1. A method of reprofiling a wheel set of a railway vehicle comprising:
disposing the wheel set on one or more rollers, the rollers being supported on a milling station;
determining a center of rotation of a wheel on the wheel set;
determining a desired constant distance between a cutting tool and the center of rotation of the wheel;
rotating the wheel on the one or more rollers and allowing the center of rotation of the wheel to move relative to the one or more rollers while rotating the wheel;
activating the cutting tool to mill a profile on the wheel while rotating the wheel and preventing radial movement of the rollers relative to the milling station while the cutting tool is activated; and
during the activating step, moving the cutting tool towards the constant distance between the cutting tool and the center of rotation of the wheel while the cutting tool is activated and while preventing radial movement of the rollers to maintain the rollers in a fixed position relative to the milling station while allowing the rollers to rotate.
