(OP)
Does anyone have any tips for the best way to machine LP410A nylon. We have cnc capabilities for the maching. What types of feeds and speeds, cut dry or with coolant, what type of coolant, how many flutes, etc.

RE: Machining LP410A Nylon

You best bet is to get with your supplier of the Nylon and get their recommendations.  A lot of with machining Nylon is in the additives used.

RE: Machining LP410A Nylon

Best thing to do with this stuff is 'anneal' it first. Then it machines just fine, coming off as nothing more than powder. It absorbs moisture, so that makes coolant a bit of a problem, especially if there are any close tolerance features. Machining dry with an air blast is your best bet; high feed, lower speed, very sharp tooling. Onsrud makes a very nice single flute tool for this, though I typically anneal the stuff before hand to eliminate the need for any special procedures.
