• 1/8" End Mill Bit that can cut metal
• 1/4" End Mill Bit that can cut metal
• Vacuum table to hold material down flat
• Sacrifice Board
• Metal Screws and such to attach the material to the sacrifice board
• Coolant (we used mist coolant, not sure the brand or anything else. I can get back to you on that. I see that your Haas TM-2P is made for flood coolant)
• CAM software, we used Mastercam last year with success. Our new Computer Integrated Manufacturing teacher has switched us over to EdgeCAM, we'll see how that goes
• Someone with experience. If you get wood-cutting bits (1/8" and 1/4" are fine), which I would recommend getting for training, have someone use the machine all first semester as much as possible to learn it and learn some of the shortcuts and such on the machine

That last one is big, even though it doesn't sound like it. The more people you get to use it during the offseason and the more hours that you have people working it during the offseason, the more parts you will feel comfortable with being cut on it. Also, the more people you have on it, the more efficient your team can be in cutting on it, since one person could run the machine, and the others that can CAM will be making the tool paths.

If anyone has any more questions feel free to ask. I haven't read through the entire thread as of right now, but I'll try to get to it.

What did you do for your vacuum set up? Our team made our vacuum from a board with a ring cut around it for a o ring like thing, then we used 2 shop vacs to pull the material down. We've had some success using it with plywood, but we just can't get aluminum to stay still.
