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.

Coating methods for cutting tools
Tuna, Jaroslav ; Prokop, Jaroslav (referee) ; Humár, Anton (advisor)
This diploma thesis is aimed on methods of the coating cutting material (cemented carbide, cermets, cutting ceramic, super hard materials) and evalutation individual method regarding technological posibilities of deposition of hard coatings a their mechanical, thermal and che-mical properties. The task of the work is full elaboration obtained technical knowledges and mainly evalutation a comparison of the work conditions (kind of the cutting materials, cutting conditions) that selected producers recomended for effective turning aplications of the coa-tings cutting materials.
