Prospects of Increasing Accuracy of Precision CNC Multicoordinate Machines by Digital Correction Methods Prospects of digital correction methods for improving precision of CNC machines are considered. They estimate prospects of 6D calibration systems integration into the carrier system of precision numerically controlled multi-coordinate machines allowing real-time comprehensive correction of primary deviations, which appear as a result of moving the machine“s moving parts including their “occasional” component.

Microstructural Peculiarities of Roller Rolling of Inner Surface of Aluminium Bronze Ship Reinforcement Elements The questions of changing microhardness and microstructure during roller rolling of inner cylindrical surfaces of elements of ship fittings made of BrAJHMc grade bronze 9-4-4-1 are discussed. Multifractal parametrization of images of microstructures formed during rolling has been performed. It is shown that the hardened surface area is multilayered.

Effect of Multi-Pulse Current and Thermal Heating Modes on Mechanical Tensile Behaviour of Grade 4 Titanium Influence of pulse duration and multipulse current density as well as of heat heating modes on strain behavior and mechanical properties during tensile straining of commercial pure titanium Grade 4 is shown. The contributions of thermal and electroplastic effects to flow stresses reduction at the same temperature are compared. It is noted that the observed effects are realized without structural changes at chosen modes of action.
