Eric,
The "DNC" method as was mentioned will work, but be subject to the speed limitations of the RS232 port. For very fine point to point programs you will suffer from data starvation. The effect of this is the appearance of a cap on the feed rate, but actually you will have dwells. This can result in poor surface finish as well as increased cycle times.
A couple of alternatives:
Depending on how big the files are you might be able to purchase more memory from fanuc. I think they call it bubble memory and I recal it was a couple grand to get to 64K 10 years ago.
Regarding the DNC method, you set the controller up as though it was reading from paper tape. That control probably has a swich that says "Tape" right on it. What I did was set up my DND server on an AB switch to the RS232 port.
There are also BTR units that emulate the Tape reader and have some Ram in them. Again these use the RS232 port as far as I know.
You may be able to have the programmers use the "Filter" option in Mastercam to generate programs that have G2 and G3 arcs that aproximate the G1 points resulting in shorter code (and usually better looking parts). The machine needs to suport G18 and G19 coordinate systems and the Mastercam post needs to suport it as well. If it is a new mastercam installation with posts based on the MP fanuc post it will.
