Grinding burn is caused by excessive heat produced during grinding process. It changes the surface hardness and reduces the fatigue resistance which brings great damage to work-piece [1, 2].Grinding burn is widespread in the field of cylindrical grinding, rail grinding, bearing rings grinding, and so on [3,4,5].Therefore, the detection and monitoring of grinding burn is of great …Grinding forces are a key parameter in the grinding process, most previous studies on grinding forces, however, (i) were regardless of grain-workpiece micro interaction statuses and (ii) could only predict average/maximal grinding forces based on average/maximal cutting depths or chip thicknesses.
