The article presents a design procedure of machine tool (MT) columns having sufficient rigidity with minimum weight. Methodology uses the method of gradients balance (BG-method), proposed by Professor G.N. Vasiliev at Bauman Moscow State Technical University. The specialized software for its implementation was developed, on the base of which the deformation processes of columns of various configuration and size under the action of cutting forces were simulated. Experimental studies of rigidity of MT column models took place and confirmed the possibility of practical use of the chosen method of model ing. The finite element model ing of the deformation processes of MT columns by a computer program ANSYS was carried out that also proves the feasibility of its using on the early stages of MT design, while choosing the cross-sectional parameters of a new machine-tool column. The results confirm the possibility of a methodological approach to optimize the design parameters of MT columns by criterion of sufficient rigidity with minimum weight.
