U mentioned this before, and so did DAVE as well, about NEGATIVE / POSITIVE Inserts. A little befuddling to rookies.
We did try to grasp the the reference to it on looking up Walter's Catalogue which showed a certain difference in ANGLES of each. We assume this to be the Insert RAKE as presented to the workpiece ???
However, is there a quicker way of making us understand, maybe in lay terms, what effect each has in a cutting action and why one would be better, or worse, than the other. We note U mention here, and in our discussions as well, that the size of a machine's Motor capacity does have to be taken into consideration, or has a lot to do with the final finish with that specific type of Insert.
Seeing that we are neither adept at shaping nor sharpening HSS cutters and have gone the direct route of less time consuming Insert usage, it would be good to get a proper clarification on this for future choice of Inserts and Toolholders. Guess others out there may benefit from Your discourse as well.
As always, we sincerely appreciate the magnanimous sharing of Your tremendous expertise.
LORD BLESS
