Given

$4\mathrm{.}1\mathrm{.}1$ Workpiece material: $6061$ aluminum

$6061$ aluminum is in VDI $3323$ group $21$

$4\mathrm{.}1\mathrm{.}2$ use Haas P$/$N $03-2065$ as the end mill for all milling operations.

$4\mathrm{.}1\mathrm{.}3$ the part reference zero $($PRZ$)$ is the upper left corner of the part, not the" machince home" position$($point $1)$

Use Haas P$/$N $03-2065$ as the endmill for all milling operations.

Exercise $1$

$5\mathrm{.}1\mathrm{.}1$ Use the part drawing $($shown below$)$ to

create a G$-$code part program.

$5\mathrm{.}1\mathrm{.}2$ Use your "Speed and Feed Calculator"

Excel file from Lab #$2$ to aid in calculating the

speed and feed rates required.

$5\mathrm{.}1\mathrm{.}3$ Perform sample calculations in section $10,$

below. This allows partial credit to be given if the

solution is not correct.

$5\mathrm{.}1\mathrm{.}4$ Use the G$-$Code table, below in section $9,$ to

record your G$-$Code.

$5\mathrm{.}1\mathrm{.}5$ To the right of your G$-$Code, record the

function of every word within the block, except

the blocks with dash marks $($we have not covered

these functions yet$).$

$5\mathrm{.}2$ Exercise $2$

$5\mathrm{.}2\mathrm{.}1$ After creating a part with the part program from part $1,$ in section $5\mathrm{.}1,$ above, you measure both width and length of the part as $0\mathrm{.}008"$ oversized. After further investigation you discover the endmill was resharpened, which results in an under$-$sized cutter diameter versus nominal.

$5\mathrm{.}2\mathrm{.}2$ Rewrite the G$-$code to adjust for the undersized endmill diameter. You may neglect the speed and feed impacts from the diameter change. Describing the function of each line of G$-$code in part $2$ is not necessary for excersice $2.$

$5\mathrm{.}3$

$6\mathrm{.}1$ what is the format of a part program name $?$

$6\mathrm{.}2$ what two "words" are used to change a tool with an automatic tool changer?

$6\mathrm{.}3$ what is the purpose, similarity, and difference between G$00$ and G$01$ commands?

$6\mathrm{.}4$ logically$,$ why is M$08$ positioned in the block sequence it is in$,$ rather than eariler or later? Could it be eariler in the program? Could it be later in the program?

$6\mathrm{.}5$ did you adjust your feed rate from points $5$ to $6$ and $10$ to $11?$ How much, why $?$

$6\mathrm{.}6$ did you have to perform additional position calcuations for position $8,9,12$ and $13?$ Why?
