IMTMA Training Centre

Advanced concepts of GD&T

Date : 26 to 27 Jun, 2018

@ Pune

Last date for registration 19 June 2018


The Geometric Dimensioning and Tolerancing systems have been getting evolved over the last 20 plus years continuously. Globalization in various streams of engineering has been instrumental in defining the details and implementation . ASME has revised and improvised the definitions in the last release of year 2009 with examples in which almost all the readers find their own parallels.

However, thorough understanding is a must across the design, manufacturing and quality personnel for implementing GD&T and realizing the true benefits in terms of interchangeability, reduced cost, reduced re work, simplified inspection & gauging etc. Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing a 2 days programme on Advanced concepts of GD&T on 26 - 27 June 2018 at Pune.

The program will be focusing on application and interpretation of GD&T interlaced with interesting real life examples which the participants from various industries will be able to identify with. Participants can seek solutions from the expert faculty for discussing and solving their specific issues in design / product development.

  • Definitions of Terms and Symbols, MMB,LMB,RMB,DRF, Rule#1 or Taylor principle
  • Definition of datums’, Selection of datums based on design / manufacturing / Inspection requirements.
  • Wooden/plastic prototypes: Part/assy prototypes used for effective training.
  • Brief explanation five groups of tolerances and their hierarchy
  • MMB,LMB, RMB and translation concepts
  • Zero tolerance and application (straightness - axis, orientation and position)
  • Virtual conditions, IB and OB calculations and applications
  • Paper gauge concept, and Verification of positional tolerances
  • Functional dimensioning and Functional gauge design
  • Composite position and profile tolerances, PLTZF and FRTZF
  • Floating and fixed fastener assy
  • Axis controls by position, run out, concentricity and profile, case studies
  • Verification of effect of datum modifiers / datum shift - using paper gauge
  • Exercises throughout the work shop, over 25 nos
  • Live Demo of Measuring GD&T parameters
Key Take Aways

After undergoing the GD&T workshop, the participants would be able to :

  1. Distinguish between RFS, MMC and LMC conditions with practical applications
  2. Do position verification: By calculation, paper gauge, functional gauge and CMM.
  3. Apply new concepts, MMB,LMB,RMB and translation, and functional gauge design
  4. Understand advanced concepts viz. Zero, composite position and profile tolerancing
  5. Selection of axial controls position, run out, profile and concentricity, case studies
  6. Gain a practical insight into inspection of GD&T features using conventional methods, co-ordinate Measuring Machine.

Participant Profile

This programme will benefit Middle/ Senior management members from functions of Product Design, Process Planning, Production, and Quality Assurance from Machine Tool, Automobile & auto ancillaries, Tool Rooms, Consumer Durables, Aerospace, Defence & Railway establishments, General Engineering industries and Engineering service providers.

Pre requisite: This will be an advanced level training programme. Basic Knowledge of Engineering Drawing, Limits/Fits/Tolerances and GD&T principles will be a pre requisite for this programme. Participants need to complete a precourse questionnaire upon applying for registration.

Participants are encouraged to bring their drawings / designs for discussion and problem solving.


This programme will be conducted by Mr. Srinivas B, Industry expert in Product design and development. Mr. Srinivas has more than 23 years of rich experience in Aerospace and Auto industries in leadership roles within India and international locations. He is GDTP Senior professional, certified by ASME. Had worked on several re-engineering projects in both product and tool design areas, which resulted in lower weights & costs, ease of manufacturing & assembly while maintaining design intent intact. He has thorough knowledge of various Quality Standards for enhancing the operational efficiency such as Six Sigma, ISO9001, TS16949, etc.., and is a Six Sigma green belt trained and certified by Cummins.
