    Just thinking out loud here.

    What about, in the case of machining a square window in a plate, first remove enough material on one side so the material to be chopped off can move, then chop it off...

    I'd suggest starting values for a general HSS drill of Vc12 .15F for that diameter.

    Meaning around S245 F37 by what I gave you, would suggest S260 F40 instead.

    The F is in millimeter by minute...

    Kennametal makes great tools for alloy steel (nonstainless/getting mad not knowing the right English term.) Their SC drills are excellent for P*, their face mills likewise.

    ... and mine creates the character grid coordinates by a loop, so not dependant on that, but on the other hand I cheated with G52.

    Should rewrite that but hell it's working...

    Well, mine can at least set height.

    How much G-code do you know? I can post mine if you wanna tinker with it to suit your needs. Isn't really rocket science, it's just tedious coding all the...

    Swiss tool company. Very good tools, very expensive. For example we have an insert mill from them using HSS for finishing. I'm saving those inserts we have for special cases because I know our boss...

    Agree in a sense. If you suffer tool breakage continuously with carbide the cycle time is pointless if you spend the same time replacing tools. Expensive tools.

    If mass production on the other...

    I wouldn't use a 3/16 tool, I'd use a 2/16 one and spiral path it.

    Thanks for the kind words, not sure if I deserve them. ;)

    First off as far as I am aware I do not do mission critical taps, as in if it fails it could kill someone. Simple rule is if the hole...

    It's hard for me to really say because I don't often run series of thousands of parts and I haven't broken a tap using this type of cycle. However, I think the last job batch was 150 parts of...

    Well... Funny enough I think precisely spiral taps benefit the most from peck tapping through breaking the chips.

    With a European Standard technical drawing of the parts, one that didn't try as hard as it could to be obnoxious, I'd do it in, say, 20 minutes in Notepad if...

    It's not how fast you feed, it's how fast you change direction.

    Try first entering G8P1 see if the machine complains.

    Then G05Q1 same.¨

    After that run a high resolution macro with each and...

    Thanks for that data page, haven't seen that before, but that seems to be for ramping. I was hoping for recommendations specifically for slicing at a constant Z with a low areal depth of cut either...

    Again that's a bit spartan. Maybe I don't understand. How would I find proper RPM and F for a 1mm Ae with this tool and that chart, and would that be a good idea? What would be better?
