There are 3 seperate jobs to make this part.

Roughing 01 uses a 1/8" flat 2 flute endmill
Finishing 02 uses a 1/8" 4 flute ballnose
profile 03 uses a 1/8" flat 2 flute endmill to finally cut out the part.

The roughing is a horizontal roughing and the finishing is a parallel.

Remember tool tip zero is actually the bottom of the work.

This job is ment to be cut out of a .2 inch thick piece of aluminum approx 3x3 inches

Its a heatsink for a luxeon star style led package.

Future revisions may speed up the parallel finishing as it removes very little material.
Also remove the parallel finishing from the bottom of the hexagon as it really does much to defeat
its heatsink ability by making a series of tiny grooves acrosss it.  Its hard to get a good thermal connection to this.
