摘要/Abstract

摘要：


采用优质天然金刚石对研、精磨和钎焊工艺制备单颗粒金刚石磨具,用于研究陶瓷等硬脆材料磨削去除、砂轮磨粒磨损及工件表面损伤形成机理。通过扫描电镜获取金刚石磨粒尖端图像,运用灰质化、直方图均衡化、中值滤波、二值化分割及Canny算子预处理并提取磨粒尖端轮廓边缘。在Photoshop软件中测量图像标尺占据的横向像素数目,绘制不同尺寸的圆形与磨粒尖端轮廓线条内切,多次操作后选择最大内切圆。统计该内切圆半径对应的像素个数,利用代数学基本原理即可求出最大内切圆半径。该方法不依赖专用的小曲率半径精密测量设备,具有较高测量精度与可操作性。

Abstract:

A single diamond wheel was machined and prepared by the techniques of grinding, precise grinding, soldering and brazing with natural diamond stuff of high performance, in order to investigate the removal mechanism of hard-brittle materials, as well as the principle of the abrasive particle abrasion and surface damage. Digital images of diamond fore-end were acquired by Quanta 200 scanning electronic microscope, before the grayscale converting, histogram equalization, median filtering, binarization and Canny edge detection of the original images. Afterwards, the pixel number of image ruler in horizontal direction was counted by applying the Photoshop software. And then different circles were made to be tangent internally with the fore-end profile of abrasive particle. Furthermore, the radius of the maximum inscribed circle was defined as the ROC of single diamond wheel, according to a rudimental algebraic theory. The subsequent experiments were validated the accuracy and operability of the new method, which is kindly advised to those special situations being shortage of precise measuring instruments.

Key words: single diamond, hard-brittle material, image processing, radii of curvature(ROC)
