3D Scanning and Model-Based Definition: A New Look at GD&T
The increasing quality and accessibility of 3D scanning tools, particularly computed tomography, are giving quality control experts much more information about the parts they look at, experts say.
Reverse Inspections of Orientation
I am trying to check the parallelism of the surface of a part in relation to Datum A. Is it acceptable to locate off of the surface of the part and indicate on the Datum A?
Composite Profile Control
Are the Datum structures in the two examples above valid for this drawing?If they are valid, wouldn’t both examples yield the same results when inspected?
Flatness - GD&T and Calypso Rev 3 Book
Flatness (form tolerance): the tolerance zone is limited by two parallel planes a distance t apart.
Implies: Straightness of the surface or Straightness of the derived median line
2-Day In-Person Public GD&T Training Event on July 9-10, 2024
This In-Person GD&T Fundamentals Public Training Course allows you to learn GD&T in 2-days - with a live in-person instructor, enabling you to complete training off site, without distractions from the office or home. In this course, we teach a simple framework for understanding how GD&T is used and why it improves the manufacturing process.
