摘　　要：通过对工程陶瓷磨削加工试验得到的表面图像进行观察和分析,对表面损伤情况进行分类。运用计算机数字技术对表面图像进行图像增强、平滑去噪、中值滤波、细化等一系列的处理后,对加工表面所出现的微裂纹和脆断凹坑进行识别和提取,最后采用表面破碎率这个量化的指标来评价图像表面的损伤程度及其与加工参数的关系。The surface damages were studied and classified by analyzing the surface images of engineering ceramics from grinding experiments. Using the digital image processing technology, the surface images were firstly processed and treated including image enhancement, smoothing denoising, median filtering and refinement. The micro cracks and fragmentation areas were identified and filtered from the pre-treated images. The degree of damage on the grinding surface and the effects of processing were analyzed according to a quantity criterion.
