Content
  • Fundamentals of GD&T based on ASME Y14.5-2009, focusing on precise communication, tolerance design, and functional dimensioning.
  • Functional adjustments, Relationship between IT and process capabilities
  • Analysis of dimensional variations, Coastline, Tolerance analysis methods, Use of WORST CASE and STATISTICS methods
  • Understanding virtual size for precise engineering tolerances
  • Modifiers, Maximum Material Condition (MMC), Minimum Material Condition, Projected Tolerance Zone, Free State
  • Calculation of geometric shape tolerances, Seal, Support – Assembly with interference
  • "Study of geometric profile tolerances, controlling shape deviations for precision parts in engineering."
  • Geometric location tolerances – Position tolerances

With its dimensions and tolerances content, technical drawing is a language that wants to be common to all. It is composed of a set of standards, symbols and very precise rules allowing conveying the geometrical characteristics of a part or an assembly.

The designer, technician and operator use it when designing and manufacturing mechanical parts. It is also used for process selection during production planning and manufacturing ranges. The proper realization of the parts and the inspection of the parts require the correct interpretation of the information communicated by this language.

Level 2- Design with the ASME Y14.5-2009 geometric dimensioning and tolerancing standard
Goals

The aim of the training in this module is to familiarize users with advanced notions of geometric tolerancing and methods for calculating geometric location and shape tolerances in technical drawings of mechanical components. 

At the end of the training, the participant must be able to master variation analysis techniques (Chain of dimensions), the concept of virtual size, modifiers and calculation of tolerances of locations and profile according to the ASME Y14.5 standard.

Target Audience
Mechanical engineers, industrial designers, QC technicians, inspectors
Content
GD&T principles and symbols per ISO and ASME Y14.5, datum systems, zone tolerance, stack-up analysis, industrial drawing examples
