Preproduction:
Engineering Design
Can you design your own product?
Your Challenge
Throughout this project, you will walk through the
engineering design process from start to finish ending
with a completed prototype and a presentation that
could be given to a company to sale your design.
In the second part of this unit you will be completing the
production plan for your design.
As a team you should complete the steps below in your
design notebook:
Tooling



Copy the following chart in your notebook and list each type of
tooling needed to produce your product.
Remember that tooling can increase your speed and accuracy of
your production and final product.
Create drawings and write descriptions of any jigs and fixtures
you need.
Part of Product
Material
Tool Needed
Tooling Needed
Quality Control


Establish guidelines for quality control.
At what points of production will you do a quality
control check and what will the criteria being
checked be?
Flow Process Chart


Show a the step-by-step process
for producing a single part.
 Describes the task
 Provides a code number for
each task
 Identifies the machines used
 Lists tooling needed for the
task
Standard symbols are used to
identify each task that were
developed by the American
Society of Mechanical Engineers
(ASME)
Process Flow Chart Symbols
Operation
Object is changed
in its chemical or
physical makeup; it
is assembled or
disassembled
Transportation
Object has moved
from one place to
another
Inspection
Object is checked
against quality
standards
Delay
Storage
Object is held for
the next operation
Object is placed in
a protected
location
Flow Process Chart

Using the flow process chart worksheet, create a
flow chart for each part.
Operation Process Chart




An operation process chart shows how each part is
made and then show the assembly of the product.
Transportation, delay, and storage tasks are not
included in the chart.
The operations process chart is used in scheduling
production. It shows what parts need to be finished
at what time frame. This reduces the storage
needed.
JIT- “Just is time” – parts arrive just in time for
assembly. This helps reduce costs.
Example: Operation Process Chart
Create an operation process chart for each piece.
PLASTIC
CLIP
1. Cut to width
2. Cut to length
3. Drill holes
4. Round corners
5. Assemble to clip
Process Layout – Facility Layout



Groups machines by the
processes they perform.
Most common in custom
manufacturing and
intermittent manufacturing
A plant can produce a
number of different
products and machines can
be used for a variety of
tasks.

Process Layout – Facility Layout


Complete a facility layout plan for your product.
Keep in mind that your facility layout can play a
large role in the efficiency of your production.
PowerPoint Presentation

Combine all of your information into a PowerPoint
presentation.

All sketches should be scanned and placed in the
presentation.
Rubric


You will be presenting
your information to the
class before
proceeding to part 2
of the overall project.
Classmates may make
suggestions that should
be documented and
considered during the
presentation.
