Preproduction Engineering Design Can you design your own

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 Transportati on 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. Receiving Dept. F Dept. E Dept. A Dept. G Dept. D Dept. B Dept. H Dept. C Shipping

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.

Power. Point Presentation Combine all of your information into a Power. Point 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.
