  1. A new kind of scratch The Dream Team: Sean Keefe, Lucien Filip, Aaron Alves, Manuel Boria, Matt Baxter http://myweb.wit.edu/filipl/Courses/mech163/majorproject.htm

  2. Abstract • We redesigned a scribe and a combination square in order to make it more efficient. • This is more efficient because materials are capable of being scribed at any angle and smoothly. • This new scribe is able to fit pieces that range from one foot to three feet.

  3. Needs Assesment • We assessed the needs of our project based on the following categories: • People- the users interaction with the product • Materials- what the product is constructed of • Machine- how the product is produced • Procedure- how the product is used

  4. Background • While in our manufacturing lab we had to scribe lines on sheet metal for measurements. • Scribing these lines was difficult and consumed too much time and the lines weren’t smooth. • This led to the idea of reconstructing this tool for easier use.

  5. Problem Formulation • Problems in the current design arise from a number of difficulties: • Awkward handling • Limited scribe length • Angles are difficult to scribe

  6. Methodology • First we constructed an ishikawa diagram to analyze the problems of the existing tools. • Then we created a prototype and had rough sketches and autocad diagrams to analyze the features. • Future plans to manufacture the prototype and test it out.

  7. Alternative Solutions • After testing out prototypes the most efficient design of rotating the center piece should be found • This will make the product have maximum range and minimal difficulty to use

  9. Materials To Be Used • Combination edge made of a Hard grade plastic. • Ruler constructed out of Steel. • Scribe made out of stainless steel.

  10. Ideal Procedure • Mold the combination edge in a cast • Attach the metal ruler aligned to the center • Attach the sliding scribe to the metal ruler

  11. Conclusion • Finally there are four reasons why it is worth producing this new combination tool: • Cheap to make • Easy to use • Very versatile • Efficient
