No wonder that file takes so long it makes one pass at the OD then rapids to a slot makes one pass then rapids to the next slot... then rapids to the holes then rapids to the ID. And wow is it complicated and full of neat code. It would make much more sense from a machining view point to cut each slot fully then move to the next slot then change tools and drill the mounting holes and with a larger end mill cut out the center and OD of the part. The beauty of Lawrence's file is that it is completely configurable.
How in the world do you hold the material to machine ID, OD, slots, and holes at the same time? If I had to make that part and I might one day, I'd drill the holes then mill the ID. Then I'd prepare a mounting plate with a boss the size of the ID then bolt the disk down and mill the slots and the OD. By "duty cycle" does that mean the width of the slot verses the width between the slots?
