Maximum work capacities are dependent on a lot of variables that cannot be controlled by the machine
manufacturer. Each one of the following will have an impact on the above numbers: speeds, feeds,
cutter, cutter sharpness, material, setup, coolant and machine adjustments. The numbers above
assume all conditions are optimal and may be higher or lower depending on material composition.
