Applying GD&T in Design through Manufacturing – Practical Workshop on What, Why and How?

Date : 27 to 29 June 2022

@ IMTMA Technology Centre, Bengaluru

Introduction

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. The application of the GD&T system helps to reduce manufacturing and inspection costs drastically.

Many times, having GD&T symbols are understood, doubts prevail about the selection of datum and applying the right parameters during the design process. Selection of the right DRF, as well as GD&T parameters meeting the functionality and manufacturability requirements, is the key to successful design for higher reliability and at a low manufacturing cost.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organising a 3-day workshop on "Applying GD&T in Design through Manufacturing – What, Why and How?” with a practical approach par industry. All participants will be involved in three projects with a detailed study of design intent, selection of datum, and applying GD&T parameters for the various parts of the assembly based on the functional perspective.

Focus Areas



 Recap of Definitions, Terms, and Symbols of GD&T as per standard

  • Tolerance concepts, MMC / LMC / RFS and their applications
  • Calculation of bonus tolerance per MMC / LMC
  • Definition of datums and Datum reference frame (DRF)
  • Fundamental rules of GD&T per ASME
  • GD&T Form, Orientation Location, run out, and profile tolerances in brief

Advanced concepts in GD&T

  • Virtual Condition
  • Worst case boundary
  • Datum shift
  • Composite Position tolerance
  • GD&T Parameter selection criteria

 Case studies

  • Study of design intent
  • Selection of DRF
  • Applying the right GD&T parameters
  • Validation of GD&T parameters

Practical workshops

  • Workshop 1 – Machine tool spindle design
  • Workshop 2 – XY Table design

 Practical workshops

  • Workshop 3 – Industrial Gearbox design
  • Interaction and review of all 3 workshops

 

Unique Feature of the Programme

  • Workouts in groups, Presentation and Review
  • Practical workshops for GD&T application
  • Understanding the product function before GD&T
  • Why and How GD&T from performance perception
  • Negative impact of inappropriate GD&T on cost and performance
  • Debate on why-why of GD&T during application
  • Debate on design optimization from GD&T perspective

Key Take Aways



  • Understand the concepts of GD&T features and correctly interpret GD&T symbols in Engineering Drawings
  • Learn about using tolerances at RFS, MMC and LMC conditions and Calculate Bonus tolerance.
  • Gain a practical insight into inspection of GD&T features using conventional methods
  • Learn how to select right GD&T parameters
  • Learn a selection of GD&T parameters through many workouts using actual assembly and part drawings
  • Learn through group activity on GD&T parameters selection
