Revo and PC-DMIS

...get a straight answer from Renishaw on what the accuracy of the revo head is, in full scanning we were seeing up .0015 (inch) deviations.

Running a Revo, Renishaw controllers, I++ through UCCServer. Software on top of that is mCosmos.

I pull loose R&R at .0004" potential error and uncertainty running 10 parts, three times each with three people.

When I iterate the alignment, I get .00015" potential error in R&R.


That's an order of magnitude smaller than you are seeing. Not sure why, though.


My R&R's do scanning, touch probing and head touching.


I'm not doing blades, but I have it for inducers with helical vanes for pulling fluid up into pumps. Those are five axis scanning, but I don't run it anywhere near as fast as on the website demos.


Also, since it is functioning full five axis with "infinite" angles from single qualification, I LOVE it.

Scanning Ø.250 holes that are 8" deep in a manifold with infinite angles is WONDERFUL! I know when a drill is walking and where it is walking to.
Production hates that I know that, but I love it!

The Revo stuff is LONG. shortest probe is attached to a 175mm long holder, so if you have 20mm past that plus the laser that does the contact detection, you are almost 6" away from the ram at A90.
Want to use A90 B90 and A90 B-90, you need 12" on the sides of the part for clearance (6" each side) plus room for the ram.

Also, when I five axis scan fast, I can feel that massive slab of granite vibrate from the inertia. Mitutoyo (at least at the time) believed this was the smallest machine they wanted to put the Revo on due to inertia and swing around a part.

I know there are people doing Revo's on granite bridge machines, but I'd be worried about room around the parts still.
