Dynamic simulations of linear displacement system of CNC milling machine
Gregor, Jiří ; Tůma, Jiří (referee) ; Klíč, Daniel (advisor)
This thesis deals with dynamic simulations of a linear feed system of a CNC milling machine in Adams View. Dynamic simulations enable better and faster decision making when designing new machines than prototyping. The aim of this work is to compare the torque waveforms on ball screws at working feed and at quick feed. The next task is to measure the forces acting on the load body. The values were obtained by simulation in Adams View and measurement on a CNC milling machine MCV Quick 754. The results were exported to Matlab. The resulting torque waveforms were compared, where they are relatively identical during working feed, with large differences during rapid feed.

Linear feed systems in construction of machine tools
Kolaja, Radim ; Opl, Miroslav (referee) ; Blecha, Petr (advisor)
This bachelor thesis deals with the detailed description and division of constructional componets composition of linear feed systems, which are essential part in the construction of machine tools in the manufacturing process. It describes individual subsystems, which are described in details and compared in terms of favorable and unfavorable characteristics for certain working conditions. Out of these possible ways of implementation of linear feed system is initiation one example with an overview of the basic calculations used to design project.
