A Method for Measuring the Wear Rate of Diamond Abrasives Based on Image Processing

Abstract

The invention provides a method for measuring the wear rate of diamond abrasive grains based on image processing. First, the diamond abrasive grain image is subjected to median filtering and Gaussian filtering to obtain enhanced diamond abrasive grains aggregated from the median filtering image and the Gaussian filtering image. image, using edge detection and morphological methods to segment the abrasive grain area of ​​the enhanced diamond abrasive grain image, and extract the segmented abrasive grain area image; secondly, perform median filter preprocessing on the extracted abrasive grain area image, and continue to use the edge The detection and morphological methods segment the wear area of ​​the abrasive grains, and extract the segmented wear area image; finally, use the method of regional pixel statistics to calculate the area of ​​the abrasive grain, the area of ​​the wear area and the wear rate of the abrasive grain respectively, and complete the diamond abrasive grain Determination of wear rate. The invention overcomes the shortcomings of manual qualitative observation of diamond abrasive grain wear in the past, realizes the quantitative measurement of the wear degree of diamond abrasive grains, and improves the accuracy and efficiency of the measurement.

Description

Technical field [0001] The present invention relates to the field of image detection diamond abrasive tools, particularly to a diamond-based image processing method for determination of the wear of abrasive grains. Background technique [0002] Diamond tools are widely used in ceramic processing, optical crystal, semiconductor carbide and other hard and brittle and difficult to machine materials. In the process, the diamond abrasive grains and the workpiece and cutting the chips occurring complex, pear farming, scratch or impact interference effects. As the process will result in varying degrees of diamond abrasive wear. Diamond grit has an important influence on the surface quality, process efficiency and tool life are on the surface of the tool wear. In order to avoid premature or abnormal wear of the diamond abrasive grains, to improve processing quality and processing efficiency, extended life of the diamond tool machining, the need to wear diamond abrasive grains is measured...
