Design a PD controller so that the peak time of the PD-compensated system is reduced by a factor of 1.5 from the peak time of the gain-compensated system, and the damping ratio remains at 0.6. Determine the location of the compensator zero, calculate the corresponding overall gain KP and calculate the resulting s

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
