STC G - 2016 Annual Report

The year 2016 was successful for the Scientific Technical Committee STC “G”. Fifty-five people attended the STC G winter meeting in Paris in February, and fifty-eight people attended Part II of the STC G meeting held at the 66th General Assembly in Guimaraes, Portugal, in August.

In the STC G winter meeting, Mr. Hashimoto updated the progress of the 2016 keynote paper “Abrasive Fine-Finishing Technologies,” and the contents were confirmed and approved. Mr. Wegener updated the progress of the 2017 keynote paper “Recent Developments in Grinding Machines,” and the contents were approved. Mr. Shih updated the progress of the 2018 keynote paper “Abrasive Machining of Non-Metallic Materials,” and the contents were provisionally approved. Mr. Aurich updated the progress of the 2019 keynote paper “Abrasive Processes for Micro Parts and Structures,” and the contents were provisionally approved. It was also approved that the above-mentioned keynote papers (2016, 2017, 2018, and 2019) be forwarded to the Liaison Committee as the STC G future keynote papers.
Eight topics were presented in the technical contribution session. The topics included microorganism-suspensions as alternative metalworking fluids, material modifications in grinding, metal-bonded grinding wheel properties altered by sintering conditions, multi-physics analysis of surface integrity in grinding, energy demands in grinding, modeling of tumble/vibratory finishing equipment using physics engines, hybrid abrasive blasting using cryogenic ice, and role of surface roughness in biopsy performance. In the laboratory presentation session, an overview of the Center for Manufacturing Innovation at the University of Florida, USA, was introduced.
The STC G contributions to Part I of the 66th General Assembly in Guimaraes included a keynote paper, “Abrasive Fine-Finishing Technologies” presented by Mr. Hashimoto, and nine regular papers. The keynote paper provided a comprehensive overview of abrasive fine-finishing technology along with the process classification (based on the material removal mechanisms), specific energies required for each process, surface characterization, and recent trends. The keynote paper was well received. The regular papers presented covered a broad range of topics, including metalworking fluid additives for grinding, grinding fluid flow in cylindrical plunge grinding, modeling of thermal effects in internal traverse grinding of hardened bearing steels, modeling of material removal in vibratory finishing, cutting-edge preparation with elastic-bonded superabrasive grinding wheels, bronze-bonded grinding wheels, a grinding process for profiled texturing, grinding with controlled kinematics and chip removal, and grinding characteristics in rotational atherectomy of calcified plaque.
Highlights of the STC G meeting in Part II of the 66th General Assembly in Guimaraes included eight technical contributions, one laboratory presentation, the 2016 keynote paper, and three future keynote papers. The technical contribution topics included energy influence on material modifications in grinding, chip formation in grinding, texturing cBN grinding wheels using rotary discs, surface grinding with electroplated cBN wheels, buffing compound for stainless steels, polishing mechanisms for granular media, material removal characteristics in computer-controlled ultra-precision polishing, and polishing characteristics of polycrystalline ceramic laser materials. A lively discussion of the presentations was part of the meeting. In the laboratory presentation session, an overview of the S.M. Wu Manufacturing Research Center at the University of Michigan, USA, was given. The success of the 2016 keynote paper, “Abrasive Fine-Finishing Technologies,” was acknowledged. The progress of the 2017, 2018, and 2019 keynote papers was presented, and the contents were all approved. It was also approved that the above-mentioned keynote papers (2017, 2018, and 2019) be forwarded to the Liaison Committee as the STC G future keynote papers. Mr. Aurich, Chairman of STC G, encouraged the audience to present contributions in the next winter meeting in Paris in February 2017. Any abrasive-related topics will be welcome.
