Unrelated, but I used to get a fries with salad on top at Uni on the way home from my part time job and I was so happy to have like 10 series of "How it's Made" as I munched. I am not talking about Skiving heatsinks specifically, but clearly this is a needed tool, so how did it come to be? What is the job title? Someone in this case, needed heatsinks quick, so how did it go from someone needing lots of heatsinks to an industrial tool? Was there a guy shaving copper manually, and some (job title) came to the factory and suggested creating a moving table with a blade to optimise the creation?

Not in metal manufacturing, but semi-knowledgeable with some professional interest. Metal is machined by cutting tools. The two machine tools that I'd guess are most closely related to this are the shaper (which is totally unrelated to a wood shaper or the confusingly named Shaper Origin) and planer (which is almost completely unrelated to the wood planer, except in rough concept). Both work by dragging a cutting tool against a workpiece and removing a chip. Both are reciprocal and step over between strokes to cover a wider workpiece surface than the width of the cutting tool. You'd be very unlikely to see either taking a chip this wide in, say, steel because you'd need an immense amount of power and rigidity in the machine to control the cut. I don't think either typically does any movement in the z axis through their working stroke, and I don't think the stroke typically changes it's starting point along the axis of the stroke. Nonetheless, the very basic motion and chip formation is close enough that one might reasonably come up with the skiving motion from either of them if it didn't already exist. Skiving, incidentally is also a term in leatherworking where, as I understand it, it's an operation that reduces the thickness of a piece of leather by slicing action. I don't know if tapering the end of a leather piece is also known as skiving, or if there's a more specific term for making a slicing cut through the thickness at an angle.
