Hello, I have a question on the reliability of the FaroArm vs. a Romer.
We are considering buying one of these equpments and I have heard that the Faro is known to have a problem with the encoders. I am not familiar with the correct terminology of the hardware of this type of CMS.

If anyone could share their experiences I would appreciate it for it is a big investment and would like to consider all available options. Thanks in advance.

Bump.

Suggestions anyone?

Hello, I have long experience with both arms for the past 15 years.
FARO arms have still bis issues with encoders and they use the same kind of encoders for the past 12 years, even in their latest product release FARO Edge arm.
ROMER has released their new Absolute Arm last year and this is the most reliable, accurate and stable arm available world wide in the market. ROMER is using the eoncoders from Leica and they are the most accurate and stable technology.
I strongly recommend to go for a ROMER Asbolute Arm...
Hope this helps...

Hello PitOh:

Thanks for your comment. We have already had a demo in house by Faro - I think we will schedule a demo with Romer. Thanks Much. :):cool:

1) I have been finding that Romer shows low reproducibility when I measure actual fixture pins and part features, located and clamped to same fixture. This affects the x,y,z feature location and is even worse
for IDs.
Are Romer arm probed points sensitive to probe "angle of attack" ?

FARO will be doing a demo in our plant on 2-16-2012. What type of set up did you have prior to the visit?

At the last company I worked for, we had intensive demo's of both types of arms. Three things that had Romer standing out for us was the durable encoder, the lower cost of annual calibration, and also the resistance to temperature change when taking measurements.

Calibration for the FARO arm requires the entire unit be packed up and shipped out for calibration at a hefty cost. With the Romer the calibration can be done in house on the equipment, which increases your up time and reduces your overall costs significantly.

As far as temperature, Faro's arm had to have a period of rest time to accommodate changes in temperature. Romer's did not due to the type of material the body is made from.

I left that company before they made a purchase, however the company I now work for has a FARO arm and has had to have the encoder replaced twice. If I had to choose at this point I would highly recommend the Romer.

Do you have a citation or source for this? We use the Faro system every day -our manual states that the FaroArm is permanently calibrated and only requires shipment for checks if physical damage or deformation occurs. The FaroArm will always require repair if it loses calibration and it will only lose calibration if it's damaged.

We've had ours for two years in a high production facility and have never had an issue.

William, I am going to have to look into it. That is the information we were given during the demo. Additionally that is the current practice being used where I work now.
