IMTMA Training Centre

Advanced Concepts of GD&T

Date : 22 to 24 February, 2021

Time : 1400 Hrs to 1700 Hrs


In today’s scenario, Design, Manufacturing and Inspection personnel working on engineering parts and assemblies are required to be familiar with the basics of GD&T. In addition, there is a need for engineers to have knowledge of advanced concepts provided in ASME standards which results in realizing the benefits of GD&T - interchangeability, reduction of manufacturing and Inspection costs, elimination of rework etc.

Keeping this in view, IMTMA is organizing an online training on 'Advanced concepts of GD&T'

Focus Areas

  • Datums- Constraints, RMB, MMB, LMB, Moving datum targets, Datum translation, customised Datum Reference Frame
  • MMC, LMC, RFS applications
  • Virtual condition, Resultant condition, Bonus and Datum shift
  • Functional gauge design
  • Fixed and Floating fastener conditions
  • Zero positional Tolerancing, Separate and simultaneous requirements, Projected Tolerance Zone
  • Composite Position and Profile Tolerancing
  • Inspection methods of geometric controls
  • Coaxiality options
  • Discussion of datum strategy and GD&T controls for sample assemblies

Key Take Aways

After attending this programme, the participants will be able to:

  • Select optimal datums and material modifiers while creating design drawings
  • Tolerance Analysis, correct interpretation of drawings
  • Understand the GD&T hierarchy and optimise tolerances to gain manufacturing and inspection cost benefits
