Abstract

The thesis deals with the design of a CNC milling machine for machining plastics and aluminium alloys. In the introduction of the thesis, the theory of machining is described, supplemented by a description of the function of individual elements of the machine necessary to understand its oper-ation. Then a search of existing equipment is carried out followed by the selection of the design procedure. For the dimensioning of the machine frame, cutting forces are determined according to specific materials on the basis of which the inspection of the functional parts is carried out. At the end of the work, the designed frame is subjected to FEM analysis in order to check its defor-mations. The output of this work is a drawing documentation of selected parts and assemblies.
