Eldar Gerfanov says: “There probably should be a “Max cutting force” value in the machine profile. I will add in the future updates [to HSMAdvisor].” (see the pinned comments). Most/all CNC gantry routers are limited by rigidity (hence cutting force) rather than spindle power. If he follows through with that, HSMAdvisor would be much more useful. Maybe some added encouragement would help?
But, it would be really good to be able to estimate cutting forces from measurements of spindle power and/or current.
