The paper presents theoretical and experimental modal analysis of the machine tool lathe body made of cast iron. Modal analysis is commonly used in practice as a technique for determining the dynamic properties of objects. The aim of the work was to compare the theoretically obtained results with experimental research. The modal analyses both theoretical and experimental were conducted in frequency domain in range from 0 to 1600 Hz. Results from theoretical modal analysis were highly convergent with experimental studies. This verification of theoretical model with experimental results gave justified basis to conduct the research based on verified model. The model could be subsequently applied to perform simulations of the analyzed body behavior in the conditions which were not examined experimentally. On this basis, the conclusions about dynamic behavior of the analyzed object were formulated
