On the effect of tempering and storage conditions of rubber parts on final joint cohesion
Jílková, Ingrid ; Kalivoda, Milan (referee) ; Píška, Miroslav (advisor)
This bachelor’s thesis deals with an analysis of waxing phases occurrence on the surface of the technical rubber which is used in the automotive industry. The theoretical part of this thesis deals with a composition and manufacturing of the rubber. It is focused on the composition of rubber compounds and waxes. It explains technical properties, reasons (advantages) of the ingredients in the rubber components. Next, it also clarifies the substance of the wax and its use in relation to rubbers. The theoretical part also clarifies the storage of rubber parts and why is it desirable to identify the wax which is separated on free surfaces of rubber. The practical part deals with a suggestion of the identification methods for the waxes on the surface of rubber. It also presents the comparison of the possibilities of the methods used for the identification of wax and its evaluation.

Problems of the mirror shutter in the LED module of the headlight
Ettler, Jan ; Hlaváček, Martin (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with methods of attaching the mirror shutter in LED modules in headlamps. The aim is to compare three methods of attachment which are used in one of the platform variants. The following are the methods of attachment, followed by the description of the light sources and functions of the LED modules; they are: riveting, hot stamping and fixation with clips. Risk associated with the assembly of mirror shutter into the light source are analysed via FMEA analysis, including also measures and actions for risk reduction – implementation of lighting of produced light sources in a special jig in the light laboratory. Vibrations tests were carried out to find out the influence of vibration on the mirror shutter in LED modules in the traffic. The tests revealed that even if the clip is incorrectly fixed (not attached to the end position) it does not affect the functionality of the module.

Grinding of Bearing Rings
Růžička, Daniel ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The main objective of this work is to evaluate the surface quality, machined on three different grinders (all three from different age), and to compare those grinders. Comparison is done by the achieved degree of precision of measured geometric tolerances in inner orbits of the outer bearing rings. As the best grinder is expressly marked the newest (type CNC) however, the second in a row (the second youngest) is very close to its quality and finally it is noted that the purchase and operation of this grinder is more convenient.

Hořava, Lukáš ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The object of the bachelor thesis is the method of chip and non-chip production of threads determined for mainly metal products. The first part is focused on the products which have been producing by company EDP, s.r.o. Further, the individual thread types, the most common methods of their production and the methods used in the company are mentioned. In the following experimental part, the production of samples with shaped threads and machined threads are described. The attention is also dedicated to the adventiges, and disadventiges of the methods used by the company, as well as the economic appreciation. The conclusion is made of proposal of the thermal drilling and its evaluation.
