The correct term is “SEGMENTED WOODTURNING”

In 40 years of professional and hobby woodworking this is the first time I heard it referred to as “segmentation”! Hobby forums seem to try to relabel things. One forum a few years ago tried renaming a standard veneering term bookmatching with the term “butterfly”. I think if folks read more text books there would be less confusion over the proper terminology. It’s just makes it easier to talk about things. Personally I thing it’s best to go to other sources than the forum where a definition question comes up.
-- Few folks really know how to maximize the potential of their tools!
