“…The location of each triangle in the rule viewer represents the determined fuzzy subsets for each input and output, and the height of the darkened area in each triangle symbolizes the fuzzy membership value for that fuzzy subset. 34 From Figure 10, it can be revealed that in case of normal grinding wheel, when the input GRC values for Ra, V , and G-ratio are 1, 1, and 0.3421 respectively, the corresponding defuzzified value of GFRG is 0.767. Similarly, in Figure 11, for rubber tube-pasted grinding wheel, the input GRC values for Ra, V , and G-ratio as 0.556, 1 and 0.406 respectively, generate the corresponding GFRG value as 0.643.…”
