  • Grinding of hardened steel for tribological performanceCORE

    Hardened specimens of 52100 and M50 steels are plunge ground with CBN grinding wheels and for comparison conventional aluminum oxide wheels. When combined with the workpiece velocity the material removal rate is obtained from the measured depth and width of each cut. The grinding forces normal and tangential are measured using a dynamometer.
