Manufactures Recommended SFM and IPT

Answered

I have limited experience at CNC machining in metal.  I’ve had a CNC Router for 15 years working wood.  I am struggling a bit with speeds and feeds for metal.  In Gwizard, it wants manufactures recommended SFM and IPT.  I don’t tend to have these numbers.

For instance, I purchased a Tormach Superfly with the polished inserts for aluminum.  I assume I should set it as 1 insert facemill and the diameter to whatever the fly cutter is set to.

On the Tormach site, there is no information on these manufactures recommendations.  Gwizard throws some numbers in for these parameters.  Are the Gwizard numbers typically good enough or do you really need to research these parameters?

Terry, entering the Mfg’s recommendations are totally optional.  You can run with G-Wizard’s defaults which are on the conservative side if you don’t have the numbers or don’t want to take the time to look them up.
