ME 116 Engineering Drawing II

Project

The objective of this project is to utilize 3-D modeling and CAD skills to produce a complete and robust model and set of production drawings which could be used in the fabrication of a product. Dimensioning schemes and model creation strategies should be consistent with common manufacturing processes. Consideration should also be given to the fact it may be necessary to modify the design in the future, and the model should be able to be edited with as little effort as possible. A complete engineering drawing of each part must also be included. Each part should be drawn on its own sheet, including title block with references to part identification, material information, and any other relevant annotations. Drawings should be produced with scale factors and other parameters chosen appropriately for the size of the part and the sheet size being used. Also, assembly and exploded view drawings, including a Bill of Materials, must accompany the drawing set, complete with all necessary annotations. The student is encouraged to consult outside sources for appropriate dimensions and annotation standards, as well as to clarify unknown terminology. Suggested resources include: The Machinery’s Handbook, the internet, and the library. The project will be graded on adherence to technical standards, overall aesthetics, and the accuracy and completeness of the final models and drawings. This project is due at the beginning of the Final Exam. A hard copy of all part and assembly drawings must be submitted with a title page and table of contents. An electronic copy of the entire project will be submitted in a .zip file uploaded to Blackboard, in the same fashion as the homework. A sample project is attached. The project is sufficient for this course. Outside projects are encouraged; however, the project must be approved by the instructor for appropriate difficulty and complexity. Declaration of the chosen project is due no later than one week from project assignment.

Project Checklist

o Robust, dimensionally accurate 3-D models of all parts. Commercially available parts such as screws, bolts, and nuts may be downloaded.

o Complete engineering drawings of each part. Drawings must include all necessary

dimensions and views, and be placed on A or C sized paper. Commercially available parts do not require a drawing, but should be referenced by part number and manufacturer/supplier.

o Each drawing must have a title block which should include the following information o Students name o Part name and description o Material identification o Any other relevant information

o Assembly of the finished project, with all parts fully constrained. Use of subassemblies

is encouraged if appropriate to the project.

o Exploded views with positions of parts modified for clarity.

o Engineering drawings, with title block as described above, of the finished assembly and exploded views. Assembly drawings must include a Bill of Materials, and annotations indentifying each part.

o Hard copy to be submitted at the time of the Final Exam, consisting of all part and assembly drawings, with title page and table of contents.
