Classroom Training - Introduction to geometric dimensioning and tolerancing (GD&T) - Hexagon Technical Centre - 1 day

Options:
This course can be delivered to BS/ISO or ASME Y14.5 standards. We also offer a ‘Virtual’ option for both courses.


Aims and objectives
To provide:
• The underpinning knowledge and expertise for anyone whose role involves the use of geometrical dimensioning and tolerancing (GD&T).
• The principal knowledge and practical training for people who are required to use GD&T during their daily task.

Enabling:
• An understanding of some of the relevant standards relating to geometrical product specifications. Principles and tolerances associated with the measurement process and why the understanding of GD&T is so important in metrology.
• This two-day course applies to all industrial sectors from design, manufacturing, and quality control. It can be used to refresh knowledge, give a basic understanding, or used as a building block for further courses.

Course summary/agenda:
• Introduction to geometrical product specification (GPS)
• Requirements of GD&T
• GD&T standards
• Interpretation of geometrical characteristics
• The implications of using certain geometrical characteristics
• Understanding datum reference systems (primary, secondary, tertiary. 6 Degrees of freedom)
• General tolerance
• Tolerance frames
• Understanding the GD&T symbols:
• Form tolerances
• Location tolerances (including maximum material condition principle)
• Orientation tolerances
• Runout tolerances
• Profile tolerances
• Surface texture principles
• New symbology
• Advanced features

Intended audience:
• Design staff who need to understand measurement principles
• Anyone using measurement equipment in the workplace
• Manufacturing and engineering personnel
• Production supervisors and managers
• Quality control personnel
• Measurement technicians
• Process planners
• Apprentices

To enhance knowledge, transfer the course involves workbook and practical exercises covering all aspects.
