taken measures have reduced the number of defective parts. It also provides an overview and general procedure of the selection, analysis, implementation of another measures and the use of other opportunities to improve the quality management system of horizontal road markings in the company in accordance with ISO 9001.
Quality assurance of mechanical shaft seal assemblies
Příkaský, Jakub ; Maradová, Karla (referee) ; Jankových, Róbert (advisor)
The thesis deals with the issue of a selected sealing shaft assembly. On this assembly, a nonconformity analysis was performed and corrective measures were proposed, applied and verified in a subsequent PDCA cycle. Furthermore, realistic improvements have been proposed that can have a significant positive impact on the overall quality of this shaft seal assembly in the future. The main contribution of this thesis is to reduce the number of non-conformances and on top of that to deepen the management of modern quality methods in the collaborating organization.
Application of CAD/CAM software for machining
Havran, Lukáš ; Jankových, Róbert (referee) ; Polzer, Aleš (advisor)
The aim of this bachelor thesis is the application of CAD / CAM system in machining. It contains a brief search of the possibilities of programming in CAD / CAM systems. Software that were used in this work were Creo Parametric from PTC and PowerMILL from Autodesk. The practical part of this work is focused on the production of a copy of a physically existing component using selected systems. In this part, attention is paid to the creation of a 3D model together with production of documentation using the Creo program and the creation of the machining program in PowerMILL for the implementation of production at CNC machine. The proposed procedure is verified by graphical simulation. Part of the practical part is also the selection of suitable machinery and tools for the actual production. The conclusion of the work is devoted to the control of the manufactured component.
Determination of measurement uncertainty of a coordinate measuring machine in nanometrology
Potanko, Andrej ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
The diploma thesis deals with the determination of measurement uncertainty on coordinate measuring machines in the field of nanometrology. These are SIOS NMM 1 and Zeiss UPMC 850 Carat machines, which are used at the CMI workplace in Brno. In the theoretical part, the work is devoted to basic terminology in the field of measurement and general characteristics of coordinate measuring machines. The theoretical part concludes with a description of the devices used for measurement. In the practical part, experimental measurements are performed on both devices with subsequent identification and quantification of individual components of uncertainties affecting the measurement. The last part of the thesis is devoted to the overall evaluation of measurements on Zeiss and SIOS devices and their metrological comparison.
Quality assurance of ultrasonic instruments
Macková, Ivana ; Jankových, Róbert (referee) ; Maradová, Karla (advisor)
The master’s thesis deals with quality assurance of ultrasonic instruments. The thesis presents the ultrasonic technologies, the types of ultrasonic tools used nowadays and the requirements for their quality. The thesis addresses the issue of time-consuming quality control of ultrasonic instruments. The solution of the given problem consists in the use of statistical process control and application of acceptance sampling. According to the sampling plan, the acceptance number and the sample size to be checked during the output inspection is determined. By reducing the number of pieces to be inspected, time and financial savings are achieved.
Machine tool spindle quality assurance
Marek, Tomáš ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
The master thesis deals with the problem of quality assurance of headstock in a cooperating company, which is one of the leading manufacturers of grinding machine tools. The aim was to analyse the current situation and to suggest possibilities for improving the quality of the spindle. The main contribution is the introduction of control charts for individual values and a capability index to monitor the stability of selected production processes. The thesis concludes by suggesting a number of further options for improving the quality management system in the collaborating company, which should be considered by the company.
SW for balancing rotary machines
Dúcky, Martin ; Jankových, Róbert (referee) ; Zuth, Daniel (advisor)
This thesis deals with balancing of rotary machines in one plane. It is divided into a theoretical part and a practical part. The theoretical part is deals with the basics of vibrostatics and operational balancing, with emphasis on the evaluation of machine vibration. The practical part deals with SW solution in Matlab environment. It explains the functionality of individual parts, their arrangement, connection and mutual continuity, and layout of the program. The programmed solution is tested on a series of measurements in which the balancing itself is evalated and compared with the classical method used in balancing rotary machines in one plane.
