Precision of cutting machines in its historical development. Part 1 An article presents system approach to various methods of evaluation and control of the accuracy and quality of metal cutting machines. It gives a historical retrospective of the evolution of the «accuracy» concept with reference to metal¬cutting machines. The article presents the trends and prospects of the development of the accuracy of machine tools when the technological structures are changed.
Combinatorial design of alloys using laser additive technologies The article observes the presentation of the newest methodology for rapid prototyping of alloys based on a combination of laser additive production technologies and combinatorial material science design. As an example, two types of compositions are chosen: intermetallic alloys of Ni¬Al, NiCr¬Al, Ti¬Al or NiTi¬Al systems and metal matrix composites based on titanium matrix with hardening inclusions such as Al2O3, TiB2 or TiC.
Robotic technologies in medicine and bioprinting The article considers existing examples of the use of robotic and mechatronic technologies in medicine. It reviews the bioprinting technology as the most modern and promising direction
of regenerative medicine. The article considers the projects on robotics in the field of stomatology and maxillofacial surgery.
