$\%$A sketch of the workpiece with the main dimensions of the features to be machined is shown in

Figure $1.$ The stock material is $441$ inches, with all sides previously processed to the final

dimensions and finish. The features that need to be machined are:

Four $1\mathrm{.}21$ inch pockets, $0\mathrm{.}5$ inch deep. T$01$ is used for this operation $(0\mathrm{.}5$ inch flat end mill$),$

with the spindle speed $5,000rpm,$ feed rate $60$ ipm $,$ peck feed rate $5$ ipm $,$ depth of cut $0\mathrm{.}1$ inch $.$

One circular pocket at the center of the plate, $0\mathrm{.}5$ inch in diameter and $0\mathrm{.}2$ inch deep. T$02$ is used

for this operation $(0\mathrm{.}25$ inch flat end mill$),$ with the spindle speed $7,000rpm,$ feed rate $30$ ipm $,$

peck feed rate $5$ ipm $,$ depth of cut $0\mathrm{.}1$ inch.

Four channels $($runners$),0\mathrm{.}15$ inch wide and $0\mathrm{.}1$ inch deep. They connect the central circular

pocket with each of the rectangular pockets, and blend into them with the $0\mathrm{.}05$ inch radius. T$03$

is used for this operation $(0\mathrm{.}125$ inch flat end mill$),$ with the spindle speed $8,000rpm,$ feed rate

$20$ ipm $,$ peck feed rate $5$ ipm $,$ depth of cut $0\mathrm{.}05$ inch.
