Applied Geometrical Tolerancing for PC‐DMIS

Geometric Dimensioning and Tolerancing (GD&T) is the common, powerful language of industrial manufacturing. GD&T is recognized around the world as the only way of defining engineering drawings and CAD models efficiently and unambiguously. But the unfortunate reality is that most of the workforce that engages with mechanical drawings has an adequate understanding of this language. Many individuals and organizations get by for some time before costly or otherwise painful experiences convince them they need to improve their skills in use of GD&T.
The truth is that properly applied at the earliest stages of a product development project, GD&T can establish robust product quality, save months of development time, tens even hundreds of thousands of euros, and potentially millions over the lifecycle of a product.
GD&T training has real benefits: lower costs, less non‐conforming parts, higher tolerances.
InQuality, authorized partner of HEXAGON MI, offers on‐site and on‐line GD&T training courses.
Based on the latest ISO & ASME standards, our courses are tailor‐made to fully cover your particular needs.

Aims & Objectives

The course is delivered as an intensive, two‐day programme for users of PC‐DMIS metrology software and applies GD&T from a measurement/ inspection perspective. The aim of this course is to teach how to properly implement geometrical tolerance specifications with PC‐DMIS.
Participants will be guided to “connect the dots” between their GD&T knowledge and its application on PC‐DMIS metrology tasks, will discover how the different types of geometrical specifications are “translated” in PC‐DMIS measurement programs and will understand the advanced inspection techniques offered by the
latest versions of the software.
The focus of the course is utilizing Geometric Tolerance commands that were introduced in the 2020R2 PC‐DMIS version, however, some references to Legacy and Xact Measure GD&T commands are considered.
The course includes extensive classroom discussions, team exercises and problem‐solving sessions. Examples of drawings or components from the client, where available, are used in order to illustrate the course material. CMM hands‐on mini workshops can be included, on sites where the necessary equipment is available (CMM+PC‐DMIS). Suggestions to customize the course to specific participant needs can be discussed. To maximize the effectiveness of the training, an upper limit to the class size of 10 delegates is recommended.

Who it may concern

This course specifically designed is for PC‐DMIS PRO, CAD and CAD++ users with both Manual and DCC coordinate measuring machines.
Prior GDF&T knowledge of fundamental concepts, such as Level‐1 GD&T course is strongly recommended.

Course topics

  •  Standards in context
    Τhe ISO system and the GPS (Geometrical Product Specification) Method vs ASME (GD&T), relevant national standards, future development
  • Introduction to PC‐DMIS Geometric Tolerance commands and Feature Control Frames
    Structuring PC‐DMIS measurement routines for Geometric Tolerances dialog box usage and command syntax
  • Feature Types
    Features of Size
    Deriving the Toleranced Feature
  • Geometric Tolerance Types
    Location, orientation, form and runout tolerances (ISO 1101:2017) profile tolerances ( ISO 1660:2017)
  • Tolerance frame modifiers
    Maximum Material Requirement and Bonus Tolerance (as per ISO 2692:2021)
  • Evaluating Linear size tolerances with the Geometric Tolerance Command
    Dimension a feature using the SIZE Option, the Envelope Requirement using the Size command supported ISO 14405‐1 modifiers

After the course the participants will be able to:

Have an essential understanding of all the symbology used in ASME GPS system, how it's used to meet design intent and remove ambiguity.
Understand how the geometrical charactistics of features determine their functionality.
Understand how datums and theoretically exact dimensions work, what they are for and how to select them.
Understand the 14 types geometric tolerances, how they are related and what each one will control.
Understand how each and every one of an array of tolerance zone modifiers may used to increase or refine tolerance whilst ensuring the features meet their functional requirements.
Recognize the correct functional application of GD&T.
