Blueprints in Manufacturing
Flexible Manufacturing
Lesson Plan
Performance Objectives
After completing this lesson, the students will be able to explain and read blueprints, charts, and diagrams to
the satisfaction of the teacher.
Specific Objectives
 Explain different types of blueprints, charts, and diagrams used in flexible manufacturing.
 Identify information included in a blueprint (i.e., dimensions, locations, material, and finished part).
 Identify types of lines used in a blueprint.
 Identify types of charts used in creating a blueprint (i.e., bill of materials, tap sizes, drill sizes, feed and
cut rates).
 Explain how to use information in charts to create a blueprint.
 Create a simple plan and bill of materials.
Terms
 Blueprints- describe the part to be made; show dimension, location, material, and finished part
 Charts- list information in table form
This lesson should take approximately 55-65 minutes to teach and 55-65 minutes for each of the two lab
sessions.

TEKS Correlations
This lesson, as published, correlates to the following TEKS. Any changes/alterations to the activities may result
in the elimination of any or all of the TEKS listed.
Flexible Manufacturing
 130.327 (c)
o (8) The student applies the technical concepts and skills of the sheet metal industry to
simulated and actual work situations. The student is expected to:
(B) interpret blueprints, drawings, charts, and diagrams as related to the sheet metal
industry.

Interdisciplinary Correlations
Algebra I
 111.32 (b)
o (1) Foundations for functions. The student understands that a function represents a
dependence of one quantity on another and can be described in a variety of ways. The student
is expected to:
(D) represent relationships among quantities using concrete models, tables, graphs,
diagrams, verbal descriptions, equations, and inequalities.
Geometry
 111.34 (b)
o (5) Geometric patterns. The student uses a variety of representations to describe geometric
relationships and solve problems. The student is expected to:
(B) use numeric and geometric patterns to make generalizations about geometric
properties, including properties of polygons, ratios in similar figures and solids, and
angle relationships in polygons and circles;
(C) use properties of transformations and their compositions to make connections
between mathematics and the real world, such as tessellations; and
(D) identify and apply patterns from right triangles to solve meaningful problems,
including special right triangles (45-45-90 and 30-60-90) and triangles whose sides are
Pythagorean triples.
o
(6) Dimensionality and the geometry of location. The student analyzes the relationship
between three-dimensional geometric figures and related two-dimensional representations
and uses these representations to solve problems. The student is expected to:
(A) describe and draw the intersection of a given plane with various three-dimensional
geometric figures;
(B) use nets to represent and construct three-dimensional geometric figures; and
(C) use orthographic and isometric views of three-dimensional geometric figures to
represent and construct three-dimensional geometric figures and solve problems.

Introduction
The main purpose of this lesson is to help students understand and interpret blueprints, drawings, charts, and
diagrams as related to the metal industry.


Ask
o Have you ever been given a set of plans or blueprints and not understand all of the information?
o Can you design and produce a simple set of plans to be used in class?
Say
o I have passed out different plans for you to read and answer questions about during the presentation
and for the rest of the class time.
