what are the three mechanisms of grinding wheel wear

Grinding wheel wear

Grinding wheel wear is an important measured factor of grinding in the manufacturing process of engineered parts and tools. Grinding involves the removal process of material and modifying the surface of a workpiece to some desired finish which might otherwise be unachievable through conventional machining processes. The grinding process itself has been compared to machining operations which

Chapter 26 Abrasive Machining and Finishing operations

ME 383 Exam 3- CH 25: Grinding and Other Abrasive

What are the three mechanisms of grinding wheel wear? The mechanisms are (1) grain fracture, in which a portion of the grain breaks off during cutting; (2) attritious wear, in which the grains become dull during cutting; and (3) bond fracture, in which the grains are pulled out of the bonding material.
