Since this will cause aliasing, an anti-aliasing filter will be applied to x(t) prior to sampling. How should the cutoff frequency for the anti-aliasing filter be chosen, so that the signal that is sampled will not experience aliasing

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.
