speed, feed rate, drill diameter, and amplitude. The dynamometer was used to mea-

sure the force and torque during drilling. Statistical models were developed, aver-

age maximum and minimum forces came out to be 22.9 and 10.08 N, respectively,

whereas average maximum and minimum torques were 5.937 and 2.501 N mm. it

was concluded that RUM exerts less force and torque in comparison with conven-

tional drilling and produces almost no cracks on the machined surface. It was seen

that force and torque decrease with an increase in speed and amplitude while they

decrease with a decrease in feed and diameter. The rotational speed came out to be

the most inuential parameter among all t
