Repeating the curve measurement in a loop.

[[Ma...]]

Hello.

I have a problem. Namely, I measure curve 1 and then fit the circle to the contour. Sometimes it happens that it does not fit the circle to the curve and I have no result in the report. When I repeat the curve measurement, the circle fits and I have a report with all the results. I wonder if it is possible to do so in the program that if I do not have a result in the fitted circle, it will repeat the measurement of curve 1 in a loop. Maybe someone has an idea? I will add that I do not have the PCM option.

Regards.

Before setting up a formula to re-measure, you can try:

Maybe easiest... just open up your Recalled Points - Right click and "Add Range Limits"--- Then modify your range limits to allow data to be pulled from a larger area in the directions that are needed.

If that doesn't work, you could also try:
Set up a local alignment if possible and measure the Curve1 using the local alignment ---then open up your Recalled Points - Right click and "Add Range Limits"--- then select the Feature Alignment --- then set/verify your Box Limits

There is a possibility that curve is not being calculated after measurement. You can try to add alignment with curve in it to full run or mini-plan - just force it to calculate curve.

Awesome ideas. I love the "add range limits" option in Calypso. I think it's underutilized and probably buried a bit by the UI.

I have never experienced not calculated curve due to standard 5mm search distance.
But if there is instability of BA or parts are machined differently ( due part family for ex. ) then using alignment from curves is a good choice. But i use it especially for better accuracy - on active head it's doing dangerous moves if nominal point and actual position differs more than 1mm.

For adding range of points i often use special method for exact measurements. [list=1]

Make default curve

Make alignment from def. curve

Make duplicate of def. curve with it's alignment setted to CA from step2

Now you can make box selection where you can select it's boundaries relative to CA from step2
