ET2053: Fundamentals of GD&T for Inspectors - Foundational Level

Abstract

Content: This 2-day foundational-level course builds on geometric dimensioning and tolerancing fundamentals and teaches an introduction of how to inspect GD&T requirements. 

The course offers an explanation of the geometric symbols, rules, and concepts, the datum system, and how to inspect GD&T requirements using tools from the four categories of inspection tools (CMM; comparison instruments and fixed gages; hand tools and open set up; and production gaging systems).
Each participant receives: A Fundamentals of GD&T for Inspectors Workbook The Fundamentals of GD&T (ASME Y14.5M-1994) textbook by Alex Krulikowski A GD&T Ultimate Pocket Guide (1994) Class handouts
Newly acquired learning is reinforced throughout the class with numerous practice problems. The scope of the workshop includes how to locate a part for CMM inspection but not how to program the CMM to gather the data point.

Learning Objectives

Content

After completing this course, you will be able to:

Describe inspection and engineering drawings
Explain key terms used in GD&T and how they affect interpretation and inspection
Recognize the modifiers and symbols used in geometric tolerancing
Interpret and inspect Rule #1, Rule #2, flatness, straightness, circularity, cylindricity, perpendicularity, angularity, parallelism, concentricity, symmetry, circular and total runout
Explain the concepts of basic dimensions, virtual condition, inner and outer boundary and bonus tolerance and their effects on inspection
Interpret and simulate planar datums and datum targets for inspection
Interpret and inspect feature of size datums RFS and MMC
Explain the fundamental concepts of tolerance of position: definitions, conventions, advantages and interpretations and their effects on inspection
Interpret and inspect tolerance of position RFS, MMC, and special applications
Describe functional gages for tolerance of position (MMC) applications
Explain profile tolerancing
Interpret and inspect profile of a surface and profile of a line applications

Who Should Attend

Content: This course is valuable for individuals who create or interpret engineering drawings, product and gage designers; process, product, and manufacturing engineers; supplier quality engineers/professionals; CMM operators; buyers/purchasers; checkers; inspectors; technicians; and sales engineers/professionals.

Prerequisites

Content: Participants should have basic knowledge and command of the GD&T ASME Y14.5 standard, which provide guidelines for engineering drawing sheet layout.
