Geometric Dimensioning & Tolerancing

The BEC is offering a two-day session in GD&T. Participants learn to develop, understand and apply this widely accepted language of design. Emphasis is on practical application, datum reference frames, various tolerance types, characteristics, symbols and the latest ASME standards. This session is designed for supervisors, technicians, engineers and operators involved in product design, manufacturing, process design, quality planning and quoting. Participants are encouraged to bring drawings, photos, samples, or other types of examples for questions and class discussions.

Course content:

• Symbols and terms
• The Geometric System – How it Works
• Position Tolerance Verification
• Limits of Size
• Datum Reference Frame – Theory, Selection, Qualification, Applications – Datum Modifiers
• Tolerances – Form, Orientation, Profile,
• Position Tolerances – Cylindrical, Rectangular, Spherical, Conical
• Coaxial and Non-Cylindrical Controls – Runout, Concentricity, Position, Profile and Symmetry
• Fastener Formulas and Screw Threads
• IB and OB Stack-up Calculations

Upon completion, you will be able to:

• Assist manufacturing in producing parts faster with less cost
• Enhance communications with customers and suppliers
• Minimize rejects, reduce rework and scrap
• Properly apply GD&T to your drawings and examples
• Improve competitiveness by increasing productivity, lowering costs, maintaining quality and ensuring reliability
• Understand GD&T symbols, terms, characteristics and use the Datum Reference Frame
