Abstract In theory, the chip shape distribution changes with the wearing of a grinding wheel in both sur-face and cylindrical grinding processes. However, the relationship between the chip shape distri- bution and wear has not been verified experimentally and quantitatively under any of the grinding techniques. To this end, in this work, chips from repeated cylindrical grinding processes are col-lected. It is noted that the workpiece surface becomes rougher with each repetition. The images of the individual chips, obtained using a particle tracking system are analyzed, and the results indicate that the proportion of small chips and slender chips, respectively known as melted and flow chips, increases when the grinding wheel is worn, which is in contrast to the implications of the established theory.

利用图像处理技术分析切屑尺寸分布估算外圆砂轮磨损状态

摘要 理论上，无论是平面磨削还是外圆磨削，切屑形状分布都会随着砂轮的磨损而发生变化。然而，在任何磨削技术下，切屑形状分布和磨损之间的关系尚未通过实验和定量验证。为此，在这项工作中，从重复的外圆磨削过程中收集切屑。值得注意的是，工件表面随着每次重复变得更粗糙。对使用粒子跟踪系统获得的单个切屑的图像进行分析，结果表明，当砂轮磨损时，小切屑和细长切屑（分别称为熔化切屑和流动切屑）的比例增加，相反到既定理论的含义。
