using automatic progressive die stamping machine. The stamping machine is purchased for an initial cost$-$

plus installation of SAR $700,000.$ Its anticipated life is $6$ Years. The stamping machine operates for a single

shift of $8$ hours$/$day and for five days per week with availability of $100\%.$ Assume $50$ weeks per year. The

applicable overhead rate of the machine is $35\%.$ The cost of progressive die mounted on the machine is

SAR $120,000$ and it is expected that the die will be able to produce $200,000$ washers. The machine is

operated by a worker whose labor rate $=$SAR $\frac{45\mathrm{.}00}{h}r$ and applicable labor overhead rate $=42\%.$ For a

customer order of batch of $400$ washers, the time to set up the machine is $75$ min $.$ Assume the scrape rate

$=0\%.$ The cost of starting blanks $($the material$)$ is SAR $\frac{1\mathrm{.}29}{p}c.$ It takes $42$ sec to load the starting blanks

into the machine in each cycle of the operation. The actual machine operation takes only $8$ sec to stamp

the washer. Determine:

a$)$ Cycle time per washer in minutes

b$)$ Average production rate with and without setup time included in $p\frac{c}{h}r$

c$)$ Determine the equipment cost rate in $SA\frac{R}{h}r$

d$)$ Cost per washer produced in SAR$/$pc
