http://catalog.sierracollege.edu/course-outlines/engr-0137/

Catalog Description DESCRIPTION IS HERE: Formerly known as ENGR 37 Advisory: Completion of ENGR 151 with grade of "C" or better Hours: 90 (36 lecture, 54 laboratory) Description: Application of multiple fabrication techniques including tools and materials required for the manufacture of a mechanical assembly. Introduction to design and documentation of a final product. Manufacturing processes in the areas of forming, joining, material removal, casting, welding, assembly and prototyping which includes hands on use of manufacturing equipment. Each student fabricates a final project based on principles of manufacturing. (CSU, UC) Units 3 Lecture-Discussion 36 Laboratory 54 By Arrangement Contact Hours 90 Outside of Class Hours Course Student Learning Outcomes Analyze and interpret engineering drawings. Set up and operate common manufacturing machines (shaping and joining using the mill, lathe, welder, 3D printer, etc.) Summarize and utilize best practices for operating hand tools found in a common machine shop. Write, describe, and produce the concepts of dimensioning and tolerancing and show the capability of both machining and measuring to those constraints. Course Content Outline 1. Safety Procedures and requirements for all tools and machines 2. Reading, understanding, and analyzing engineering drawings (part and assembly drawings) 3. Measurement and calculation 4. Project introduction, explanation, and procedures to fabricate parts and assemble the final product (example project: Air/steam driven engine) 5. Obtain various raw materials, including but not limited to plastics, aluminum alloys (bar stock), steels (flat stock), other metal alloys, hardware, and paint. This includes cutting bar stock, round stock, flat (band) stock, etc. 6. Use safe manufacturing techniques, including the operation of machines and hand tools to create final parts from raw materials 6.1 Drill Press 6.2 Lathe 6.3 Mill 6.4 Metal bending and forming tools 6.5 Machine shop hand tools (wrenches, file, saw, hammer, punch, etc.) 6.6 Rapid prototype (3D printing) 6.7 Welding equipment (MIG, braze, solder and cutting) 6.8 Grinding 6.9 Sanding 6.10 Hand tools (file, hammer, pliers, etc.) 7. Discuss the benefits and limitations of different engineering materials as they relate to part function and ability to manipulate/fabricate material 8. Measure final parts to verify conformance to drawings and quality control 9. Evaluate all measurements as they relate to tolerance 10. Assemble the final product 10.1 Bolting 10.2 Riveting 10.3 Sheet screws 10.4 Press fit 10.5 Torque of a bolt 10.6 Lubrication needs 10.7 Wiring 10.8 Tying 10.9 Locking compound 10.10 Sealing compound 10.11 Bonding compound 11. Discuss different manufacturing processes as they relate to efficiency and the ability to create a quality final product at a low price Course Objectives Course Objectives Lecture Objectives: 1. Demonstrate proficiency in interpreting and analyzing engineering drawings. 2. Demonstrate the method used to accurately measure linear distance and perform calculations (example: area, volume). 3. Demonstrate safe techniques for operation of manufacturing equipment (mill, lathe). 4. Compare and contrast the benefits and limitations of different engineering materials. 5. Demonstrate how to evaluate a tolerance and how to enhance manufacturing operations that improve the ability to hold a tight tolerance. 7. Explain standard assembly practices in manufacturing. 8. Compare and contrast different manufacturing processes as they relate to efficiency and the ability to create a quality final product. Laboratory Objectives: 1. Demonstrate the method used to accurately measure linear distance and perform calculations (example: area, volume). 2. Demonstrate safe techniques for operation of manufacturing equipment (mill, lathe). 3. Demonstrate how to evaluate a tolerance and how to enhance manufacturing operations that improve the ability to hold a tight tolerance. 4. Demonstrate how to operate common manufacturing machines and tools. 5. Demonstrate standard assembly practices in manufacturing. Methods of Evaluation Objective Examinations Projects Skill Demonstrations Reading Assignments 1. Read the section on drilling and tapping a hole. Come to class prepared to discuss the techniques that are found in the reading and how those will be applied in the term project. 2. Read the section on applying the proper torque to a bolt. In class, demonstrate the techniques learned in the reading by setting the proper torque to a bolt on the term project. Writing, Problem Solving or Performance 1. Create a report that summarizes the term project. This should include how it was designed, parts manufactured, assembly, and testing. 2. Fabricate and assemble all parts required to create the term project. These parts will be evaluated on how close their actual measurements relate to the plan (design given by instructor). Other (Term projects, research papers, portfolios, etc.) 1. Term Project. Example: Build an Air/Steam Drive Engine.
