I knew you'd ask that. It was between 20 and 25 years ago; the story was about using wirecut EDM to shape sinterred diamond compacts on the cutters used in both metalworking (a minor use) and woodworking (the major use), particularly on commercial spindle-shapers and routers. The discussion about saw blades was peripheral to the subject, because EDM isn't used to shape the edges of those.
All I can recall is this: In production rip-sawing, the issue is how the cutter *exits* the cut, rather than how it enters. Apparently -- and this is from memory -- saw blades used in commercial ripping just barely extend through the top of the cut, so the re-entry isn't an issue. On the top side of the work, it's almost the same whether you consider it climb- or conventional-cutting. But it makes a big difference when the blade finally leaves the bottom of the cut. If it's cutting when it comes out of the workpiece, it's going to tear the edges of the cut, as any hobbyist woodworker knows from conventional work with a table saw. In the discussion, running the blade in the reverse direction of what most of us condider the "conventional" one, in which the blade exits the work "not cutting," was what they were calling "climb cutting," and apparently that's the preferred mode for production. It requires friction drive and hold-down rollers; the work is fed under power.
BTW, some commercial saws operate upside-down, with the blade(s) above the work, so you might have to reverse "up" and "down" from this discussion. That may just be for multi-blade ripping of lumber; I've never actually seen one of those saws.
I never got involved in studying production woodworking except for that single application, and it was because I covered tooling for a couple of metalworking magazines and I had a client who made special wire EDMs for that work, when I wasn't a staff editor.
Sorry I can't refer you to my article. That old stuff isn't archived online and I wrote over 350 articles about metalworking and tooling, so I don't remember where it ran.
A good question; I don't know about those saws. I hesitated to jump in here at all, except to point out that there is something that is, or was, called "climb cutting" in production sawing, and that it's similar to what we mean by the term in metalworking, with milling cutters.
I will now go back to my nap.
