Geometric Dimensioning and Tolerancing to ASME Y14.5 – Level 2

What is it?

An intensive two-day course in Geometric Dimensioning & Tolerancing, which follows on from, and builds upon, the Level 1 course.

• Learn how to define more advanced datum structures.
• Find out how to use the Least Material Condition modifier.
• Discover how to use the Maximum Material Condition modifier with datum references (datum shift).

The course covers some of the more advanced concepts of Geometric Dimensioning & Tolerancing and its application and interpretation. It is suitable for anyone who has completed the Level 1 course.

Duration

2 days for classroom delivery; 3 days for on-line delivery.

Who is it for?

Mechanical, design and production engineers.

Delegates are required to have completed the Level 1 course.
