Geometric Dimensioning and Tolerancing(GD&T)

Objectives:

  • Properly interpret manufacturing drawings
  • Identify the needs for GD&T, considering Assembly, Manufacturing and Functionality
  • Apply suitable tolerances to mating parts and features
  • Apply GD&T symbols on Manufacturing drawings, per ASME 14.5-2009
  • Understand the allowable variation in finished part sizes
  • Illustrate the inspection methods required to check part suitability

Agenda:

  • Tolerance, why tolerance is required and how it is decided
  • Types of tolerances, conventional and un conventional (GD&T)
  • History, Introduction and understanding the need for GD & T
  • Advantages of GD & T over conventional limit tolerancing
  • Fundamental rules of GD&T
  • Co-ordinate vs geometric tolerancing
  • Feature definitions, size feature and surface feature
  • Definition of material/feature and datum modifiers, RFS,MMC,LMC
  • Definition  of  datums and DOF restrained by primary, secondary and tertiary datums
  • Selection of datums based on Design intent / Assembly /   Functionality
  • Form tolerance and their application
  • Tolerance concepts, MMC / LMC / RFS and their applications
  • Calculation of bonus tolerance per MMC / LMC
  • Position tolerances and application
  • Run out tolerances and application
  • Profile tolerances and application
  • Practical application of GD&T on assembly parts
  • Final tests on proficiency and application of GD & T
