"Bogus" Datum Reference Frames (Summer 2024)

Описание к видео "Bogus" Datum Reference Frames (Summer 2024)

The GD&T Guy explores a mistake he sees on many drawings: the recycling of datum references resulting in "bogus" callouts that don't reflect part function, and cause trouble for inspection.

All of the drawings referenced in this and the other episodes in the series can be found at https://mountaintopdevice.com/gdt-guy... - all free for you to download, use, and share!
