Characterization of Wheel Wear in High Depth of Cut Grinding

High depth of cut grinding has attracted special interest as a means of increasing productivity. The surface plunge grinding at high depths of cut to 150 um has been performed for soft and hardened die steels. Through the experiment, the wheel wear rate, the actual metal removal rate, and grinding ratio were determined for increasing metal removal rate, using various wheels of different wheel grade, grain size, and grain type. Also, grinding fluid effect was investigated. In special, the characterization of wheel wear was made in detail,and.discussed in related to grain fracture or bond fracture.
