Blueprint Reading

A learned skill...
Blueprint reading is a learned skill, not
an art, as I've heard some say. Blueprints consist of three primary parts:
-
The Drawing
-
The Dimensions and Tolerances, and
-
The Notes
Let's take a quick look at each of those primary
parts.
The
Drawing...
The drawing is the most important part of blueprint reading. It
tells us what the product looks like. Blueprints can have one of three views: orthographic, perspective or
isometric. The orthographic print is the most common one used for manufacturing. Another name for an orthographic
print is multi-view.
The multi-view print allows us to
visualize the product three dimensionally in our mind. And, once we master being able to picture the product we
will master blueprint reading.
The
Dimensionsand Tolerences...
Dimensions shown on the blueprint define the requirements for fit, form
and/or function. The dimensions also include any tolerances that apply to the products features. Variation makes it
impossible to duplicate an exact dimension on every product. This is the reason designers give us
tolerances.
Tolerances allow the features of a product to vary a little from part to
part. But, not enough to stop the product from being used.
The
Notes...
The notes on blueprints
can cover many things. The designer uses notes to tell us about things that the drawing or dimensions don’t cover.
For example, “No burrs”, or “Reference Only”. Notes can be about anything the designer wants to tell the
manufacturing and quality assurance departments.
Blueprint
Reading Training
Learn the basics of reading and interpreting blueprints. Interactive
workshops help you understand and read blueprints. The students will work with the instructor and other students to
gain a better understanding of the issues they see on a daily basis.
Some of the things we cover in the
class are:
-
Types of Drawings (Isometric, Perspective,
Orthographic)
-
Points of view (Perspective,
Orthographic)
-
Projected views (Isometric,
Orthographic)
-
How to visualize the part
-
Arrangement of views
-
Number of views required
-
Auxiliary views
-
Sectioned views
-
Dimensioning Systems
-
Dimensions for Angles Rounds, Squares, and Arcs
-
Dimensions for Specific Purposes
-
Dimensions Not Shown and much more.
You can have this class presented at your
business for less than $53.00. per person.
Travel expenses not included.
The class is one day.
Who should attend?
Anyone that uses a blueprint in their
work: production people, quality techs and auditors, tooling and setup people, purchasing, and
maintenance.
