Rationalization project of air-filters production
Buďa, Vojtěch ; Heinl, Zdeněk (referee) ; Rumíšek, Pavel (advisor)
This thesis deals with rationalization layout of air and fuel filters production in the company MANN-HUMMEL (CZ) s.r.o., which ensures minimization of work in process and design optimal load of production on the basis measured and analyzed times operations of production. Part of thesis is the design layouts of workplace with selection of optimal variation which provides shortening and better overview on flow of material production.

Finishing methods of machining and their position in modern production
Buďa, Vojtěch ; Novák, Zdeněk (referee) ; Bumbálek, Bohumil (advisor)
Finishing operations represent important part of manufacturing technologies. They have expressive influence on functional product properties. Finishing operations are classified as operations with the defined tool geometry and as operations with non defined tool geometry. In earlier time, the finishing operations were realised mostly by the tool with non defined geometry. At this time, in which appear perfect tool materials take the value between finishing operations the operations using the tools with defined geometry like turning, milling. Still the finishing operations by the tool with non defined geometry are not forgotten and it takes a proper car of them. The progress direction of these technological operations is in the choice of grinding materials, in the choice of grinding wheels and also in proper finishing process first of all when finishing the brittle materials. In the report there is performed the analysis and evaluation of finishing methods and the main attention is focused on advanced grinding methods e.i. of ductile grinding. This access facilitates to achieve the surfaces with very high accuracy or to enables to omit some of final arrangement of the surface. Since there are solved the questions of cutting tools conditions selection and machine tools. It can be assumed that this method will be applied when finishing brittle materials as ceramics, optical glasses, silicon or germanium.
