Probing an angle in Z to find the intersection

[Mic6]

Is this possible? I have my part setup on an angle plate, so as the 45 deg angle is now parallel in Y. Is there a cycle I can use to probe the angle and the flat to find the intersection? Or any other ideas?

[John Summers]

There's no image.

If you are useing Renishaw, I would try

9815/9816, Internal/External corner.

Renishaw states the the intersection can be found even it the corner is not 90 degrees.

Can you probe center position between the angle you have dimensions on and the other angle at the left side of the image? Just like finding the midpoint of two edges, if the angles are the same and since the probe is a ball it should find the center accurately providing your angles are accurate.

[Mic6]

That's a hell of an idea Matthew. I have to get back to that job at the end of the week. Thanks, I'll give it a shot.

Mic6,

 

I thought I would share the solution with the community.
