when to use "undergo"?

hi there

I'm not sure how to use the word "undergo" as a verb, particularly in scientific writing.

I've seen a lot of usage such as "undergoing oscillation", "undergoing compression", "undergoing the motion".  The question is, why not use "oscillating", "compressing/compressed/being compressed" directly?  Does undergoing have more than "be subject to" meaning in such condition?

You would say "the spring undergoing ocsillation" but not "the projector undergoing display(ing)", wouldn't you?
Or "the layer undergoing compression" = "the layer being compressed"?
You would say "the company undergoes a massive restructuring" but not "the company restructures massively"??

Thanks in advance

Alright, so it shouldn't deviate from the meaning, but just a way it is written.  I was afraid it would mean differently, even if slightly, such as sounding passive or something.
