    If it's profile to datum A, that is correct. Simple profile (to itself, basically), no.

    The default software (can't recall name right now) is actually not that bad. I would think it's less than $5K, since it's pretty basic.

    The biggest issue is part of what you stated above: the...

    In Europe? Believe it or not, for micrometers, I dislike Mahr (they don't have very good resolution or feel). Etalon are always good. Never had a chance to use Bowers OD mics, but their ID...

    Great book. As far as I know, even today, lapping/scraping surface plates in sets of three is still the best method, material must still be incredibly stable to start, and must be processed and used...

    "Unless otherwise specified, the limits of size of an individual feature of size control the form of the feature as well as the size." MIL-STD 8 1949, (the grandfather of ASME)

    Easy and reliable? Mahr Federal makes a really good series of dial indicators with HUGE, easy-to-read dials, coolant/shockproof, the whole works. Made for applications like this. 256048

    Most employers are somewhat open to entry-level positions for inspectors with some CMM experience. Calypso software is REALLY intuitive and easy to pick up. I've trained dozens of people on...

    Thickness may not be less than .5000, nor greater than .5006 at any point regardless of how it's measured.
    ASME rule 1 (comes in various flavors, but all standards cover this) states that, unless...

    Technically, no radius at all would be acceptable. If you're talking about a machined fillet radius, that is, of course, impossible.

    O-inspects are fantastic machines. I've written programs off-line that ran completely fine, having never seen or touched the device, mostly to the credit of Calypso software. Not enough experience...

    The FARO can not, in a million years, measure 8 microns accurately, the manufacturer grossly overstates the capabilities. They're OK for, say sheet metal work, or sand castings, but not precise...

    The FARO arm is a bit flimsy, Romers are a bit better built. However, if you're only laser-scanning, the FARO may be OK for your application.
    If at all possible, get Polyworks, it's pretty...

    Sadly, PC-DMIS is, by far, the worst CMM language I have ever used (out of about a dozen). PC-DMIS is buggy, makes more types of fundamental calculation errors than i can elaborate on...

    Polyworks is less buggy than PC-DMIS, but won't report datum shifts (as of about a year ago, they may have fixed that by now). PC-DMIS reports datum shifts, but makes a fundamental error in the way...

    Don't get a FARO arm, they're piles of garbage. Get a Romer, and run on either PC-DMIS or Polyworks.

    I don't know. I'm 52, and am still amassing a collection myself. Perhaps, simply trade for a different style of machine, smaller and easier in later years. Horological (clock and watchmaker's)...

    Try a tie rod end puller and whatever round stock (socket) can get to inside of chuck. Just check first with mirror, on off-chance that it uses a reverse-thread screw, like hand drills.

    If memory serves, only the GO side of the tolerance band changes on A threads (the NOGO for B threads) with tolerance classes. A 2A and 3A NOGO are the same, nominally.

    For comparative measurements to gauge blocks (or Cadillac gauge). If everything is square and in good shape, sounds like $200 is a good price.

    Reflex actually isn't that bad. You just have to get used to the way it wants you to think (in 2D terms, the way PC-DMIS used to be a long time ago).

    Depends on your knowledge, skills, years of experience, region, and previous pay history. I believe California/Minnesota/Michigan are all in the $20-$45/hour range depending on the other factors.

    In real life, the error will be negligible, provided you're not probing anywhere near 0° (head-on).

    Stay away from that Mitutoyo PH14. Both optical, and mechanical junk. Obviously, you need something used. Micro-Vu is good, as is Jones and Lampson, Scherr-Tumico etc.
