As shown in the equations at the bottom of the SFPF worksheets, cutting powers and forces are determined by material removal rates, not chip-loads. Excessively high chip-loads waste cutting power and force by generating excessive heat. The cutter, workpiece, and chip all “feel” that heat and are negatively impacted by it.
We should probably move subsequent (and past?) subject area posts to this new thread to keep from de-railing the other posts that have been used. Sorry OPs!
