https://manabernardes.com/2024/flrdq53p Course Description and Objective:

This course is targeted for those people who have to read part and assembly drawings as part of their job; such as operators, quality control technicians, set-up personnel, quality engineers, supplier quality engineers, manufacturing engineers, product engineers (also for design purposes), and drafting personnel (for design purposes). Their immediate supervisors could also benefit from this course by becoming more effective communicators with the employees.  This course covers the basics of reading and interpreting geometric dimensioning and tolerancing information on prints.  The course objectives are to establish a basic level of skills to correctly use prints that contain GD&T information.

To accomplish this objective, the course is divided into several main sections.  The first portion of each section is material and discussion related and the second section is an assessment for the attendee’s benefit; each section will be approximately 1 hour. Several aspects of the GD&T language will be covered which will allow the attendee to correctly interpret many different types of parts and assembly drawings that have varying degrees of complexity.

This course is facilitated by Phil Ross

https://modaypadel.com/pwvbhxpw II. GD&T Principles:

In this section the general concept of how GD&T works is explained. The later sections go into greater depth of major considerations of GD&T. GD&T is really a common language for graphically describing the physical aspects of various parts. Because of GD&T being a “language,” there are certain required rules and syntax to be used to keep the interpretation consistent from user to user.

https://serenityspaonline.com/qw54qc6tgu III. Datums

Datums are the starting point for GD&T. The datums provide a frame of reference like a Cartesian coordinate system, either 2 or 3 dimensional, depending upon part functionality. How parts contact one another and what function a specific part feature might have generally determine the datums from which all other features are dimensioned and measured. Datums may be in the form of planes, diameters, or angled surfaces depending upon part design and form the foundation of the GD&T principle.

Once datums have been established, all other features relate to those datums. The relationship is both in terms of basic position of the feature and the tolerance allowed for that specific feature. Tolerances may be in the form of position, flatness, straightness, parallelism, perpendicularity, profile, cylindricity, concentricity, or runout depending upon the part and feature functional requirements. Usually, there are several ways to tolerance a given part characteristic, but how parts contact one another typically drives the type of tolerance used for a given feature. Understanding the differences among all the feature tolerances is essential for proper application of GD&T information.
