Department №20. Department of Promising Resource-Saving Technologies of Machining

Who we are

Department №20 "Perspective resource-saving technologies of machining" is structural division of V.N. Bakul Institute for Superhard Materials.

The scientific and applied interests include developing of the theory and application of resource-saving processes of cutting and cold plastic deforming (the CPD) for improving of functional and working behavior of hardware, geome-trical and mechanical properties of surface layer; shaping processes for surfaces of an intricate profile at gears, spline drives, ball joints, and also a medical implants by tools from super-hard and other advanced tool materials.

In particular, researches are directed on:

•developing of the theory and practice of perspective resource-saving proce-sses of cutting and the CPD by tools from super-hard and other advanced tool materials;

•developing of the scientific basic of improving of a resource of a hardware by the CPD, including:

-creating of surfaces of an intricate profile in article of type "bush" by reducing method;

-creating of a gradient structures (small-grained and/or nano-sized) in surface layer of materials including titanium and its alloys;

-engineering of surface layer of materials, including titanium and its alloys, by a combination of the CPD and thermal diffusion saturation by penetration elements;

-compacting of powder materials with necessary porosity by the localized step CPD into closed space;

•developing of the scientific basic for diamond machining of a medical implants from advanced materials (sapphire, biologically inert ceramics and metal alloys), including joint components for endoprostheses of joints in order to improve its working life;

•developing of the scientific basic of creating of the surfaces of an intricate profile at gears, spline drives and another hardware by cutting and/or deforming tools.

Research Areas

We are researching in the next R&D field:

•improving of a resource of hardware by the CPD;

•creating of surfaces of an intricate profile in article of type "bush" by reducing method;

•creating of a gradient structures in surface layer of materials including titanium and its alloys;

•engineering of surface layer of materials, including titanium and its alloys, by combination of the CPD and following thermal diffusion saturation by penetration elements;

•improving of working life for a medical implants from advanced materials including joint components of endoprostheses of joints;

•creating of the surfaces of an intricate profile at gears, spline drives and another hardware by cutting and/or deforming tools.

Main achievements

•Radial compacting method by means of the localized step CPD into closed space was created for decrease of porosity from 30‰ to 5‰ at long-length (5…10 diameters) sleeves from powder materials

•Technologies was developed for creating of spherical surfaces at medical implants of type "truncated ball":

- on sapphire and biologically inert ceramics with non-sphericity <1 µm and roughness Ra<0,02 after diam-ond machining;

- on pure titanium with non-spheri-city < 3 µm and roughness Ra<0,04 after a combination of surface strain hardening and diamond machining;

•To create gears of any profile by worm, disk-shaped or rack tools were proposed due to developing of theo-retical basic, new cinematic scheme and technological ways.

Reference projects

•STCU international (with Kharkov Institute for Single Crystals and Georgian Technical University) project #3596 "Influence of Anisotropy of Crystal Lattice On Workability and Quality of Medical Sapphire Implants" 2006-2007.

•STCU international (with Kharkov Institute for Single Crystals and Georgian Technical University) project #4596 "Development of methods for hardening of sapphire used in medi-cine" 2009-2010.
