Design of turning machine C axe
Jeník, Jan ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The subject of this thesis is the construction of turning machine C axis. The first part of this work includes a search of possible methods of construction drive C axis. The second part includes a choice of drive parameters, conceptual proposals for possible solutions and selecting the most appropriate variant. Also included is a 3D model of the lathe spindle with the C axis, modeled in SolidWorks 2007 and assembly drawing of spindle with C axis.

Design of C axe for large turning machine
Kulčar, Vojtěch ; Tůma, Jiří (referee) ; Blecha, Petr (advisor)
The subject of this thesis is construction of C axis of large turning machine. It contains description of C axis and methodology o its usage. Moreover it contains search of possible technical solutions of drive, breaking and measuring C axis. This thesis is describing chosen technical solution of drive and construction of c axis in design part. Also included is calculation and drawing of assembly of drive and model of C axis modeled in program Autodesk Inventor 2009.

Dynamic Behaviours of the C Axis Drive for Multifunction Cutting Center
Křepela, Jan ; Marek, Jiří (referee) ; Souček, Pavel (referee) ; Brychta, Zdeněk (referee) ; Singule, Vladislav (advisor)
his Disertation thesis involves the creating of the simulation model of the C axis drive over mentioned machine and them verification on the prototype of this machine. C axis is controlled with position feedback. Simulation model was created before the realisation of the machine prototype for the preliminary identification of the dynamic behaviours in the working cycles and them opportunity of the realisation this conception. C axis is constructed with worm gear and is controlled with help of Master-Slave drive. This torque drive eliminates the production backlash in the worm gear. The multifunction turning center, where is used this C axis, is determinate for heavy duty roughing cutting of the forged peaces, where is problem with dynamic stability of the cutting process. Simulation model includes the problems with multi-body mass system, friction on the worm gear, self locking, damping on the worm gear and the optimization of the parametrs for many regulators. Simulation model was verified on the prototype of the machine. Achieved results bring the new knowledge, which are used for simulation complicated machine nodes and this knowledge is used for research and developing of the similar mechatronics system.
