How to report TP correctly?

[dfiola66]

Attached pic shows the part in question. The surface the hex hole is in isn't normal to any axis (hole is in tab bottom left pointing down). When reporting TP for this hole, it should be reported in 2 axis's only as the third is form location, not hole location.

What is the correct way to do this? I've constructed a plane of points off the tab. How do I report the TP of the hex normal to the tab surface and not in car position as it includes form variation?

Thanks for the help.

2D True Position

When you output the true position dimension select the option perpendicular to centerline and include all axis in the dimension. This option will calculate the 2D true position based on the normal vector.

You da man! Thanks for the help. I never have used that option prior. It will be very useful in the future. On my old manual cmm, I'd measure the plane first, set the plane as my working plane, and then measure the hole. The resulting deviations would be 2d normal to the plane.

I knew that process had to be possible in dmis but until now, wasn't figuring it out.

2D True Position

That option wasn't added until version 3.5 came. Which is absolutely rediculas. Before we purchased the upgrade, I had to come up with a way to calculate the 2D true position. That took quite a while to figure out how to do it.

What where you running a Mora?

What where you running a Mora?

was and am running 3.5mr2 (loaded 3.7mr3 but it's not working currently..still need to create a program, make it fail, and email the log, program, data to tech support so they can try and figure out whats up...haven't had the time).

anyhow...didn't even know the option existed!

where in Detroit are you Paul? I lived in the city proper for 5 years (near Harper Woods/St. Clair shores 7 mile area), high school in Warren (10 and Hoover area), and have friends and family all over the area (sterling heights etc)
