Textbook: Hammer’s Blueprint Reading Basics, 4th ed., by Charles Gillis, Industrial Press
Workbook: Engineering Drawings Primer Workbook, by Charles Gillis
Description
Intended for the professional or manager seeking an awareness of dimensioning and tolerancing who does not need to further their knowledge with a more in-depth course. Designed to provide you with an understanding of GD&T fundamentals, this course focuses on the basic requirements of engineering drawings, numeric dimensions and tolerances, and geometric dimensions and tolerances.
Who Should Attend
This course is designed for engineering managers and supervisors, mechanical engineering technicians, manufacturing engineering technicians, quality assurance technicians, and supplier quality engineers.
Learning Objectives
Through training, participants will learn the following:
- Calculate minimum and maximum allowable values for dimensions considering numeric tolerances.
- Learn how geometric tolerances supplement conventional tolerances to specify limits on allowable variation.
- Recognize the symbols used with the geometric system of tolerances.
- Recognize basic dimensions on prints and understand their meaning.
- Identify and properly read feature control frames.
- Recognize when bonus tolerance is available and calculate geometric tolerance values when bonus tolerance applies.
- Recognize datum feature identifiers applied to features with size and surfaces.
- Analyze the datum reference frame including order of precedence.
- Identify and read geometric controls on location, orientation, form, profile & runout.
Course Outline
The Basics of Manufacturing Prints
What manufacturing prints are and why they are used
Who uses them and how

Determining tolerance values for numeric tolerances given implicitly, explicitly, symbolically, and by limit dimensioning
Calculating tolerance accumulations
Geometric Tolerance Fundamentals
How geometric tolerances work
Thinking of parts as collections of features not dimensions
