GD&T is a system of symbols and notes used on engineering drawings to specify the amount of variation from the CAD model that a manufactured part is allowed to have. Also known as the tolerances, this allowable variation has a profound impact on the manufacturing and quality inspection plan for any part. GD&T is used to ensure that everyone is on the same page regarding how the features on parts are defined. When a design engineer releases a drawing to be produced, they need a common technical language for communicating exactly what must be produced. GD&T is the language used during that communication.

Course Outline:

• The Basics of Manufacturing Prints
• Dimensions
• Numeric Tolerances
• Geometric Tolerance Fundamentals
• The Datum Reference Frame Concept
• Interpretation of Geometric Controls

Students will be able to:

•  Calculate minimum and maximum allowable values for dimensions considering numeric tolerances.
• Learn how geometric tolerances supplement conventional tolerances to specify limits on allowable variation.
• Recognize the symbols used with the geometric system of tolerances.
• Recognize basic dimensions on prints and understand their meaning.
• Identify and properly read feature control frames.
• Recognize when bonus tolerance is available and calculate geometric tolerance values when bonus tolerance applies.
• Recognize datum feature identifiers applied to features with size and surfaces.
• Analyze the datum reference frame including order of precedence.
• Identify and read geometric controls on location, orientation, form, profile & runout.

Who Should Attend:

• Engineering managers and supervisors
• Mechanical design engineers & engineering technicians
• Quality Control personnel
• Machine shop and tool room supervisors
• Supplier quality engineers
