Tapmatic on CNC mill?

[alanambrose]

Well I can't imagine it's that hard as those things are meant to be used with a normal meat-driven pillar drill. It would be nice to find someone who had actually done it though...

You can see the g code around 7:00 in the vid. It's fairly simple I suppose. Being a Mercan, the units are inches:

S1000 (1000rpm in his example - he's not paying for any breakages)
(goto x,y hole position)
G1 Z-0.25 F12.5 (feed down to 1/4" below the surface - it started 1/4" above the surface from the previous operation)
G1 Z0.25 F25 (retract back to 1/4" above the surface)
(goto next x,y hole position)

etc

The tap he is using is a tiny gnat's cock thing with 80TPI ie 12.5 thou pitch, so at 1000rpm, the feed rate needs to be 12.5 (inches per minute). And the retract feedrate is twice that ie 25 (inches per minute).

I suppose the way to do it may be to write a little macro like the above and call it up using the manual NC option within Fusion CAM for each hole position? I don't want to manually type in the coords but I can't see how to make it happen from Fusion.
