Geometric Dimensioning And Tolerancing GD&T

Geometric Dimensioning And Tolerancing GD&T

Duration (Days)



This course is designed for participants to learn the application of GD&T of the key concepts, drawing technic, analyse the measurement results and drawings in the GD&T system. Participants will learn all the symbols, rules, vocabulary, mathematical definition and standards in GD&T.

  • Learn the GD&T system and recognise the four major geometric characteristics.

  • Understand the symbols and abbreviations in GD&T

  • Learn the various type features control frames and the difference between composite and compound feature control frames

  • Apply GD&T to producer the parts with good quality and with high efficiency

  • Use maximum material condition to reduce risk and increase accuracy
