Forgive my stupidity, by why do you need all that z-movement for a wind turbine blade? If you're thinking of cutting them vertically 'on the hub' so to speak I think you run the risk of, as a minimum, the blade deflecting, or worse snapping off... anything that high a length to width ratio probably needs milling horizontally and adequately supported... or have i got the wrong end of the stick (or should that be blade?) :lol:
