Production technology of horizontal cable tray for low-voltage switchgear ABB
Attasek, Ondřej ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
In bechelor thesis is the main task of manufacturing the component that is made of galvanized steel sheet of DX51D+Z/+Z material with thickness of 1,5 mm. The component is produced using technology of cutting and multiple bending. The main aim is to suggest technological process of cable tray for installation of low voltage switchgear for the ABB Ltd. company. Yearly production expectation is 2 650 units. Part of the work is also required technological calculations for notching plan, cutting force and force for bending. In thesis is also elaborated technical-economic evaluation with the drawing documentation.

Cemented carbides and theirs effective use
Crhan, Luboš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
Bachelor's thesis is elaborated in an bachelor's study program B2341 - Engineering, branch of Engineering Technology at the Faculty of Mechanical Engineering in Brno. Work is focused primarily on issues of cemented carbides cutting tools and their effective use during machining. The first chapter describes basic informations on distribution, labelling, raw materials, manufacture, properties of cemented carbides, etc., from literary sources. Other chapters are devoted to evalution and comparsion of cutting conditions for different types of tool materials from different manufactures.
