Te re-engineer usually means that a product design, tooling design, structure or whatever (I'll use tooling for this ex.) is not 'up-to-par' or sufficient and must be corrected. This may mean that it must be redesigned (or re-engineered) to conform with code, better engineering practices, or it simply does not fit the bill. Usually re-engineering means to correct an existing tool, structure, etc. However, it could also apply to making duplicate or similar tools that are re-engineered at the time of the build to accomodate needed/wanted changes in the engineering design.

Reverse engineering is used to copy an existing tool exactly. Generally, dimensions and/or scans must be taken of the existing tool and the engineer must build to those numbers. Presumably, someone else designed and/or built the tool trying to be duplicated which is why you'd need to scale the existing one.

Here is an example:

In the 40's the Soviet Union wanted to build a new long-range bomber. They got their hands on a US B-29. They duplicated that plane to the last bolt and bulkhead making no known design changes whatsoever. They Reverse Engineered the entire aircraft, yet they Reengineered not a single part.
