Geometric Dimensioning & Tolerancing (GD&T) in Design through Manufacturing

Date : 13 to 15 December, 2021

Time : 1340 Hrs to 1700 Hrs


Understand the role of GD&T in reduction of manufacturing cost and lead time as well as enhanced product reliability. Thorough knowledge in GD&T – the essential link, connecting the functional departments in a manufacturing industry – is must for engineers. Many a times lack of proper understanding / misconceptions about GD&T lead to depriving the true benefits of GD&T in terms of enhanced reliability of the product, saving in manufacturing cost, reduction in lead time, etc. Learn the fundamentals of GD&T in detail with application examples.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organising a 3 days online training programme on "Geometric Dimensioning and Tolerancing (GD&T) in Design through Manufacturing".

Focus Areas

  • Tolerance, types of tolerances, why tolerance is required?
  • History, Introduction and understanding the need for GD & T
  • Fundamental rules of GD&T per ASME - Rule1 and Rule2
  • Coordinate vs Geometric tolerancing
  • Definitions of Terms and Symbols: Feature, FOS, FCF, MMC, LMC and RFS
  • DRF thro definition of datums and DOF restrained by primary, secondary and tertiary datums
  • Calculation of bonus tolerance per MMC / LMC - Learn through Exercises
  • Five groups of GD&T parameters - Form, Orientation, Location, Run out and Profile
  • Form tolerances and applications
    • Straightness
    • Flatness
    • Circularity
    • Cylindricity
  • Orientation tolerances and applications
    • Parallelism
    • Perpendicularity
    • Angularity
  • Location tolerances and applications
    • Position
    • Concentricity
    • Symmetry
  • Run out tolerances and applications
    • Circular run out
    • Total run out
  • Profile tolerances and applications
    • Profile of a line
    • Profile of a surface
  • Learn to Interpret above through Case Studies and Exercises
  • Inspection Methodology for GD&T Parameters

Key Take Aways
