Standardized procedure of the machine tool adjustment for change of the machined part type
Nedoma, Tomáš ; Tuna, Jaroslav (referee) ; Lošák, Petr (advisor)
The bachelor thesis at hand is dealing with standardized procedure of machine adjustment in process of machined rail type change in Bosch Diesel s.r.o. Jihlava. In the thesis, procedures of external adjustment of preparations that clamp workpieces into machining centers and overall procedure of machine adjustment are described. The elaborated standardized procedures are included in instruction manuals, which are used by workers of the company for machine adjustments. These “manuals” shall minimize occurrence of defective steps in the adjustment process and prevent their interchange. Mistakes based in incorrect procedure of the workers lead to prolongation of the time necessary for machine adjustment in process of change of machined type by up to hundreds of minutes per month. Bosch Diesel s.r.o. has adopted these instruction manuals and thanks to them shall save couple of tens of thousands euro per year.

Application of EDM in combination with milling
Drmela, Radim ; Mouralová, Kateřina (referee) ; Zemčík, Oskar (advisor)
The diploma thesis is notionally divided into three parts. The first literature search part deals with the electronic discharge machining. The second main part solves the problem of machining plungers (movable part of the injection mold). This part also includes a technological process including production instruction cards. There are also calculated costs of production for this diploma part. The last part compares applications of electronic discharge machining technology with applications of milling technology.

Suggestion of technology for roller body
Drmela, Radim ; Mouralová, Kateřina (referee) ; Zemčík, Oskar (advisor)
The bachelor thesis deals with the technology of manufacturing roller body in Kovo Šmerda company. The first part is focused on the analysis of technology. The second part is practical, explains the technology of manufacturing for roller body, used in mine carts. The practical part contains the technological process of manufacturing, manufacturing instruction cards. It also shows the techno-economic evaluation and CNC program.
