Content
  • Introduction to dimensioning and tolerancing, fundamental concepts and importance in design
  • Basics: adjustments, envelope principle, tolerance stack-up, and tolerance zones
  • Symbolism in technical drawings, minimal dimensioning, and 3D annotation principles
  • Geometric tolerances and modifiers including MMC, LMC, projected, free state, and functional symbols.
  • Datums and references: six degrees of freedom, double referential, targeted reference systems
  • Geometrical shape tolerances: straightness, flatness, line and surface profiles, measurement
  • Geometric location tolerances: position, orientation, alignment of features in assemblies
  • Relational tolerances: parallelism, perpendicularity, angularity, and synthesis exercises

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.

Goals

The purpose of this module is to familiarize the student with the basic concepts of dimensional tolerance and the interpretation of dimensional and geometric information contained in the technical drawings of mechanical components.

At the end of the training, the participant must be able to interpret the tolerances on a technical drawing according to ASME Y14.5.

Target Audience

Laboratory technicians, quality engineers, precision measurement operators

Content

Type A and B uncertainty, random and systematic errors, repeatability, international standards, use in GD&T inspection

Method

Theory + real data exercises + numeric analysis

Application

Assessing measurement reliability in quality control and product validation
