To modify a feature command in your measurement routine, follow these steps:
Place your cursor on the feature that you want to edit in the Edit window, and press F9 to access its Auto Feature dialog box.
If you have a DCC machine and have already established and ran your "first alignment" with a real part, you can click the Move To button in the Auto Feature dialog box to move the Field of View (FOV) to the center of the feature. This button works only on DCC-enabled machines.
If you have not established the "first alignment" for your measurement routine, do not click the Move To button. Doing so may cause the stage to run off or damage the part you are measuring. Remember that PC-DMIS first needs to know the location of the part on the stage (its orientation and level) to calculate the target feature location. See "Creating an Alignment".
Switch to the Vision tab in the Graphic Display window.
Ensure that the lamps are properly illuminating the edges of the feature. If you need to make changes, switch to the Illumination tab on the Probe Toolbox and make the necessary adjustments.
Click the Test button in the Auto Feature dialog box. PC-DMIS Vision inserts a temporary test feature into the Edit window and executes the feature.
Examine the detected points in the Vision tab. These points indicate the raw hits PC-DMIS uses to fit the geometry. If there are outliers that you want to reject, use the Hit Targets tab on the Probe Toolbox, and make changes to the Filter Parameter Set. If the detected points are not at the location you expect, continue to the next step.
Access the Preview window (View | Other Windows | Preview) to ensure that the feature was properly measured in this test.
If the test data appears to be incorrect, these suggestions may help to fix the problem:
If most of the feature appears to be correct but one region is returning incorrect points, insert a new target in that region. Set different parameters (such as illumination, edge detection, and filters) until that region of the feature also measures correctly.
Click the Hit Targets tab of the Probe Toolbox and insert a new target in the target region. See "Probe Toolbox: Hit Targets tab".
Click the Hit Targets tab of the Probe Toolbox and adjust the target parameters. See "Probe Toolbox: Hit Targets tab".
Click the Illumination tab of the Probe Toolbox and adjust any illumination settings. See "Machine Options: Illumination tab". The software applies the changed illumination settings to any targets currently selected in the Hit Targets tab. You may also use the attached pendant to set the luminosity if the machine supports it.
Once you have made the suggested changes, test the results of the target by clicking the Test button again. When you are satisfied with the target results, continue with the next step.
Make adjustments to the options on the dialog box as needed.
Click the OK button on the Auto Feature dialog box to update the feature with the new settings.
The Auto Feature dialog box shown above is the expanded version of this dialog box. Click the << button to see the reduced version of the dialog box.
Modifying a feature command in an offline measurement routine is very similar to modifying an online measurement routine. The only difference is that in Offline mode, you don’t have an external pendant. Dragging with the right mouse button in the CAD tab simulates the stage motion.
