Probe path

[daobs]

Hello everybody,
I have a program in my possession, which was programmed by a former colleague. In this program there is among other things an outside diameter, which is programmed as an Auto Feature. This diameter is measured with 6 measuring points.

Step 1: Between the measuring points 1-3 a circular movement takes place.

Step 2: After measuring point 3 (Z = -0.8) a movement in Z+ (approx. Z = +10) takes place first, so that the probe is positioned above the component. The probe then moves over the component and then positions itself before measuring point 4 at Z = -0.8 again.

Step 3: Between the measuring points 4-6 a circular movement takes place again.

As you can probably already guess, Z = -0.8 is entered as the target declaration for Z in the Auto Feature. But now I have to change this Z-value to Z = -1.3. If I adjust the value here, my complete probe path changes in such a way that the movement between measuring steps 3 and 4 is deleted and a collision would occur.

Now my question: Do you know how I can adjust the path between these two measuring points again so that I avoid a collision? By clicking on the probe path in the display window I can only move the probe points, but not the probe path and certainly not in Z.

I have attached a screenshot from the preview image of the unchanged Auto Feature. I hope I have translated all terms of the PC-DMIS software correctly, because I use the German version.

After you adjust your Z depth, you will need to view the contact parameters. Place the cursor at the 'hit' prior to the 'move' where you want to insert. Then select 'insert'\'move'\ move point. This will insert the move command. then adjust the move parameters.

Side note..

PLEASE consider taking the "." out of the name of that feature.

Names of things in PC DMIS should ONLY have numbers, letters, or underscores. NO OTHER SPECIAL CHARACTERS. This will save you a lot of problems in the long run.

Is there something " close " tot the outside of the Stud you are measuring ? Is there an actual reason to jump from 1 side or the other ? If not, change the number of hits in the feature and it will re-generate your path. You could also consider a larger PREHIT / RETRACT distance to accomplish a similar task as well.
