For any given tool path it would be super handy to have an idea about the Net Power / Torque required. Simply by having a list of materials (e.g. EW-6060) or by manually entering the Specific Cutting Force ( x N/mm^2).
This would greatly help to utilize all the available power for material removing. Also would it help to avoid having tool path that would be to "hard" for the spindle and eventually crash the tool or the machine.
Having a numerical and/or graphical read out of the power required for a tool path would perfectly fit in the Feed & Speed menu.
