We didn't have ER25-chucks/collets when we did that mould, so the whole mould is run with one tool, a flat 6mm endmill. now that we have ER25 tooling(will attach at same z-height every time) it would be smarter to do a rough pass with the endmill and then finish with a ball-end maybe. I don't remember the exact running time, but I do think we made both mould sides in one day, so the machining time for one side must have been 2-3 hours. That's limited mostly by not wanting to loose steps on the stepper driven machine, not by the cutting capacity of the spindle or the tool. With a rigid servo driven machine it could be made much quicker.
