IMTMA Training Centre

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

Date : 18 to 20 December, 2018

@ BIEC, 10th Mile, Tumkur Road, Madavara Post, Bangalore


Geometric Dimensioning and Tolerancing (GD&T) system eliminates ambiguities in engineering drawings and brings out the designer's intent very clearly. It ensures seamless communication between design, engineering, manufacturing and quality teams across the entire organization enabling them to work in a concurrent engineering environment. Application of GD&T system helps to reduce the manufacturing and inspection costs drastically.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organising a 3 day training programme on Geometric Dimensioning and Tolerancing (GD&T) in Design through Manufacturing on 18 - 20 December at Bangalore. This programme will focus on understanding the system of GD&T and the methods of applying it in real time designs and will be supported by examples, practical demonstrations on CMM and exercises.

Focus Areas

  • Tolerance, types of tolerances, why tolerance is required, and how tolerance is decided
  • History, Introduction and understanding the need for GD & T.
  • Fundamental rules of GD&T per ASME. Coordinate VS geometric tolerancing.
  • Definitions of Terms and Symbols, FOS,FCF,DRF, Rule#1 or Taylor principle
  • Definition of datums' and DOF restrained by primary, secondary and tertiary datums
  • Selection of datums based on design / manufacturing / Inspection requirements.
  • Wooden/plastic prototypes: Part/assy prototypes used for effective training.
  • Form and orientation tolerances and applications
  • Location, runout and profile tolerances and applications
  • Tolerance concepts, MMC / LMC / RFS and their applications
  • Calculation of bonus tolerance per MMC / LMC
  • Inspection methods and Animations for form tolerances and important concepts
  • Exercises throughout the work shop, over 35 nos
  • Demonstration of GD & T measurements using CMM

Key Take Aways

After undergoing the programme, the participants will be able to -

  1. Understand the concepts of GD&T features and correctly interpret GD&T symbols in Engineering Drawings
  2. Learn about using tolerances at RFS, MMC and LMC conditions and Calculate Bonus tolerance.
  3. Gain a practical insight into inspection of GD&T features using conventional methods, Co-ordinate Measuring Machine and functional gauges.
  4. Implement GD&T controls for a new project with proper selection of datum features.

Participant Profile

This programme will be a Mid Level one and participants are expected to have knowledge of Engineering Drawing as a pre requisite.

This programme will benefit Managers, Engineers and Supervisory Personnel involved in the 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 and other Capital goods manufacturing industries.

Participants are encouraged to bring their drawings 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.
