Sinumerik 840D control system for turning of the shaft for JAWA 23
Motl, Martin ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This Master’s thesis deals with the proposal manufacturing technology of a shaft with gears on a CNC machine tool. The first part of the thesis is focused on the concise description selected shaft and its use. In the next part of the thesis are state selected materials, which are suitable used for shafts and gears. After that is create drawing component, suggest technological procedure, tool list and machine list which are suitable used for manufacturing selected shaft. In the final part of the thesis is create a CNC program for manufacturing the shaft on the turning and milling machine. Program is created in software SinuTrain 4.7 for control system Sinumerik 840D. The CNC program is verified by graphics simulation to determine a correct function

Repair of surface sliding
Teplý, Miroslav ; Vyplašil, Evžen (referee) ; Kubíček, Jaroslav (advisor)
The selection of suitable materials for the renovation of sliding shafts requires a comparison of several criteria. The main criteria were selected size shear strength under tensile stress lap bonded assemblies, resistance to adhesive wear and economic criteria. From the results of all tests is selected the most suitable friction material to repair worn out places of shaft. The technological process of sealing the shaft was drawn up on the basis of the literature, recommendations supplier of sliding materials and their own experience.
