Scanning interrupted circles.Advice please!

Hey folks. I need some advice. I want to scan the diameter of a bladed disk to get the Diameter and form. How do I go about scanning an interrupted surface like that? Is it possible to create a circular scan or do I need to do a bunch of small scans and extract the extreme point of each the construct a circle from that?

You can use a basic scan circle on a little angle, then copy/paste with pattern.
Maybe you can also perform a linear closed scan, and then construct a mincirc circle.

Thanks jefman! What do you mean by little angle? A small arc comes to mind am I following you correctly?

I would assume Linear Closed scan with 'Jump holes' might be a better option to get it all in one scan. Then construct the diameter from that.

Ah that's a great idea! It will run quicker and much smoother like that! Thanks badger!

Badger can this be done without a CAD model? It doesn't seem to be working. I can't get it to generate anything

Ah, no, it's uses the CAD selected surfaces to generate the path!

Make a circle scan with the desired angle ( for example start 0 end 15 degree) Make a loop and then make a construced circle of the small scans you can do the same with linear open scans. !! Important, make sure your workplane is set correctly or Pc-DMIS will trick you If you dont prefer loop "insert with pattern" option is works well too, i just like my programs nice clean and tidy and short as possible so i do loops. Hope this helps

I experimented with that today. Only problem is that wherever you tell the probe to start, if it doesn't hit a surface it won't begin the circular motion. The reason it's so tough is because the vane tips are not equally Spaced and there's 107 of them! Here's a picture for example
