Description

Mechanical designs can be complex involving numerous parts and sub-assemblies. In the manufacture of these parts and sub-assemblies, they are subjected to variation. Hence, a better understanding of their form, fit and function is vital. For better clarity and quality acceptance, more firms are now specifying their engineering drawings using GD&T symbols so as to better control its geometric and functional characteristics. Tolerance stackup methods are then used to ensure that the cumulative effects of these tolerances are acceptable to the functional aspects in a sub-assembly. In this course, a disciplined tolerance stackup and analysis approach would be applied on engineering part assemblies subject to different and multiple GD&T specifications.

Objectives

  1. To be able to identify, determine and ascertain the degree and variation of fit about a particular design assembly.
  2. To learn and follow the principles and methodologies in evaluating design tolerances through a disciplined approach.
  3. To Assess tolerance stickup approaches on GD&T specified parts for application proficiency

Underpinning Knowledge:

  1. General Tolerance Concepts.
  2. Types of Fit Systems.
  3. Tolerance Analysis Methods.
  4. Statistical Sampling and Tolerance Setting in Tolerance Stackup and Analysis
  5. Statistical Stack-up Methods, Toleranced-Based Analysis, Computer-based Stack Tolerancing methods.
  6. Tolerance Allocation Methods.
  7. Tolerance Analysis and Stackup Concepts with GD&T for Part Stacks.
  8. Tolerance Analysis and Stackup on Size Limit Transfer for Part and Assembly Stacks.
  9. Tolerance Analysis and Stackup on Axis Transfer for Part and Assembly Stacks.
