Unsettled Topics on Nondestructive Testing of Additively Manufactured Parts in the Mobility Industry

2020-09-30
EPR2020017
Additive manufacturing (AM) technology, also known as 3D printing, has transitioned from concepts and prototypes to part-for-part substitution and the creation of unique part geometries that can only be made using AM. These AM applications are increasingly present in demanding fields such as medicine and aerospace. Generally, however, the applications are still primarily driven by thermal, stiffness, corrosion, and static loading conditions. In order to move to the next levels of structural significance (durability and damage tolerance), the AM technologies and components will need to reliably demonstrate freedom from inherent discontinuities that degrade durability to the point of preventing consideration in fatigue environments. This also includes freedom from rogue discontinuities that have the same impact on damage tolerance.

Fundamentals of GD&T 2018 3-day

2020-09-22
This course teaches the terms, rules, symbols, and concepts of GD&T as prescribed in the ASME Y14.5-2018 Standard. This course offers an in-depth explanation of geometric tolerancing symbols, their tolerance zones, applicable modifiers, common applications, and verification principles. The class includes a comparison of GD&T to the directly toleranced dimensioning method; Rules #1 and #2; form and orientation controls; tolerance of position; runout and profile controls. Newly acquired learning is reinforced throughout the class with more than 150 practice problems.

Fundamentals of GD&T for Inspectors 2-day

This course builds on geometric dimensioning and tolerancing fundamentals and teaches an introduction of how to inspect GD&T requirements. Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, this course offers an explanation of the geometric symbols, rules, and concepts, the datum system, and how to inspect GD&T requirements using tools from the four categories of inspection tools (CMM; comparison instruments and fixed gages; hand tools and open set up; and production gaging systems). Newly acquired learning is reinforced throughout the class with numerous practice problems.
