SmartGD&T for Design, Manufacturing + Inspection

Goals 

To provide participants with a fundamental understanding of: 

  1. The purpose and essence of GD&T 

  2. The perfect imaginary world of GD&T 

  3. The imperfect real world of machine parts and their features 

  4. The things which can go wrong with machine part features: Form, Size, Orientation and Location 

  5. The GD&T tool kit provided by the ASME Y14.5M 1994 & 2009 standards 

  6. The functions of Nominal, Basic and Reference dimensions 

  7. Cartesian coordinate systems, Degrees of Freedom and the Right Thumb Rule 

  8. The Envelope Rule, the Free State Rule, the Rule of Simultaneous Requirements, the Rule of Composite Feature Control Frames, the Rules of Datum Feature Simulator Management, and the Rules of Natural Datum Reference Frame establishment. 

  9. The capabilities and applications of the most important Geometry Control Tools (Surface Profile, Position, Perpendicularity, Diameter, Width, Dimension Origin. Flatness) 

  10. The Feature Control Frame reading and “decoding” processes 

  11. The Datum Reference Frame establishment process 

  12. “Material Condition” concepts and modifiers, including the tolerance zone size and tolerance zone mobility modifiers (S), (M) and (L), and their effects 

Duration & Presentation Options:

This course is normally delivered in three consecutive classroom days, and two consecutive application days. Depending on the number of participants and travel logistics, the classroom and practical sessions may also be delivered in half day segments. 

Who Should Attend 

All persons with significant responsibilities for Product Design, Drafting, Tool Design, Machining, Manufacturing, Manufacturing Management, Manufacturing Process Control, Inspection, Gage Design, Coordinate Metrology, Robotic and manual Assembly, even including team members with significant experience, in order to refresh their knowledge and discover new and important fundamental concepts. Management is also encouraged to include several members of the internal GD&T Advisor team, in order to encourage them to test their skills leading exercises and discussions.

Prerequisites 

Participation in the course “Beginning SmartGD&T”, and working familiarity with GD&T, “blue prints”, and manufacturing, metrology and assembly processes. 

Preparation 

Participants are encouraged to come armed with lists of questions on topics which have created design, manufacturing, inspection or assembly difficulties in their experience. In case the course customization option is ordered, each participant is encouraged to submit at least one drawing which represents some of her or his current GD&T concerns. These should be collected and reviewed by the in-house course coordinator and made available to the instructor well in advance for preparation. Participants are encouraged to bring pencils with erasers (not pens), and pads to class.
