Řezání abrazivním vodním paprskem / Abrasive water jet cutting

Midrla, Zdeněk January 2013 (has links)
This master thesis is consisted of literature search and practise part with focusing on the theme of abrasive water jet cutting. Introductory chapters deal with various methods and principles water jet cutting. Following chapters deal with quality of cutting surface by abrasive water jet cutting. After these chapters is introduced machine equipment of water jet cutting technology. At the end of this theoretical part are listed advantages and comparison with other unconventional technologies. In the practical part is solved design of machinery with regard to manufacturing technology of component flange in series 630 000 pieces per year. Last chapter describes economic evaluation of production.

Technologie výroby vymezovací podložky / Manufacturing technology of the distance washer

Dvořák, Jiří January 2011 (has links)
This master’s thesis has been elaborated as a part of master’s studies of engineering technology M2I-K, major in M-STM – Engineering technology and industrial management and deals with the problem of a transition to a self-production of previously purchased distance washers. Distance washers were purchased in six different types of similar shape, each type in four different thicknesses. One of these types was chosen as a representative for this master’s thesis. We shall explore the possibilities of self-production with the emphasis on economical validation of the transition. The distance washer is a flat part, the intermediate being sheet metal. Technologies considered for manufacturing the washers correspond to the technical facilities and equipment available at the production hall of the company this project is planned for. The company possesses technology for CO2 laser cutting, cutting by CNC punching machine and cutting in the punching tool. To provide a complex overview we shall also enquire into cooperated technologies such as water jet and plasma cutting, oxy-acetyleny cutting and CNC working. All options are evaluated with regard to the production expenses and lead to a most economically plausible method of manufacturing or, if need be, give reasons for going back to purchasing the part from the current supplier.
