METHOD OF CONTROL OF CIRCULAR GRINDING PROCESS Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: method includes measurement of rotational speed and elastic motions of blank and grinding wheel, as well as grinding force and time. Use is made of electromagnetic coupling to release force closure of blank and its drive. Blank is braked slightly by keeping its rotational speed on preset level which makes it possible to preserve durability of "center-centering hole" connection, and then blank is braked after grinding is completed. Time of the second half of dwelling is selected from condition which ensures preset level of waviness height on surface being ground. The method allows improvement of ground surface quality and automation of grinding operation. EFFECT: enhanced efficiency. 2 dwg
