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

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

Date : 22 to 23 April, 2024   Location / Mode : Pune


Understand the role of GD&T in the reduction of manufacturing cost and lead time as well as enhanced product reliability. Thorough knowledge of GD&T – the essential link, connecting the functional departments in the manufacturing industry – is a must for engineers. Many 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 organizing a 2 days offline training programme on "Geometric Dimensioning and Tolerancing (GD&T) in Design through Manufacturing".

  • 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

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

  • Understand the concepts of GD&T features and correctly interpret GD&T symbols in Engineering Drawings
  • Learn about using Geometric tolerances at RFS, MMC and LMC conditions and Calculate Bonus tolerance
  • Learn Interpretation of GD&T Parameters
  • Learn GD&T through Case Studies and Exercises
  • Gain an insight into inspection of GD&T features using conventional methods

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 program will be conducted by Mr. Yuvaraj Patil.

Mr. Yuvaraj Patil is a mechanical engineer having more than 16 years of experience in CNC Machine Shop & Tool Room. He has worked with various companies – ASB International, Videocon, Menon & Menon and PARI. Additionally, he has 9+ years of experience in training engineers in CNC Machining area with hands-on practice.

He has trained 2000+ Industry professionals in the CNC Machining area, Dimensional Metrology, and Inspection. And trained 400+ fresh graduate mechanical engineers in Production engineering for making engineers industry ready.

Also, he has conducted the training program on Machining fundamentals, Dimensional Metrology, and GD & T for Sigma Electrical, Maruti Suzuki, Volkswagen, Mahindra and ENPRO.


Prior registration for participation is necessary. Number of participants is limited and will be accepted on ‘First Come First Serve’ basis. A Certificate of participation will be issued to participants.
