Non-smooth probe movement

[rerun_lives]

We have a Sheffield RS-30 Cordax with a retrofit (not up to date) and we are getting linear movements out of our probe when we calibrate. Instead of smoothly advancing around the Tooling Sphere in a continuous circular motion before and after it making it's hits, it move in small jerky linear movements until it gets to its next hit. Does anyone know of a way to change this behavior so the probe travle is smooth and continuous when moving around the tooling sphere. It works when probing circlular features in a program - Odd huh?

There are 2 palces where you have to change this, one is in the F5 setup window (use circular moves on round features) and the other should be in EDIT ~ PREFERENCES ~ MACHINE INTERFACE SETUP, and there you have to turn on the same thing.

You might be stuck moving in squares due to your controler compatability with PCDMIS.

It kind of sounds like you need to have fly mode turned on. My DEA did this very same thing, and it was due to the need for the fly mode option.

It has something to do with the controller design generally from what I was told by my CMM Calibration guy. The cheaper B&S globals need this setting as well.

To activate, go to the Edit>Preferences>Set-up menu and select the Part/Machine tab. Here you will see the box Which says Fly Mode. Usually the radius can be left at the default shown in the small box. Make sure you have your cursor positioned somewhere above the dimensioning format line in the edit window and click the "activate" button under Fly Mode. After you do that, you should be able to click on defaults and have this setting as a default for your programs.

Try this and see if it takes care of your issue.

Criag nailed it, the only controller to date that Sheffield had that supported circular moves was the SMP 400. The MP35 did not. Why you may be seeing what appears to be smooth motion on the measurements is an opened up move tolerance on the features - it is not a true circular move behavior.

I understand that the new universal controller that they will use on Sheffield's (and some select B&S) will have circular motion.

Sorry fellows, nothing seems to work. Matt, I couldn't find what you were describing in the "machine Interface setup" area. Oddly enough before we ever messed around with 3.7 this machine would make smooth circular movements when calibrating. Just another glitch that increases the value of our software I guess.

Which controller do you have?
Which software were you using that showed smooth moves while calibrating your tips?
