Abstract

The invention provides a calibration device of magnetorheological finishing clearance. The device comprises an auxiliary thin sheet, a flexible connecting piece, a signal collecting device, an industrial control upper computer and a magnetorheological polishing wheel, wherein the auxiliary thin sheet is connected with the magnetorheological polishing wheel through the flexible connecting piece, and the auxiliary thin sheet is provided with a first position in contact with the magnetorheological polishing wheel and a second position separated from the magnetorheological polishing wheel; and theindustrial control upper computer is connected with the signal collecting device, one end of the signal collecting device is electrically connected with the magnetorheological polishing wheel, the other end of the flexible connecting piece is electrically connected with the auxiliary thin sheet, and the flexible connecting piece is an insulating piece; and the invention further provides a calibration method of the calibration device based on the magnetorheological polishing clearance. The calibration device of the magnetorheological finishing clearance and the calibration method can realize automatic high-efficiency and high-precision polishing clearance measurement.

Description

technical field [0001] The invention relates to the field of magnetorheological polishing, in particular to a calibration device and a calibration method for a magnetorheological polishing gap. Background technique [0002] Magnetorheological Finishing (MRF) technology, as an optical processing method that has been widely concerned in recent years, has the advantages of high processing certainty, stable convergence efficiency, small subsurface damage layer, controllable edge effect, and high processing efficiency. It has the advantages of wide applicability and no copy effect in processing optical mirrors with large diameter-to-thickness ratios, and has broad application prospects in the field of aspheric surface manufacturing. [0003] The specific principle process of magnetorheological polishing is: the flowing magnetorheological fluid is ejected from the nozzle and brought into the working area by the rotating polishing wheel, and the moving magnetorheological fluid form...
