CAD 137 - Geometric Dimension & Tolerancing Application

Credits: 4
Geometric Dimensioning and Tolerancing (GD&T) is an international technical language of symbols used to describe the function and relationship of a part’s feature. The symbology of GD&T, as defined in the ASME Y14.5 standard, is understood and applied by all designing and manufacturing communities. Students learn to recognize, interpret and apply GD&T theories and symbols. Students study applicable mathematical formulas. Previously D T 115.

Enrollment Requirement: CAD 101 or instructor consent.

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

Interpret drawings per current ASME Y 14.5 Standard
Describe geometric tolerancing symbols and their relative controls
Demonstrate the ability to properly identify Datums, and correct an improper identification
Create a Feature Control frame (FCF) and place properly for proper identification
Identify maximum material and Least material conditions.
Describe a tolerance zone as indicated by the controlling FCF.
Describe applicable changes to the tolerance zone with material modifiers being applied.

Program Outcomes

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.
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.
Written Communication - Written Communication encompasses all the abilities necessary for effective expression of thoughts, feelings, and ideas in written form.
