Geometric Dimensioning & Tolerancing



Geometric dimensioning and tolerancing (GDT) is a drawing language used for communicating part requirements on engineering drawings. To ensure the final product meets the original engineering blueprint, specifications, everyone who makes or reads engineering drawings should be using the same method to communicate. Using GD&T reduces interpretation errors, and increases manufacturing tolerance and quality throughout the engineering and manufacturing process.

This three-day course is for engineers, quality assurance and manufacturing personnel who must understand and apply GD&T in order to design, manufacture, or inspect a product. This course emphasizes the reading of engineering drawings prepared in accordance with the ASME Y14.5M-1994 standard.

Program Contents:

  • Fundamentals of Geometric Dimensioning and Tolerancing including all 14 geometric characteristic symbols.
  • Typical application of symbols; proper interpretation and common inspection techniques.
  • Basic and Unique Applications of True Position and Extended Datum Principles.
  • Effects of RFS (regardless of feature size) and MMC (maximum material conditions).
  • Use of fixed (bard) gages to verify geometric requirements.

Program Benefits:

  • Learn to define part function through latest ASME Y14.5M/ISO standards.
  • Save time and money through clearer and consistent communication throughout the entire production cycle.
  • Be able to apply geometric dimensioning and tolerancing in your job.

Who Should Attend:

  • Quality Managers and Engineers
  • Individuals performing or preparing to perform hands-on bench work for geometric dimensioning

Program Duration:
