Technological and economic analysis of the production for the automotive industry
Sedláková, Eva ; Petrenec, Martin (referee) ; Píška, Miroslav (advisor)
The thesis deals with an analysis of an existing technology of thread forming under various technological parameters used in car industry. Furthermore, it characterizes metric threads, their production and quality control, forming taps, process fluids and other process parameters. In the experimental part the experimental tests with a conventional and CNC drilling machines were carried out. The influence of various process fluids on surface and thread quality have been assessed statistically. The technical-economic evaluation of the process fluids and their effect on the technology has been made. The work supports a beneficial role of soap and polymers as convenient tribological means at thread forming.

Production of connector
Kočka, Jiří ; Rumíšek, Pavel (referee) ; Žák, Ladislav (advisor)
The diploma thesis deal with the proposal of connector manufacturing from bronze sheet CuSn6, thickness 1.5mm in production volume of 1.600.000 parts per year. From considered manufacturing variants there was chosen shearing and forming technology of thread in the progressive stamping die. For part production was selected pressing machine Bruderer 1250 with nominal pressing force 1250 kN from company E. Bruderer Maschinenfabrik AG. In the economical evaluation there were determined expenses 21.6 Kč per one piece including demanded profit. The turning point was calculated at production of 165.522 parts.

Formed and Machined Threads on Products from Sheet Metal in Company European Data Project s.r.o.
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.

On the modern technologies of thread production
Mišák, Ondřej ; Dvořáková, Jana (referee) ; Píška, Miroslav (advisor)
This bachelor's thesis deals with the study of threads, specifically the introduction to the basic geometry of threads, their production and modern trends by which threads can be made. The experimental part is devoted to the production of threads using cutting and forming taps, comparison of force and moment loads and damage caused during the production of threads when changing the cutting speed. In the end, the achieved results of experimental tests and their evaluation are summarized.
