How do you calibrate a custom made tip?

[BSchwark]

I need to use a tip for a new part and the only way I can get it is to use a knuckle to achive the odd probe position required.
The knuckle is in the PcDmis probe library.

How do compensate for the different angles or location each time you may have to set it up again for that program?
Can this be set up to be part of the DCC quailification with a probe rack system?
Can you use this probe to do offline programming?

I have built new and different probes for my probe file but none that were set with the knuckle or a 5 way that was not square to the axis.

Thanks for the ideas.

If I understand you, you are using the knuckle to index to an angle in between the 7.5 degree increments your head will index to, Or you do not have an indexable head and are using the knuckle at an angle to the machine axis to be able to access a feature. I either case I think your only option is manual calibration.

I use a 90 degree knuckle, but I square it up to the y axis of the machine, and it calibrates fine with the regular calibration routine. And yes, I can send it to the rack and retreive it w/o any problems.

I will be using an SP80 and can use the probes available in the probe file. But I have to creat a probe/s that has a compound angle. And looking for options especially for offline programming.

Well, you could try tech support. I do not remember seeing anything on the board about compound angle tips. I still think manual calibration is probably your only option. Please post whatever you may find out from tech support if you call. Sorry I can't be of more help here.

I also use a knuckle and I think to square it up to the y like Wes is talking about you rotate the knuckle angles. I think to square to the y it is 90 and 90. I guess it could be changed to whatever you want. I am not sure about the calibration but if it looked like the picture when you build it, it should calibrate.

We have a knuckle also, squared to the Y axis. I did perform a manual calibration the first time I qualified it, but after that, and with it not being torn down (change rack and dedicated module) it calibrates fine now. (generally .0001-.0002" deviations)
Once you calibrate it, manual the first time if needed, you should be able to re-calibrate it with dcc. The second set of calibration numbers will be taken from the first calibration and you should get better numbers than the manual hits.

Build your probe in the probe utilities. After you select your knuckle, double click on the "CONNECT: (Your knuckle name) and the "Edit Probe Component" window will come up. There will be a field for "Default rotation angle about connection." This is how you can manipulate the angle of not just the knuckles, but any stylus / attachment.

Play around with it and you should be able to get what you need and the machine should calibrate it.

Erickso,
Good ino to have. Rep to you.

What James Said. I will give you rep too and thanks for the info.

Orientation of most stars/knuckles has been, I believe, 1 = straight, in line with A0B0. Position 2 = pointing where A90B0 would be. Then rotating clockwise (looking at table) from there. However, as you have probably run into, DCC calibration is difficult. Go with Wes's suggestion of manual calibration. This would reduce the number of beers it would take to recover, and increase the number of beers you get to enjoy.
