Course Description
This course explores how to read and create good mechanical working drawings, and how to create and evaluate good 3D models of parts and assemblies. This is done by utilizing drafting concepts in both hand-sketching and computer-aided solid modeling following current mechanical engineering standards.
Core Course Performance Objectives (CCPOs)
- Interpret mechanical drawings. (CCC 1, 2, 5, 6; PGC 4)
- Hand sketch designs using graph paper. (CCC 1, 2, 5, 6; PGC 4)
- Create computer-aided design/drafting (CAD) generated detail and assembly working drawings using proper dimensioning and annotation techniques. (CCC 2, 5, 6; PGC 4)
- Produce solid models and machine assemblies using 3D solid modeling software. (CCC 1, 2, 3, 5, 6; PGC 4)
- Create a product prototype using additive manufacturing. (CCC 1, 2, 3, 5, 6; PGC 1,4)
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:
- Interpret mechanical drawings.
- Identify and use common line styles properly, including object lines, hidden lines, center lines, extension lines, dimension lines, and cutting plane lines.
- Read size and location dimensions.
- Interpret and apply hole and thread notes.
- Discriminate between good and poor dimensioning practices.
- Discriminate between the possible orthographic and specialty views.
- Hand sketch designs using graph paper.
- Draw appropriate orthographic, isometric and specialty views (detail, auxiliary etc.) using proper line types.
- Add dimensions following the applicable standard.
- Create computer-aided design/drafting (CAD) generated detail and assembly working drawings using proper dimensioning and annotation techniques.
- Select the best front orthographic view.
- Identify the required number of additional orthographic views and place according to 3rd angle projection.
- Create shaded isometric views.
- Create any specialty views (detail, auxiliary, sections, exploded) to fully define the part.
- Add primary and secondary center lines as required.
- Dimension the drawing following the applicable standard.
- Add text to the drawing for title block information and notes as required for manufacture/assembly.
- Identify and specify proper tolerancing as needed.
- Produce solid models and machine assemblies using 3D solid modeling software.
- Fully constrain sketches using given dimensions and geometric relations.
- Create parts using an efficient choice of features (revolve, extrude, thread tool).
- Set material of part files.
- Create working assemblies of parts in a logical physical order, using an efficient choice of mates.
- Evaluate parts and assemblies for strength, interference, and collision.
- Create a product prototype using additive manufacturing.
- Design, develop, and produce a 3D product using additive manufacturing.
