Design of a milling fixture for four-axis CNC trimming of composite parts
Hibš, Dominik ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This thesis deals with the design of a milling fixture for trimming of folding propellers for the company Mejzlik Propellers s.r.o. Firstly, an adequate HAAS DM-2 machine and UniCut Dron milling tool were selected. The cutting force was then quantified at 9.2 N. Once the cutting force was established, the clamping surface could be designed and the clamping force set at 317.3 N. After considering several fixture options, the final design was selected. The selected design was used to program the CNC machine in Fusion 360. A technical and economic evaluation followed, when the total price of the product was 41,671 CZK and the cost of machine cutting one propeller was 32.60 CZK, while the cost of manual trimming was 29.10 CZK

Machining of a guide wheel from turbocharger
Hibš, Dominik ; Varhaník, Matúš (referee) ; Kalivoda, Milan (advisor)
The topic of the bachelor’s thesis is to develop a design for the production of a distribution wheel for a turbocharger. The design includes a description of the part, the choice of material, machines, tools, and the development of the production process. The outcome of this thesis is the creation of a NC program in the HEIDENHAIN system.
