An AX ceramic compound has the rock salt crystal structure. If the radii of the A and X ions are 0.094 nm and 0.208 nm, respectively, and the respective atomic weights are 22.2 g/mol and 73.7 g/mol, what is the density ( in g/cm3 ) of this material

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.
