Course Description
This intermediate course provides a deeper focus of the rules, standards, and practices used to design, draw, dimension, and tolerance simple mechanical components and assemblies. The use of computer-aided design (CAD), engineering design standards, and vendor-supplied specifications in the design process are covered. Orthographic and detailed assembly drawings are developed to scale, dimensioned, and drawn to acceptable professional standards.
Core Course Performance Objectives (CCPOs)
- Produce mechanical component drawings to acceptable American National Standards Institute (ANSI) standards. (CCC 1,2,4,5,6; PGC 1,2,3,4,5,6)
- Produce mechanical device assembly drawings to acceptable ANSI standards. (CCC 1,2,4,5,6; PGC 1,2,3,4,5,6)
- Employ various methods of dimensioning and tolerancing mechanical components and assemblies. (CCC 1,2,4,5,6; PGC 1,2,3,4,5,6)
- Compare, select, and use common types of bolts, studs, threads and fasteners in mechanical component and assembly designs. (CCC 1,2,5,6; PGC 1,2,3,4,5,6)
- Interpret basic machine blueprints used for engineering and manufacturing. (CCC 1,2,4,5,6; PGC 1)
- Interpret blueprint notes, geometric dimensions, change orders, and specifications as they pertain to the manufacturing industry. (CCC 1,2,5,6; PGC 1)
- Interpret sheet metal, mechanical, electrical, and welding blueprints used in industry. (CCC 1,2,5,6; PGC 1)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.
