ME 340-2 Course Objectives

  1. Students should be able to design plastic parts with all the necessary details to assure manufacturability of the parts. Designs should be clear and understandable.
  2. Students should be able to create these designs in a solid modeling software package. Unigraphics in the case of this course.
  3. Students should be able to use Dimensioning & Tolerancing where appropriate to complete these designs.
  4. Students should be able to generate NC machining code (i.e., G-code) of a desired shape.
  5. Students should be able to understand the basic fundamentals in the core of CAD, i.e., data transformation and key characteristics of curve representations, and some CAE concepts.
  6. Students should be able to grasp the essence of statistical tolerances, i.e., how to specify tolerances based on the function requirement of an assembly, how to select manufacturing processes based on the process capability and the cost model.
  7. Students should be able to evaluate a measurement system and understand some principals of measurements.
  8. Students will complete a full cycle 'From Art to Part', Specifically,
  9. a. Design a plastic part to be injection molded within dimensional limits.
    b. Design a plastic injection mold of the desired part
    c. Create cutting paths of molds
    d. Machine the tooling
    e. Injection molding the parts
    f. Conduct parametric study of the injection molding process
    g. Measure the obtained plastic parts using a Coordinate Measuring Machine (CMM) and a portable laser scanner
    h. Characterize the measuring systems
    i. Complete a web page for the project
  10. Students will be provided an opportunity to see how this 'From Art to Part' process is being used in industry.
