    It sounds like the tip is failing upon entry, and looking at that grind my guess is that it has no support because the outer isn't in the hole yet. Definitely try a spot drill, this way when the...

    I cut my teeth on 2 of those old Monarch lathes. Built in 1941-ish. They were rock solid even in 1989.

    So your groove is a basic [ shape?
    What littlerob1 is suggesting and what I've done also is to basically groove it in the style of a facing toolpath.

    I'm a Sandvik guy, but when it comes to grooving, it's hard to be better at it than Iscar.
    That being said, any top brand will have capable tooling.

    A lathe can usually do this in a fraction of the time a mill can. (if it has any type of profile other than just a square groove)

    We paid $6,200 for the 16k Dual Contact spindle replacement.
    For reference, a spindle on our Okuma genos M560V is pushing $30k.

    I believe you can't run Big Plus in a non-Big Plus spindle.
    BUT
    you CAN run a regular Cat holder in a Big Plus.

    It's definitely pushing the limits for sure. Stubby holder, dual contact, etc..
    We've slowly crept up to those parameters and found a sweet spot.

    I was referring to the "start" notes. Meaning the datum is shifted and not the edges of the part.

    I agree with the above, your control is unable to process lines of code quickly. Your best bet is to just feed it slower and/or make your moves longer.
