part profile is geometrical deviation or error. Then this geometric error is converted
into root mean square error (RMSE) using Eq. (1).

The surface roughness is measured using Mitutoyo’s SJ-310 surface roughness
tester (as depicted in Fig. 7). Surface roughness is measured at four places in inner
