Abstract
A milling apparatus is provided for cutting desired contours into a workpiece. The apparatus comprises a head that moves relative to a workpiece in a direction of cut. Spindles are supported on the head for rotation about parallel spaced-apart spindle z axes and comprise respective rotary cutters adapted for use in machining operations. A rotary head positioner is configured to be operatively connected between the head and a milling machine and to rotate the head about a head axis. A stagger controller is connected to the rotary head positioner and is configured to provide a desired swath of a cut to be formed in a workpiece by rotating the head to set a corresponding spindle stagger angle value.
