EDT 252 Engineering Design III

This advanced course provides an overview of the rules, standards, and practices in designing, drawing, dimensioning, and tolerancing mechanical components and assemblies. The use of computer-aided design (CAD), engineering design standards, product end-use requirements, manufacturability considerations, and vendor-supplied specifications in the design process are covered. Original designs for complex functional mechanical components and systems are developed, dimensioned, and drawn to acceptable professional standards.

Core Course Performance Objectives (CCPOs)

  1. Apply drafting standards and techniques to develop and document design information for complex mechanical components drawn to American National Standards Institute (ANSI) and/or other applicable industry standards and conventions. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 2, 3, 4, 5, 6)
  2. Use conventional and geometric tolerancing techniques to accurately define mechanical component and assembly designs for manufacture. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 2, 3, 4, 5, 6)
  3. Apply basic mechanical design principles, reference materials, and standards to develop mechanical designs. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 2, 3, 4, 5, 6)
  4. Use engineering documentation procedures to produce and maintain an accurate and up-to-date set of engineering drawings and specifications. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 2, 3, 4, 5, 6)

See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

Measurable Performance Objectives (MPOs)

Upon completion of this course, the student will:

  1. Apply drafting standards and techniques to develop and document design information for complex mechanical components drawn to American National Standards Institute (ANSI) and/or other applicable industry standards and conventions.
    1. Use the design constraints process to develop and generate computer-aided design (CAD) based working drawings from design guidelines.
    2. Create a complete and accurate engineering title block.
    3. Correctly identify, illustrate, and interpret common weld symbols and explain their implications relative to weld fabrication.
    4. Design a simple mechanical assembly for fabrication as a weldment.
    5. Correctly use orthographic, auxiliary, sectional, and isometric views with all required dimensions, tolerances, and notes to fully define a complex mechanical component for manufacture.
  2. Use conventional and geometric tolerancing techniques to accurately define mechanical designs and assembly designs for manufacture.
    1. Evaluate and create limit dimensions for common mechanical geometries.
    2. Describe and apply nominal sizes and stock sizes in the design of complex mechanical components.
    3. Design mating parts and assemblies using limit dimensions, unilateral tolerances, and bilateral tolerances.
    4. Describe and properly apply clearance fits, interference fits, and transition fits.
    5. Describe and properly apply tolerances and finishes needed for machining mechanical components.
    6. Illustrate, apply, and explain the functional implications of common geometric tolerances.
  3. Apply basic design principles, reference materials, and standards used to develop mechanical designs.
    1. Define the principles and advantages of designing from stock shapes.
    2. Locate and accurately apply engineering design information from references such as the Machinery's Handbook and vendor-supplied technical data.
    3. Complete a basic stack tolerance analysis on a mechanical component or assembly.
    4. Use engineering design standards, product end-use requirements, manufacturability considerations, and vendor-supplied specifications in the design process.
  4. Use engineering documentation procedures to produce and maintain an accurate and up-to-date set of engineering drawings and specifications.
    1. Produce a complete set of drawings, including individual detail drawings, three-dimensional (3D) assembly drawings, isometric or 3D exploded views, parts lists, design constraints, and bill of materials (BOM) for a detailed mechanical assembly.
    2. Develop and explain the rationale behind a part numbering system for a mechanical assembly and/or product line.
    3. Write an engineering change notification for a mechanical design, and explain the implications of keeping such a system up to date in an engineering and/or manufacturing operation.
