Machining of thin-walled components on a CNC lathe
 Veselský, Radim ; Kolomý, Štěpán (referee) ; Slaný, Martin (advisor)
This work was focused on the design and production of a clamping device for clamping thin-walled circular workpieces on a CNC machine. Cutting forces were measured using a dynamometer. From these forces the highest power was derived. The minimum clamping force for clamping the workpiece was calculated. Using simulation, the most suitable angle of spacing of the clamping surfaces was determined. Based on this finding, the jaws were designed and manufactured. 5 samples were processed. Three samples were machined in the original jaws, two samples were machined in newly manufactured jaws. Each jaw was clamped with two specified clamping pressures. The machined samples were scanned with an optical scanner and measured in a measuring program. A clamping simulation took place with the determined pressures of both jaws in the simulation program. Conclusions were drawn from the calculations and the verification experiment.
