金刚石砂轮表面二维形貌全场测量和分析
Measurement and Analysis of Two-Dimensional Surface Topography of Whole Grinding Wheel
摘要
Abstract
To realize the measurement and analysis of the whole grinding wheel two-dimensional surface to-pography for the effective evaluation of the grinding force,grinding depth,power consumption,grinding tem-perature and machining quality related with the surface,a machine vision-based method was proposed.It com-bined CCD technology with automatic drive rotary technology to realize the non-contact measurement.The size of sampling areas was determined according to the measured object and measured features and they were stitched together without overlap.The image was processed for grain feature analysis and some key parameters were extracted.A brazed grinding wheel was measured using the system.The results:the number of abrasive grains is 1 518,the grain density is 0.5 grain·mm-2,the average area of grains is 0.404 mm2and the average diameter of grinding wheel is 0.359 mm.Experimental results indicate that the proposed method can realize the non-contact measurement of the whole brazed grinding wheel topography and provide some important pa-rameters such as grain number,grain average diameter and its location.关键词
