Q: Is there anyone using a Faro arm for part layout or accurate work? Not your basic .002" stuff, but anyone got accuracy to use on part layout or aide in cmm program correlations. Trying to get away from surface plate layout.
Got the specs right here. Even Faro's best arm (Quantum Series 6ft length) has a volumetric accuracy of .0009" for a six axis model, and .0011" for a 7 axis, and for single point repeatability it's +/-.0006" on the six axis. The technology's getting better, but it's not there yet. The Romer Infinite 2.0 is roughly the same for the 6 axis model, and a little worse in the 7 axis.
We use our Romer's for part layouts on parts with +/-.010" tolerances and above only and leave the tight stuff (fixture layouts, more accurate parts) to the DCC machines.
