Question:

Why is it important to perform incremental testing for complex assemblies?

Erik W.
Answer:

Test failures result not only from inadequate designs, but also from material flaws and process defects introduced in the manufacturing phase. Incrememental testing makes for easier isolation of root cause, and also corrects problems prior to additional time and financial investment in a complex assembly.

Manufacturing Engineering

Question:

List some reasons why organizations benefit from a producibility review of new designs.

Erik W.
Answer:

1. A manufacturing engineering (ME) specializing in produiblity can often recommend consistency with radius/hole callouts, reducing tooling and manufacturing time. 2. An ME is an excellent point of contact for documenting "lessons learned" related to prior manufacturing issues. 3. An ME will optimize the manufacturing flow and sequence prior to design completion

Question:

Cite examples for why additive manufacturing (ie 3D printing) is a technological disruptor in Aerospace Engineering

Erik W.
Answer:

1. Additive Manufacturing (AM) creates no scrap material, and traditional machined alloys in the aerospace arena are very expensive. 2. Part counts can be significantly reduced, and can design complexity. 3. AM parts, after simple post-processing, have desirable structural properties
