Hobby milling machine design
 Valášek, Ondřej ; Zemčík, Oskar (referee) ; Dvořák, Jaromír (advisor)
At the introductory part, this thesis deals with description of individual parts of construction and control of CNC machine. Individual parts are described by vievpoint of principle of function, attributes and possibility of implementation on hobby machine. Furthermore is performed brief analysis of commercially manufactured CNC milling machines, which can be purchased on domestic and foreing markets for a purpose of milling wood and eventally aluminuum alloys. Main purpose of thesis is custom desing of CNC milling machine for non-commercial use. Three draft proposals are created first. Then one of them is developen into complete proposal. This design is then subjected to numerical simulation to pre-determine the machine's stiffness and ability to milling aluminium. The result of this simulation confirms the possible use of the machine for milling aluminium alloys. According to the simulation, the maximum deformation for possible machining of aluminium under predetermined conditions is 0.18 mm. In the last part of the work a price calculation was made, determining the approximate cost of the machine production at 75 000 CZK. The work includes a complete drawing documentation of the mechanical parts of the machine.
