Move probehead angles only

[jleond]

Is it possible to move the probehead angles without calibration? I need to measure deep inside the green cylinder using the rotary table (pattern of vector points to construct some circles) but the probe build is too long and I have not enough travel in Z axis, so I need several probe angles to get inside the cylinder step by step (for example, move above and beyond cylinder center with A-75B0, rotate probe angle to A-45B0 and move again beyond cylinder center and so on).

Thanks!

It’s probably possible. It’s probably not recommended.

[jleond]

Thanks acgarcia!

Can you explain how it´s possible and why is not recommended?

[acgarcia]

Haven’t done this myself but I would make the angles needed to move into the part then once, I’m in, use a calibrated angle to measure the part. Then reverse it out.

It’s not recommend to change angles in a part incase the probe hits the part during a rotation. You’ll have a hard time trying to get the probe out.

As I understand, you can do it if you don't measure with uncalibrated positions.
This that you use to measure must be calibrated.
Maybe you will have a warning saying that the tip is not calibrated, but it's not important !

Thanks Jefman!

If JEFMAN 's suggestion doesn't work, and you keep throwing uncalibrated probe errors, you could create a dummy probe file with the same exact build (and put into the same slot(s) if using a changer), turning off the qualification warning, and use that for the incremental, non-measuring angles. IIRC, you can qualify it offline and it will show as having been qualified once.

LOADPROBE/LONG_BASS_TURD

LOADPROBE/LONG_BASS_TURD_JUNIOR
{incremental rotation}
{incremental rotation}
LOADPROBE/LONG_BASS_TURD
{measurement rotation}
{do stuff}

Thanks RandomJerk!, That´s what I what thinking to do, yes I'm using probe changer.

Or calibrate the tips offline...

Edit:
NinjaBadger posted this below already.

It might be risky but you could simply 'calibrate' the unused tips offline (so they show as calibrated).

The danger is someone uses one of these uncalibrated tips elsewhere.

+1, I will follow what RandomJerk said and only use the dummy probe with thtt specific program, thanks.

I calibrate a slew of angles that I may need before i plunge into the part. I frequently bury the head into cylinders and such, and perform rotations to capture the data I need via discrete points, then use them to construct reportable features.

[jleond]

+1, only that I program offline first, then proof it at the CMM. At least the demon does a pretty good simulation offline.

[Cumofo]

I usually conduct a z axis only pass from bottom to top, then pattern and rotate about the centroid of the cylinder being inspected. (i used the word "inspected", we don't do that anymore, we "validate").

[jleond]

That´s exactly how I do, thanks!

[Cumofo]

Gosh, that felt fuh_King good.
Iz that how the rest of you guys feel when you spill your guts about some mutba_fuh_king secret PC-Demon had you bent over in half backwards trying to figure out so you wouldn't lose your job and have to be homeless or sleep in your car or move back to your in laws again., and finally like by some fuhk-ing God miracle the PC-DMIS Demon produces an acceptable motion input to the controller to gather all those - shizzy-little-fuggin-descrete points you need to construct the shitty"bits of Geometric Parameterization you need to release yourself from this dimensional interface purgatory.
