Abstract
Basic principles of rigidity estimations and their description in physical processes of elastic deformation as an
important element to be considered in design of metal-cutting machines are discussed in terms of requirements to machine tools accuracy and precision. Besides, influence on the machine tool thermal factors which also lead to temperature errors and cause the accuracy changes of the machine tool are considered.
