CMM vision error in manual mode

I keep getting the error: "Hit target is out of detection range for feature ___"

This is when I am in manual mode and trying to take a hit using an auto feature. I don't get this error when I first create the auto feature (say an edge point). What I am trying to do is manually set up a coordinate system for the rest of the program to go off of.

The issue comes when I go to measure the second part after creating the program based off of the first part. I am only able to position the new part to within 100s of micrometers and I then get this error message. If I take a bunch of time and get the second part pretty close to lined up (less than 10 micrometers) to where the first part was then I don't get this error message. The only work around that I have found so far is to recreate all of my manual hits each time I measure a new part. This seems extremely inefficient and I feel that there must be a better way to do this or a way around this error message.

Thank you for any suggestions!
  • In manual mode the CMM will not move to the location of the next point. The auto feature is already looking for the feature that’s not there. Either use manual feature with manual mode or use DCC to go to the next alignment point. If the parts are reliably consistent you might have success with an auto feature. If not, use a manual hit target until your alignment is complete.
  • rickfngp,

    I am using the CMM in manual mode and moving the machine to where I want it to take each hit. For a surface point it shows the target on the screen and I just move it over the part. Then it tells me to press continue whenever it is aligned.

    With Vision there doesn't seem to be any features that I can use other than Auto Features and Constructed Features, please tell me if I'm missing something! I know to use Measured Features when I'm using styli and I never have a problem with those. Only with Vision features.
  • I'm not at the cmm, but in the feature window, there's a icon that you canselect, it allows a manual position, whatever was the first one (manual pre position ?)

    In PC-DMIS Vision 2013 there's only toolbars for Auto Features and Constructed Features. In 2014.1 there's a toolbar for Measured Features but I've only seen it as all grey. I just started using 2014.1 today. I've never used a surface point in Vision, only edge points.

    If you could describe what this icon looks like it would be extremely helpful! I'm currently making sure that I am in Manual Mode(Alt+X) - looks like a joystick - but that's the only icon that I'm checking.
  • I think it's in auto feature, a little blue head. You can use auto features as a manual mode with this, I do it usually for optical measurements.

    Are you talking about the button labeled "Manual Pre-Position Toggle"? On my vision auto features this is greyed out if I'm in manual mode (joystick) but is highlighted in DCC mode (arrow). Should I be making my initial alignment using DCC mode with the "Manual Pre-Position Toggle" on? Is this the standard procedure?

    Thank you for the feedback!
  • So I tried using the "Manual Pre-Position Toggle" in combination with DCC mode. This DCCs me to the nominal location of the hit and then asks me to line up the hit manually. This is great for parts where I'm positioning the part fairly close! Thank you!


    What would you recommend if I have two parts that I am measuring at the same time separated by a long distance? (My CMM is very slow - less than 10mm/s!) If I use this method then I have to travel manually from the first part to the second part for every single hit which can take quite a while. Is there a better method for this situation? Thanks!
