The value of RPI and RMCI are also presented in the Table. All the predicted instantaneous cutting rates are in similar trend with MICR (Figure 2). A summary of the influential parameters used in these indices are enumerated. Table 4 – RPI, RMCI, BICR, GICR and CICR from respective Indices (Dey and Kumar, 2021) S.No .
