ME 202 Worksheet 6 – Design Notebook Laser Cut Cardboard Part 2 FALL 2011 Due Date: 10/18/2011 Objective

The purpose of this project is to begin a design process that will result in the use of solidworks and the Epilog Laser Mini laser cutter to construct a model from laser-cut cardboard. This object can be a model of a practical item, a toy, or a piece of art. You can come up with your own design.

Most objects in your environment are built in a manner that allows many millions of identical objects to be quickly, cheaply and effectively reproduced. This is known as mass-manufacturing. However, engineers can encounter many circumstances where a single object needs to be fabricated, usually in order to test the design and assembly of a new product before a costly mass-manufacturing strategy is implemented. This is known as prototyping. Laser-cutting is one of many methods that are used to produce single objects, or small lots of the same object.

Procedure 1. Create another design notebook entry that builds on top of the first assignment in this series. 2. Follow the “Engineering notebook rubric” rules when you are doing this assignment. 3. Generate a preliminary set of solidworks parts and assemblies of your laser-cut cardboard design. 4. Make all parts at 1:1 scale (actual size). 5. Account for the cardboard thickness and consider tolerances when designing your parts. 6. Make printouts of your parts, assemblies, and exploded views and put them into your design notebook. Add notes and discussion about them in the notebook. 7. Consider rigidity issues. What parts of your design are likely to be weak? Make design changes as necessary to strengthen the parts of the assembly that are likely to cause problems. 8. Turn your work in with your previous notebook entry for grading.
