Prior to any practical application, brittle material components may need to be machined to a high degree of precision in order to avoid functional breakdown as well as to maintain exacting surface dimensional integrity and retain strength. This usually means grinding in the ductile region. Optimization of the grinding process can shorten manufacturing time and cost and prolong component lifetime. This article reviews the current state of the art of ductile grinding and outlines the underlying science behind pertinent machining events. Engineering aspects of the grinding process will be surveyed, with consideration of wheel requirements and of such variables as grit characteristics, strain rate and temperature. Attention will be given to the fundamental role of removal processes from individual and cumulative microcontacts, using nanoscratch mechanics as the underlying basis for analysis. The critical influence of diversity in material microstructures in determining local deformation mechanisms and subsequent material removal will be highlighted. Practical requirements for optimal ductile grinding will be indicated.

在任何实际应用之前，可能需要将脆性材料组件加工到很高的精度，以避免功能故障以及保持精确的表面尺寸完整性并保持强度。这通常意味着在延性区域进行磨削。优化磨削工艺可以缩短制造时间和成本，并延长组件寿命。本文回顾了球墨铸铁磨削技术的现状，并概述了相关加工事件背后的基础科学。将对砂轮工艺的工程方面进行调查，并考虑砂轮的要求以及诸如砂砾特性，应变率和温度等变量。将关注从单个和累积微接触中去除过程的基本作用，使用纳米划痕力学作为分析的基础。将突出材料微观结构的多样性对确定局部变形机制和随后去除材料的关键影响。将指出最佳延性磨削的实际要求。
