Abstract

The invention discloses a roundness measurement method based on two sensors. The measurement method utilizes two sensors to detect the radial runout signal of the workpiece to be measured, and based on the radial runout signal, a flip method algorithm and a two-point method algorithm are combined. The estimated value is quantified and further confirmed by frequency domain hybridization, so as to ensure the accuracy and precision of the measurement result.

Description

technical field [0001] The invention relates to the technical field of roundness measurement, in particular to a roundness measurement method based on two sensors. Background technique [0002] With the help of single-point diamond lathes, rotary parts can obtain nano-scale surface processing quality, so they are widely used as core components, such as bearings, plungers / cylinders, optical mirrors, etc. The roundness error of the standard rod configured by the American Lion spindle measuring instrument is less than 50 nanometers. The surface processing accuracy of the hydrostatic bearing is related to the static stiffness, load capacity, service life and rotation accuracy of the spindle; with the reduction of the roundness error of the bearing, the rotation accuracy of the spindle can reach nanometer level, and there is almost no damping force. The surface topology of an optical lens determines its focusing ability, image resolution, and imaging quality. Due to the high ou...
