  • Romer vs Faro

    Any thoughts as to the benifits of Romer over Faro? My shop is thinking of getting a portable CMM and I'd like to get some imput as to which you think is better. Also do you have any suggestions in gereral for what to be careful about with portable CMMs?

    The Faro Arm is pretty good, We got one about 2 years ago. My biggest fault with the Cam 2 software is that it doesn't have feature recognition. Other than that it is pretty user friendly. We have only had one issue with ours, the encoder went out on one of the axis', they turnaround time for repair was about 2 weeks. There are 2 other companies in this area that we do work for and both of them have had trouble with encoders going bad. As for the Romer, I played around with an old one at a customers place once but to compare it to the newer model Faro wouldn't be comparing apples to apples.
    If the need arose for another portable I would definetly look at Faro again, but wouldn't limit myself to that choice.
    I might not love my job, but I love the ones it feeds!

      We have/been using a Faro arm (Silver)with PcDmis and have found it very useful out on the shop floor for jigs, dies etc.Was purchased about 4 years ago and doesn't have the Infinite Rotation that the Romer has now.

        Version 4.0 of PC-DMIS has made a nice interface and new algorithms for use with manual arms. Been training and supporting on the Romer for a while, a very nice product. Wireless is awesome. Also remember, you can by Romer and PC-DMIS from the same company, and get equally supported by both.

          we recently bought a faro gage arm. as far as using it if it used in the way it was designed for it works great. if you are normally used to running PcDmis i would advise against the Faro software it is too limiting and the tech support we get fro Hexagon is 10 times better than at Faro. Just one programmers observation. i would also advise doing a correlation study between the arm and your normal cmm and see the difference it would have on using it in the manufacturing area. hope this helps Scott Bean

            Thanks for the replies. We did get the Faro. I haven't even had a chance to touch it yet, we're so busy right now. I would like to do a correlation between the Faro and one of our standard CMMs.

              Get to play around with it yet? Correlation study? Lemme know what you think about it, they're coming over for a demo in a couple weeks.

              Also Scott mentioned not going with the Faro software? What other software is there, and is one regarded substantially better? Anyone?

                I didn't get a chance to do the correlation study yet, but the other guy who is learning it checked a 1/2 inch gage ring and found it within a few tenths. I want to check some distances betwen holes or something like that. We are severly under staffed here.

                Coot mentioned that PC-DMIS will work with it.

                  We are using a FARO arm with Geomagic software (Studio & Qualify). We did a correlation of a scan to the same part run on the CMM - very close, <0.02mm.
                  This may not be close enough for your parts, but since we make and measure raw sand castings, this is fine for us.

                    Ya, with all the issues I already have with PC-DMIS though, I'm not too excited about getting it for a Farogage. Not to mention Hexagon is probably charging an arm and a leg for the software.

                      Good Morning,
                      Contrary to sales pitches, the Faro is not so indestructable. The scales or encoders are glass and fragile. Take caution to not let the arm bump any hard surfaces. We are down due to an encoder problem and I spoke with the techs and found that the encoders are glass and to repair them, is to have the problem section replaced.

                        Scott was right, the CAM2 software that Faro comes with is driving me crazy. Just one example is the fact that you can only have one alignment active at a time. This means if you have a lot of features that come off of different datums, then you have to change the alignment print the features in that alignment, then change it again and print those features, etc. You can incorporate all that in a program, but it's still a pain in the rear.

                        Also there aren't any polar coordinates, its all XYZ. If you want to report the angular position of something you have to create a dimension of the angle of two lines that you have to create. It's so cumbersome.

                        Also to have nominals for a feature you have to create a nominal feature to link to the measured feature. If you want to edit the nominals, your out of luck. You have to create another nominal feature and then link the measured feature to the new nominal.

                        I do have to say it works pretty good with a CAD model. You can create your nominal features right from the CAD, but you have to do that before you wright your program so you can link them to the measured features.

                        As for accuracy, if you don't have to articulate the head much it can be pretty accurate. If you use the full range of motion it can be off a couple of thousandths of an inch. It all depends on how many joints you move and how much you move them. It's pretty good for rough castings or laying out a counter top.

                        Sorry for the long post, but the guy who was using the arm just quit so I've been doing a lot with it over the last week and have learned a lot of it's quirks.

                          We have a FARO Laser Tracker with CAM 2 Software, though I have some issues with the software there is 1 huge advantage.
                          New versions cost less then $500.00.

                            As they say below, watch our for sharp blows. The salesman tell you this is a rugged piece of shop floor equipment. About the third trip in for repairs and you will agree it is a piece. . .

                              PC Dmis can only be put on a Faro arm that is at least a year old.
