Applications of GD&T Course

Who should attend: This seminar is intended for those who have already taken a fundamentals course in geometric dimensioning and tolerancing in accordance with the ASME Y14.5 standard. When representatives from design, quality, production and suppliers can attend, this course is most effective.

Course description: (16 hours) Participants will learn how to apply GD&T to a variety of situations including your own parts. Sharpen your Geometric Tolerancing skills, fill in gaps, get your questions answered, make GD&T more useable, reduce product cost, improve datum selection and create robust designs. Learn how to use the GD&T Hierarchy. Advanced concepts on the application of profile and position as well as fixed and floating features will be discussed. Learn how to properly select datum features and allocate tolerances. Expand knowledge of simultaneous requirements, composite tolerancing, profile tolerancing, robust design and boundary calculations.

Extra benefit: Bring your drawings and questions to this intense training seminar.
