as i am using weight loss method for wear rate and wear coefficient.

wear rate = Initial weight-final weight/drill time

similarly for wear rate coefficient K= wear rate/ D*S*N (mg/N-mm)

where D= drill bit diameter (mm)

S= Spindle speed (RPS)

N= Thrust (N)

can i use this for wear coefficient K for drill bit.
