Thermal Rigidity Of Machine Tools. Physical Fundamentals. Evaluation and Control. Part 2. Thermal Rigidity – Engineering Basis for Assessment and Management
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 changes in accuracy of the machine tool are considered.

Tool Coatings Based on Tialn Produced by Middle-Frequency Pulsed Magnetron Spraying
Abstract
The effect of pulse frequency during pulsed magnetron sputtering of a TiAlN coating on changes in the phase and elemental compositions of coatings, their microstructure, surface
roughness, and physical and mechanical properties is considered. The optimal value of the pulse frequency at which a coating is formed based on the highly dispersed wear-resistant h-Ti 3Al2N2 phase with a dense nanocrystalline structure, minimal surface roughness, high microhardness and elastic recovery is established.
