You have been requested to write a g$-$code program for a $CNC$ mill to cut out the following part.

This part will be cut from a piece of aluminum that is ${6\mathrm{.}000}^{\text{'}\text{'}}$ wide ${6\mathrm{.}000}^{\text{'}\text{'}}$ long ${0\mathrm{.}500}^{\text{'}\text{'}}$ thick.

For this operation, you will be using a $0\mathrm{.}250"2-$fluted end$-$mill. The Datum point is $(0,0).$
