Profile question

Hello,

What would be the correct way to enter this into a profile characteristic? I am programming on an offline seat CALYPSO 2017 Version 6.4 (28.06.2017) that will be ran on CALYPSO 2020 Version 7.0.2003 (13.6.2023) Thank you!

Keep in mind this is a UZ tolerance which offsets the nominals. You can either manually offset the nominal, so that you can just use a straight up normal bilateral tolerance, or if you want to use the bilateral unequal distribution settings, I believe it should be set with a tolerance of 5, and a tolerance (one side) to 2. I hope someone double checks my math. 🙂

Here's an example i use all the time to remember the "conversion" from DIN to ASME

Ok. Maybe I'm a little slow, but how do you go from a drawing tolerance of 5 / -0.5 to a Calypso setting of 5 / 2.

I'm just looking at the math and it doesn't make any sense to me. Where did the 2 come from?

The ASME version, which is what Calypso is asking, is how much of the tolerance is outside of the material. The UZ in ISO is not the same thing it is an offset of the nominal location. 

The math is this though, a standard Profile of 5mm would mean that you have ±2.5mm or (2.5mm on the outside, and 2.5mm on the inside). A Profile of 5mm with a UZ of -0.5mm would now mean that you would have a tolerance of -3/+2 because it was offset 0.5mm inside of the material. The Calypso setting (by default) is asking for the base tolerance (in this case 5mm), and now only 2mm worth of the tolerance is allowed on the outside of the material. 

If you were to have made this for ASME it would look like this:
