CAD 231 - Mechanical Principles of Design

Credits: 5
Teaches advanced principles, techniques and applications of drafting technology required for the preparation of detail and assembly drawings. Based on current industry practices and standards. Areas of study include dimensioning and tolerancing geometric form and positional tolerancing, shop processes and procedures, layout drawings including developments and triangulation, piping and tubing drawings, welding and welding symbols, and forging and casting drawings. Previously D T 231.

Enrollment Requirement: CAD 101 and CAD 102; or instructor consent.

Course Outcomes:
Students who successfully complete this class will be able to:

Create Bill of Materials with main assemblies and simple sub assemblies and identifying the objects properly
Identify and properly dimension FITS based on charts controlling tolerances
Identify datums and Feature Control Frames (FCF) on drawings per ASME Y14.5
Calculate hydraulic forces and motions based on given criteria.
Create motion diagram and proper cam form based on that diagram.
Calculate and create proper basic gear forms.

Program Outcomes

Identify, solve, and apply engineering principles and calculations relevant to a design project.
Apply computer and engineering office software for documentation, communication and approval within an engineering office environment.
Apply current ASME Y14.5, machining and AWS symbology for industry production and documentation.

College-wide Outcomes

Critical Thinking -Critical thinking finds expression in all disciplines and everyday life. It is characterized by an ability to reflect upon thinking patterns, including the role of emotions on thoughts, and to rigorously assess the quality of thought through its work products. Critical thinkers routinely evaluate thinking processes and alter them, as necessary, to facilitate an improvement in their thinking and potentially foster certain dispositions or intellectual traits over time.
Responsibility - Responsibility encompasses those behaviors and dispositions necessary for students to be effective members of a community. This outcome is designed to help students recognize the value of a commitment to those responsibilities which will enable them to work successfully individually and with others.
Quantitative and Symbolic Reasoning - Quantitative Reasoning encompasses abilities necessary for a student to become literate in today’s technological world. Quantitative reasoning begins with basic skills and extends to problem solving.
