Geometric Dimensioning and Tolerancing per ASME Y14.5-2018

This 16 hour course will be delivered in 4 session, each session will be 4 hours.  This course will be an instructor led on-line delivery. This course will provide practical hands-on exercises to ensure effective comprehension of the concepts and encourage questions and effective discussions. The exercises are designed  to show how tolerancing works on real working parts.

Who Should Attend

This GD&T training course is designed for precision manufacturing personnel, quality control personnel, shop floor managers and supervisors, Machine tool setup personnel, CAD technicians, Gage designers, Tool Makers, Precision Machinists and other personnel responsible for design or interpretation of Engineering drawings

Instructor: Walt Prystaj

Learning Objectives

Upon completion of GD&T training, participants will be able to:

• Identify the types of functional geometric characteristics existing on parts, realize the limitations of numeric tolerances, and understand the need for geometric tolerances.
• Analyze tolerances expressed numerically and calculate minimum and maximum allowable values for dimensions.
• Understand and apply the symbols used with the geometric system of tolerances.
• Recognize basic dimensions on prints and properly interpret their meaning.
• Evaluate inspection data in consideration of tolerance zones defined by geometric controls.
• Apply tolerances with bonus when suited to the application and properly interpret tolerances when bonus tolerance applies.
• Identify and properly interpret geometric controls on location, orientation, form, profile & runout.
• Recognize datum feature identifiers applied to features with size and surfaces.
• Identify and interpret the datum reference frame including order of precedence.
• Create specifications using appropriate geometric tolerances and datum reference frames.
