Preproduction: Engineering Design

Can you design your own product?

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:

Your Challenge

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

DelayObject is held for the next operation

Storage

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

PLASTIC CLIP

1. Cut to width

2. Cut to length

3. Drill holes

4. Round corners

5. Assemble to clip

Create an operation process chart for each piece.

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.
