    Those Kennametal parameters seem pretty "Magical" indeed, in 4140. Not saying it can't be done, but I do think everything has to be totally squared away -- toolholding, workholding, everything.

    I'd say it depends on what sort of parts you mostly make. There's this:

    The former is (well, could be) <100 lines with all the preambles and comments. The...

    Eh, maybe a 5/8" ;). 1/2" with 2x .030" corner radii won't clear a .470" wide path.

    Since the part is so narrow, I think I would rather use a corner-radius endmill.

    G277 with a Q does a full-retract peck tap.

    Like so:

    G99G277Z-.8952R.2875J16.Q.5S500

    If you omit the Q, it does a regular tap cycle.

    Regards.

    Probably because that's the nearest commonly available drill size. "M" would be slightly less than 60% thread, IF it drilled right on-size. I usually see a little oversize hole in 1018 -- if the "M"...

    I'm looking at my tooling for M8 (standard 1.25mm pitch) form tapping, and am having some trouble deciding what drill to use. The form tap drill size chart I use says that a 65% thread...

    How about toolholders? I see the CM-1 uses 20-taper, and the Neo uses proprietary Datron (AFAICT). Either of these will restrict your choices of suppliers, but if you are considering >30k RPM, you...

    They don't like 240V 3-phase like you would get straight out of a PhasePerfect or RPC. Typically you will need to buck down to 208-230V.

    At that quantity, it might make sense to have someone run them in a VMC. Machine a couple high-density fixtures and do them 50 or so at a time.

    It might depend on the type of chip. Straight flute endmill makes mountains of fluffy whiskers that are hard to get moving. A segmented or wavy/corncob rougher fixes that.
