Y axis wrong coordinate.

[marfrez]

Hello, while drilling I am getting wrong y-axis coordinates.

All y-axis coordinates should be the same "Y-67." or "Y67."

Do you have any idea what I'm doing wrong?

I am sharing a link to this project below.

Hi

There are no setups  and toolpaths in the linked file, it will be difficult to determine the problem without these as we don't know what selections you have made in your setup and toolpaths.

Rather than share a link, its better to GOTO File>Export>Save as .f3d/.f3z and attach the file to a reply here.

What sort of machine is this on, from the code it appears to be a Haas mill of some sort?

[marfrez]

Thank you.

I add a file.

[marfrez]

Post processor should be good, wrong coordinates are in simulation so as in code for machine.

Hi

The problem is to do with the Model Box point selection, please see video for more explanation

[a.laasW8M6T · Accepted solution]

You can see by drawing a rectangle around the model and making it coincident with the edges that in one dimension its is off by 0.018 which explains the 0.009 offset

[a.laasW8M6T · Accepted solution]

Further investigation reveals this error is due to the distance between these wo faces being 58.1mm vs 58mm for the other 3 similar cutouts

This is why I think its important not To use Model box point when machining Cylindrical parts with cutouts or other features on them and instead to explicitly select a known centralized edge or point for the WCS origin

[marfrez]

Thank you very much for your help and for your time. 

This solves my problem in its entirety. 

Interestingly, I didn’t know how to measure relative to WCS or Component origin.

I always use a keyboard shortcut to measure something, and in the program window, I don’t have that option, but when I click on the icon, I already have that option     

I didn’t expect that the function triggered by a shortcut would work differently than when clicked.

[a.laasW8M6T]

Yes

they are actually two different measuring tools, I brought it up when the new one was released that the "I" key doesn't bring it up in Manufacture it uses the Design measure tool, but it really got nowhere with Autodesk.

you are right though its not very discoverable, I might bring it up again

[marfrez]

If it weren’t for that broken part and your help, I would have never used this icon.
