20.500.12556/RUL-138675 Mechanics of self-rotating double-disc grinding process Unlike most double-disc grinding processes, which use forced workpiece rotation, some double-disc processes rely on workpiece self-rotation driven by non-uniform shear forces resulting from partial wheel-workpiece coverage. This self-rotation is poorly understood, with workpiece angular frequency remaining unknown despite its importance. This paper investigates the kinematics of self-rotation via analytical modelling of the moment-equilibrium conditions, derived from experimentally determined specific-energy values. The model showed that workpiece coverage ratio is the dominant factor governing workpiece angular frequency, allowing for the choice of optimal workpiece coverage ratios that avoid workpiece-stoppage and excessive frictional heat generation. The predicted velocity was validated with acoustic-emission measurements. grinding bearing double disc brušenje ležaji dvojni disk true false true Angleški jezik Slovenski jezik Članek v reviji 2022-08-09 10:42:04 2022-08-09 10:42:10 2025-02-26 13:27:43 0000-00-00 00:00:00 2022 0 0 Str. 309-312 iss. 1 Vol. 71 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-04-20 621.7 0007-8506 10.1016/j.cirp.2022.03.033 117677059 Drazumeric...-Mechanics_of_self-rotating_double-disc_grinding_process.pdf Drazumeric...-Mechanics_of_self-rotating_double-disc_grinding_process.pdf 1 61CD1A62DE592A9A8F0270F8E29BD25C 957deefa878e6f23dd480cd8a64f6cee50abe9d05a40a2cedd57327af9aca8cf 544e87c9-17bf-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=159067 https://www.sciencedirect.com/science/article/pii/S0007850622000348 1 df39be8b-17be-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=159066 Fakulteta za strojništvo 0 0 0
