Anyone know how to use a white light sensor??

Sleepmode
Hi all,
I'm pretty new at PCDMIS and am scheduled for training on the white light sensor in July but I have a request to perform a scan on a piece of lead. I need to scan a ~1mm x 1mm square and report the results (hopefully a color, 3d rendered graphic). I think the engineer is primarliy looking for surface roughness. We are attempting to compare results from an outside measurement house. The range from the outside vendor looks to be about 30 microns (peak to trough). I am not sure of the resolution of this sensor and if we are even capable of accurately performing the measurement. I would hope this thing can measure down to a micron or two.

I couldn't get the linear open scan to work so I created a pattern (offset a surface point by .04mm) and pasted that pattern in the machine Y. So now I have 1 line made of 26 points. The scan worked fine. Then I tried to creat a report but couldn't find a way to get it.
My end goal was to offset the 26 point line by .04mm in the machine X to complete my 1mm x1mm square.

Thanks in advance
  • It’s a shame that no one has responded to this post in 5 ½ months. Our Optiv 664 is in the process of being installed right now. It has a 3mm chromatic white light sensor that I have not yet been training for. I had training for PC-DMIS Vision two months ago but they didn’t have a CWS available to even look at.
    The technician setting up the Optiv 664 told me he has seen about 50 optical CMM’s with the CWS but only about two or three of them were ever used. They cost more than a laser, so how can people buy them and not use them?
  • We have the 660um, 3mm and 10mm CWS sensors. I have been teaching myself to use them and have come to rely on them quite heavily for surface measurements. Previously, I had been using a laser on a different machine for many years.

    The CWS and PC-DMIS gives me much more power to be specific and get exactly the data that I want. At the same time, PC-DMIS requires that you be VERY specific. I have had to develop an entirely new personal tool box of programming tricks to get exactly the scans that I want. That said, I know there is more that the CWS can do and I am not getting its full potential yet.

    Part of the difficulty is that the company which develops the CWS keeps everything in house. You see that most things are processed via the CHRocodile box and that only passes some data back to PC-DMIS. This is why many of the features that are available to the Laser in PC-DMIS are not available to the CWS. It also seems to by why the CWS can be very picky about how it operates. Once the box errors out, it can be difficult to recover without a restart.
  • I know how. Drop me an email if your problems persist. I can't train you over the phone, but I can point you in the right directions until your training is actually conducted.
