$6.$ Consider turning, milling, grinding, EDM, reaming. Which material removal process would be used to create an axisymmetric workpiece with moderately tight tolerances $(\backslash (+/-\mathrm{.}002\backslash$mathrm$\{$in$\}\backslash ))$ and good surface finish $(\backslash (\backslash$mathrm$\{$Ra$\}=24\backslash$mu $\backslash )-$in$).$

$7.$ Consider turning, milling, grinding, EDM, reaming. Which material removal process would be used to create a complex, very intricate mold cavity in a hardened steel block$-$shaped workpiece?

$8.$ Consider turning, milling, grinding, EDM, reaming. Which material removal process would be used to create a shoulder feature with very tight tolerances $(+/\mathrm{.}0002$ in $)$ and near$-$mirror surface finish $(\backslash (\backslash$mathrm$\{$Ra$\}=2-3\backslash$mu $\backslash )-$in$).\backslash (?\backslash )$

$9.$ Consider turning, milling, grinding, EDM, reaming. Which material removal process would be used to create a very accurate size $($e$.$g$.,.\backslash (25+/-\mathrm{.}0004\backslash )$ inch$)$ hole in an aluminum workpiece?

$10.$ Consider turning, milling, grinding, EDM, reaming. Which material removal process would be used to create a simple mold cavity in a mild steel block$-$shaped workpiece?

$11.$ A lathe is set up to turn a stainless steel part $($approx $200$ HB $).$ A depth of cut of $\mathrm{.}2$ inches is planned. Feed rate is to be $\mathrm{.}005$ ipr $.$ The cutting tool will be $\backslash (\backslash$mathrm$\{$Si$\}\_\{3\}\backslash$mathrm$\{$~N$\}\_\{4\}\backslash )$ ceramic, so V$-$speed $($determined from the tool catalog$)$ is to be $1200$ fpm $.$

a$.$ If the original workpiece is a $3\mathrm{.}0-$inch diameter, $6-$inch long cylinder, at what diameter will the tool tip actually cut?

b$.$ How long will it take to complete a $5-$inch long cut $(1$ pass$)?$ Assume $1$ inch in chuck.

c$.$ Calculate the Material Removal Rate $($MRR$)$ in $\backslash (\backslash$mathrm$\{$in$\}^\{3\}/\backslash$mathrm$\{$min$\}\backslash )$ for this cut.
