wrist calibrations

got 3 probes in this program

first two use the sphere in its normal straight up orientation. first probe is "yes DCC hits to locate tool". second is ""no".

so far so good... this i need to calibrate this monster... and a few more like it...

my questions are... "how will changing the sphere orientation to the horizontal position change the qualification?"
"how will selecting "Yes, manual hit to locate tool" influence the measurements"
"how on earth did i get here?!?!"

also, i cannot trust the machine to qualify these as a group because it tries to "go home" after each calibration by going straight up in Z...

thoughts?

You must use two different qual-tools, even if it is the same one in a new orientation. in orientation 1, master probe (A0B0) is YES it moved, then calibrate all others that you can in that orientation. Then change orientation, change to the other tool setup, then with the SAME master probe, at A0B0, tell it YES for moved, then change to the new probe setup and calibrate with NO

got it... the important part being that the last probe is still referencing the same master probe.

I'll have to restrict the probing arc the second time the master probe references the sphere (because the sphere shaft is in the way now that its horizontally oriented)

should i also restrict the probing arc the first time the master probe references the sphere?

is yes, should i also use the same restricted arc for the second probe??

just to refresh, there are 3 probes in this program, the first two use the vertical sphere, and the third uses the horizontal sphere in the photo

thanks again for all the help. i really appreciate it

I an only tell you the correct 'process' not how to implement it as I have no racks and do not change probes in a program. Both 'unique' tools MUST be located with the same 'master' probe (YES) and all other tips get 'NO' for calibration. Yeah, expensive, but maybe think about getting a second master then both can be setup at one time, then you can 'find' both with the master probe, then simply select the needed tool for all other tips. Pcdmis does have 'some' smarts built in for probe calibrations, can you put the tool on a 45 and get all the probe to calibrate at once?

no, the 45 wont do it. it will for a couple wrist angles for that tiny probe, but not all of them.

also, we have spare reference spheres here... we could set up the fixture in the photo with dedicated spheres...

i was thinking that also, just put it in the 45° position...

yeah... it'll still hit the shaft...

and anyway, we dont have a 45 position on this fixture... got a 30/60... but no 45

there should be an angle portion on that cal sphere standoff you go there, should be on the opposite side of where you have it now at 90°. maybe it is 30°, i always thought it was 45°
