文摘

Properties of a machine tool significantly depend on the stiffness of its constructional system, which consists of the stiffness of all parts of the system. Special importance is attributed to the stiffness of the movable and fixed joints existing in the machine load carrying system. The paper describes a method of calculation of the static properties of guideway joints using finite element analysis. In its computational models, the presented method considers phenomena occurring in the contact layer of these joints.
