Geometrical Dimensioning and Tolerancing

This training is for anyone who comes into contact with geometrical tolerancing, both its application and interpretation. We often see a great deal of diversity in the application and interpretation of geometrical tolerancing. This training session strives constructively towards uniform interpretation, in order to get all of the participants on the same page.

Training objective

The main objective of the training session is to get everyone on the same page with regard to the application and interpretation of geometrical tolerancing. This training session includes time for class discussions. This fine-tunes communication and helps get everyone achive a common understanding.

By the end of the two-day training session, participants will:

• Be able to interpret indicated geometrical tolerancing correctly
• Be able to apply geometrical tolerancing functionally themselves in the formulation of product specifications and preparation of drawings
• Have an understanding of the differences between the ASME and ISO standards

General

• Maximum of 8 participants per session, in order to promote class discussion and interaction.
• The client will provide a projector and whiteboard.
• The training can be given in either Dutch or English.
• After completion, each participant will receive a certificate.

Target group

The training is designed for a mixed target group. Anyone who comes into contact with geometrical tolerancing (technical drafters, planners, etc.) is encouraged to attend. This training session can be given within an organisation, but can also be arranged for participants from different organisations.

Duration of the training

The entire “Geometrical tolerancing” training session lasts for two days, but the contents can be adapted to a particular project or product group.
