Abrasive paper wear degree quantification method and abrasive paper service life prediction management system

Abstract

The invention discloses an abrasive paper wear degree quantification method and a service life prediction management system. The quantification method is based on an abrasive paper abrasion physical model, wherein W is abrasion loss, F is grinding pressure, V is abrasive paper rotating speed, T is grinding duration, and k, a and b are undetermined parameters. An objective wear end point is defined, multiple groups of pressure and rotating speed combination experiments are designed, an off-line detection technology is utilized to judge the end point, grinding duration Tij is collected, and then model parameters k, a and b are solved through fitting. The invention further provides a service life prediction management system. The service life prediction management system comprises a parameter library for storing model parameters, an online monitoring module for collecting F, V and T in real time, a cumulative wear calculation module for calculating the cumulative wear loss West and an early warning module for giving out early warning when the West approaches or reaches. According to the method, subjective experience judgment of the abrasive paper wear state is converted into objective quantitative evaluation, and accurate prediction and active management of the abrasive paper service life are achieved.
