Cutting a curved shape from a block of aluminum

[Rufe0]

I made this gcode for you, it's assuming you have a ball nosed end mill and you have already roughed it out(taken away the bulk of the waste). You need to edit the lines for the spindle speed if applicable(M03) and feedrate (G1 Z0.5 F11) for your machine. Also I assumed a 0.1 width of cut which maybe wrong for your cutter.
