Abstract: The invention provides a cutter wearing monitoring method and a cutter wearing monitoring system. The cutter wearing monitoring method comprises the following steps of performing longitudinal cutting on the machining surface of a machined sample by means of a cutter, thereby forming a machining trough, wherein the cutter is a single-point diamond cutter with a circular cutter nose; acquiring the coordinate of each drawing node of the machining trough; drawing the 3D contour of the machining trough through the coordinate of each drawing node of the machining trough; obtaining the 2D contours of cross sections of a plurality of machining troughs according to the 3D contour; measuring the actually measured cutting depth DoCm of each 2D contour; performing respective calculation for obtaining the actually measured area SM of each 2D contour; drawing a regression line of DoCM and SM<2/3> according to the actually measured areas and the actually measured cutting depths of a plurality of 2D contours, and drawing the confidence interval of the regression line; determining the sampling point (DoCM, SM<2/3>) of each 2D contour is in the confidence interval, if not, determining a fact that wearing of the cutter has caused limit of service life; and replacing the cutter. The cutter wearing monitoring method has high practicability and high automation degree.
