Course outline:

In-depth analysis & implications of advanced Y14.5 principles

  • Multiple feature patterns used to define a single datum & negative implications of using "non-functional" surfaces as datum features
  • 3D analysis of composite position callouts in relationship to multiple hole patterns defined as single datums
  • Calculations for determining allowable position tolerance for floating and fixed fastener designs
  • Positioning holes and patterns of holes at "zero tolerance" for optimizing manufacturability and critical cost reductions
  • Positioning functional coaxial cylinders from independent datum features vs. to each other and defined as compound datum features
  • Boundary principles used with profile for non-cylindrical shapes
  • Contoured surfaces as datum features
  • Mathematical definitions and implications of ASME Y14.5.1M-1994
  • Surface roughness implications for features of size and form constraints 

Optimization strategies in applications and analysis of design, manufacturing, and measurement

  • Common error implications of dimensioning & tolerancing of tooling and functional gaging, based on product designs
  • Negative implications of common incorrect measurement procedures on CMMs and procedures to resolve/minimize problems
  • Profile definitions and boundary implications in corner transition areas
  • Uncertainty implications of ASME Y14.5 and transformation/development efforts that affect all technical areas
  • Characterization of physical-to-functional hierarchies and the importance of this analysis to realizing optimum functional intent
  • Examination of students' drawings with an eye toward making them clearer so as to optimize design intent and maximize ROI

Advanced tolerancing development within Y14.5

  • Extension principles for datums used in non-standard designs
  • Complex 3D profile geometry and tolerance boundaries
  • Critical simplification of Y14.5
  • Statistical tolerancing

Implications of GD&T for Six-sigma initiatives and product reliability
