Question B

$(50$ points$)$

Write an APT program for the profiling of the part in Figure below. The processing parameters are: $($a$)$ feed rate is $50$ mm per minute; $($b$)$ spindle speed is $600$ revolutions per minute; $($c$)$ a coolant is to be used to flush the chips; $($d$)$ the cutter diameter is to be $10$ mm $,$ and $($e$)$ the tool home position is $(0,-1,0).$ Refer to Handout $2$ for examples.

You can define your own point, line, circle geometries. Follow the path from point PO which is the origin, to point A to point B and so forth in clockwise direction. The center of both $AB$ and $HG$ arcs are coincident. $($All dimensions are in mm $).$
