$2(80$ points$)$ Determine the production cost $($material$,$ tooling, and machining time$/$cost$)$ difference for aluminum and titanium cranks for cutting speeds at the low, middle, and high end of the cutting speed range in the chart. Use the following assumptions

$1000$ parts $($right arm$)$

$$75$ per hour for machining time

$.5^{\text{'}\text{'}}$ two flute endmill and finishing with a ${\mathrm{.}375}^{\text{'}\text{'}}$ two flute endmill.

$$50$ per roughing endmill

$$45$ per finishing endmill

No effective limit on RPM or travel speeds

$100,000mm$ of tool travel for the roughing operation

$50,000mm$ of travel for the finishing operation

Aluminum $(n=\mathrm{.}125,C=4000)$

Titanium $(n=\mathrm{.}25,C=1400)$

Stock size options $($blank size of $2203350mm)$

i$.$ aluminum $|$ McMaster$-$Carr

Titanium raw material cost is $9x$ aluminum cost

Hardness less than $32$HRC
