Gears created by 3D printing for consumer use
Chládek, Vilém ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with gears and subsequently with 3D print. 3D print is nowadays a rapidly evolving technology which can solve complex assemblies. This text contains gears analysis and their parameters. The next section describes 3D printing technologies and the materials used. The main point of the solution is elaboration of the 3D model of a hand-powered drill and its subsequent 3D print. With this is discussed, the issue of fitting, model assembly and post-processing. A successfully printed and functional drill can be then used for educational purposes or as a suitable pattern for the kit.

Application of CAD/CAM technology for design and manufacture of a prototype of pitman front wheel
Bardoň, Václav ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
This master's thesis deals with design and manufacture of a prototype of pitman front right wheel of student's formula Dragon 4 of a team TU Brno Racing with use of advanced CAD/CAM technology. Opening part of the thesis deals with the theoretical analysis of milling technology. Furthermore, there is an analysis of aluminum alloys, which aims to integrate the material being machined CERTAL. In the practical part of the work the construction of pitman is done using CAD software SolidWorks 2012 and proposal of milling strategies is done using software PowerMILL CAM 10. The following is the realization of manufacture in CNC machining center MCV 754 QUICK at Bosch Diesel Ltd, in Jihlava. Techno-economic evaluation of the manufacture is done in conclusion.
