Sinumerik 840D sl. tools for programming of CNC machines
Mešina, Matej ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
The thesis deals with the design and production technology of the front hub for a mountain bike. The research focuses primarily on the various control systems of CNC machining apparatuses. The second chapter is devoted to the elemental differentiation of hubs, the concept of personal design of the hub, and the characteristics of the materials for its production and its verification using the FEM analysis. The third chapter deals with the design of a workpiece, instruments and the manufacturing process itself. The design of an NC program constructed in the SinuTrain 4.8. software is dealt with in the fourth chapter. The last part is devoted to the technical and economic evaluation of the proposed solution.

Machining of the gear-box casting on a CNC machine
Hložek, Milan ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The master’s thesis focuses on the machining of a chosen gearbox on a CNC machine. The theoretical part deals with gearboxes in general and the aluminium alloy from which a selected gearbox is manufactured. In the practical part, the machining of the gearbox is proposed according to the corresponding drawing. Gradually suitable machines are selected, then depending on their limits, clamping devices are designed, next a set of tools is selected and an NC program is generated. The technological process of production is proposed and the basic production costs are calculated.
