Mechanical Failure Analysis: GD&T and Root Cause

ProoV · Junior Mechanical Engineer · Beginner

About this project

Every inspection said the part was fine, and it still broke. As a junior mechanical engineer you read the fracture and the drawing, run a tolerance stack-up, audit an inspection report, estimate fatigue life, decide what ships, run an FMEA and write an 8D. Demo data, then a real public case.

Mechanical Failure Analysis: GD&T and Root Cause

Just completed

What you'll do

1

Read the part

Read the fracture and the drawing to find out what you're dealing with.

2

Hunt the cause

Run the stack-up, audit the inspection sheet and test the wall on a live test panel.

3

Make the call

The plant manager wants the truck gone. Decide what happens to the batch.

4

Fix it and write the 8D

Rank the fixes with an FMEA and write the report.

5

Read a real public case and hand in

Compare your work with a real failure, explain it in plain words and submit.

What you'll learn

1

Read a drawing and a broken part

Read a fracture surface, find what controls a feature on an engineering drawing, and run a worst-case tolerance stack-up by hand. This is the GD&T and drawing work junior engineers get asked about.

2

Check whether a quality report is telling the truth

Audit an inspection report, catch a wrong datum, flag the walls out of limit and work out Ppk, then estimate stress and fatigue life on a live test panel.

3

Decide and write it up

Hold a bad batch under pressure to ship, rank fixes with an FMEA, and write an 8D report a customer would accept.
