Groove width and position

[[Da...]]

Hello Guys.

Which method would be the best for check this groove width and distance?
0.88 - 0.93
9.47 - 9.53

See picture

A magic wand?

Maybe I'm not interpreting correctly, but that looks like an undercut groove on an ID. Those are always fun to measure, particularly where the id is too small to fit your normal star system into. In such cases, we usually end up building a custom t-probe system, with the stylus shanks cut short and pressed into the main shank.

Also, my calibrated eye may not be reading the picture correctly, but it looks like the sidewalls of that groove are only about .2 mm. That's going to limit the diameter styli you can use just a bit.

I would try Construction/Step Point. Set the Step angle to 90 and select Result two. It will report the point along a 2D line where the form changes abruptly. Use as styli with as large a diameter as possible.

Is it any gauge etc. that I can use for position check ? 9.53 ?

Wow! All this time I had no idea something like that was available. Is there any information available about the accuracy limitations?

This is new to me, also. I will be using this today and making an accuracy comparison with existing program and floor gauges.

The accuracy of this function is pretty decent. That opinion is based on the small amount of testing I was able to do with it 5 or more years ago so take that with a grain of salt. Using a 2D Line scan at reasonable speed, with a styli large enough not to get "caught" by the form change and you should get repeatable results.
