Tolerance Stack-Up Analysis
Date : 23 to 25 May, 2018
BIEC, 10th Mile Tumkur Road, Madavara Post
  • Understanding of stacks and why do we need it
  • Statistical tolerancing, Process capability indices and 6 Sigma
  • Loop diagram and the dimensional objective or critical functional relationship to analyze.
  • Calculate nominal output and statistical variation using statistical methods.
  • Worst case tolerance calculation, WC
  • Effect of dimensioning practices on tolerance variation
  • Root Sum Square, RSS and Modified Root Sum Square, MRSS
  • Empirical correction factors, Bender, Gilson, Gladman, and Greenwood.
  • Geometric Dimensioning & Tolerancing, application in Stacks analysis
  • Part stacks using bonus tolerance and datum shift, Float and biased floats
  • Effect of form and orientation tolerances in Stacks
  • Assembly stacks using profile, run out and position

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

  • Understand stack-up analysis and why it is required in today's design.
  • Analyse and optimize the designs for ease of manufacturing and assembly while keeping functionality intact.
  • Identify the critical tolerances which require tighter tolerance control or statistical process control, SPC.
  • Enlarge drawing tolerances and thereby reducing cost of design.
  • Develop robust design with low risk of failure.

    Participant Profile

    This programme will be an advanced level one and will benefit Designers / product design engineers responsible for specifying, interpreting and analyzing tolerances.

    Knowledge of Engineering Drawing and GD&T principles will be a pre requisite for participants to learn the techniques of tolerance stack-up analysis.


    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 has immense hands on experience on stack-up analysis and carried out several complicated projects involving 20 to 30 components and several  floats. 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.
