Set up and create an NC program that profiles the part in Figure 1 in a counter-clockwise direction: (a) using full circle interpolation (i.e. use the points indicated, above); and (b) utilizes a coolant to flush chips from the surfaces.

The pertinent machining data is: (a) cutter diameter is 0.25 inches; (b) feed rate is 6 inches per minute; (c) cutting speed is 300 surface feet per minute; (d) the tool home position is at (2, 2, 8); and (e) the part home position is at (4, 4, 0), referencing the lower, left corner of the top of the workpiece.
