Proactive machine maintenance system
Semotam, Petr ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
This bachelor thesis concerns issues of proactive maintenance, which is focused on machine tools. The most common failures and the most widespread methods of diagnostics of machine tools are described in the thesis. There are also described the procedure of Failure mode, effects and criticality analysis FMEA/FMECA, its possible development in the future with demonstrative presentation of application this analysis on CNC automatic lathe. Subsequently, in the practical part there has been chosen, described and appraised diagnostic of vibrations. Prior to the end the process in field of solving of establishment systems of maintenance has been recommended for SMC Industrial Automation CZ LLC Vyškov.

Using the TPM in machine maintenance
Dočekalová, Petra ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
Bachelor´s thesis deals with the using of TPM (Total Productive Maintenance) in machine maintenance. The theoretical part describes the maintenance, its development and the methods used with the TPM. The practical part describes actual level of the TPM for machine maintenance in Bosch Diesel s.r.o. The aim of the bachelor´s thesis is analysis the using of TPM in machine maintenance, furthermore, to propose an extension of the existing TPM standard to effective training course in all positions. Also design a control mechanism for checking knowledge at each position. The results are analysed and evaluated in bachelor´s thesis.

Calibration of roughness standards
Šrůt, Petr ; Hammer, Miloš (referee) ; Jankových, Róbert (advisor)
This master´s thesis deals with the measurement of surface roughness on a roundness instrument Talyrond TR595S. The aim was to expand possibilities of measuring on this roundness instrument. The main benefit of this thesis is creation of the proposal for the roughness measurement components in a horizontal and vertical plane. Thesis also includes the procedure for measuring of the roughness of the circular components including calculation of measurement uncertainty.

Maintenance and diagnostics of machine tools focusing on vibrodiagnostics, electrodiagnostics and tribodiagnostics
Houška, Jan ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
Master‘s thesis deals with maintenance and related technical diagnostics of machine tools. Diagnostics methods on which is the thesis focused are vibrodiagnostics, tribodiagnostics and electrodiagnostics. Work includes design of diagnostic system and measurement of vibration and electrical parameters of the machining center. Based on given results from data evaluation, further steps in predictive maintenance and usage of technical diagnostics for machine tools are recommended. Within tribotechnical diagnostics, the thesis is based on evaluation of long-term monitoring of process liquid status, which was used in several machining machines. A procedure for the measurement of selected parameters is proposed and periodical liquid status checks are established.

Measurement of process variable – pressure
Kouba, Martin ; Hammer, Miloš (referee) ; Konečný, Antonín (advisor)
The measurement of the process quantity of pressure is an important element and condition of the functionality of many industrial applications, especially in the environment of commodity production, transport, pharmacy, food industry and many others. In practise, there are many pressure measurement methods that are applied in different environments and conditions. The choice of measuring equipment depends on many factors, such as the measurement range, environment, sensitivity, response speed, or environmental resistance. The correct procedure in their calibration and determination of measurement uncertainties increase the credibility of the measurement results. The means of data transfer in a modern concept make it possible to better secure and speed up the transfer of information in the measurement chain. All of the above-mentioned facts, in sequence and in relation to each other, fundamentally affect the resulting reliability and effectiveness of the measurement of the process quantity. The study of the measurement of the process quantity of pressure from a comprehensive point of view will allow us to analyse the individual elements of the measuring chain and their interconnection. The content of the thesis provides a basic orientation to the issue of pressure measurement and captures the main trends in individual areas.

Methods of technical diagnostics - vibrodiagnostics
Soldán, Josef ; Hammer, Miloš (referee) ; Hájková, Alena (advisor)
The bachelor's thesis deals with technical diagnostics, especially vibrodiagnostics. The work first describes technical diagnostics in general, namely its means and methods, including vibrodiagnostics. The mentioned method is the focus of the presented bachelor's thesis, therefore its description forms the majority of the theoretical part. As part of this work, the vibrations of the electric motor were measured, which were subsequently evaluated according to the standard.

Vibration analysis using modern online systems
Marek, Vojtěch ; Poliščuk, Radek (referee) ; Hammer, Miloš (advisor)
The diploma thesis solves the issue of vibration analysis using on-line systems. A model of a rotating machine was programmed for implementation, on which the data was subsequently measured. The solution was the analysis of experimental problems for the unbalance of the machine and the determination of the exact defect on the bearing. Different diagnostic methods and environments of the CMS X-Tools analysis application were used to obtain the results. The main result is a functional monitoring system that permanently monitors the condition of the machine and, if necessary, the operator is able to determine the exact failure of the device after analyzing the obtained data. By introducing on-line monitoring systems, major downtime and associated financial losses can be avoided.
