Presented paper is focused on the modelling and description of the proposal of composite frame construction of the new CNC machine, which is designed for progressive machining of products made of powder materials produced by the additive Direct metal laser sintering technology. In the introduction of the article, the uniqueness of the created bed design of the machine tool based on the mixture of polymer concrete is emphasized through general knowledge. Subsequently, the paper determines the properties of the polymer concrete mixture, which forms the basic material of the machine tool bed, describes the design of the CAD solution and the complex strength analysis at the determined load of 950 N with the subsequent interpretation of the results. Within the stress analysis, the Von Mises combined voltage is in the range of 0.2 - 0.4 MPa, thus meeting the required values of the formed material. In order to ensure the complexity of the evaluation of the proposed design solution, the results achieved by modal analysis are also presented in the paper. The conclusion of the article provides an overall summary of the achieved results and describes the further direction of research. [ABSTRACT FROM AUTHOR]
