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.

Design of CNC milling machines for modeling workshops
Kovács, Zdeněk ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
This diploma thesis deals with the design of a CNC milling machine for the puspose of modeling workshop. In the first part is carried out the search in the field of small CNC milling machines for better familiarization with this issue. The information obtained in the first part of the thesis is used for determination the parameters of the designed machine. The last part deals with the design and realization in the form of a 3D model.
