Abstract
A line transfer system with a contour machining head. The system includes a transmission arbor, a housing, a contour machining head, a driving system, and a system controller. The transmission arbor mounts within the housing, with the transmission arbor and housing sharing a common central axis. At least one contour machining head mounts to the housing. The contour machining head includes a bit tool, a slidable carriage, a linkage, a counterweight, and a pilot. The bit tool is configured for machining the workpiece, and mounts to the slidable carriage. The linkage connects to the carriage and transfers a force from the transmission arbor to the slidable carriage resulting in an independent radial movement of the bit tool with respect to the central axis. The counterweight links to the transmission arbor to dynamically counterbalance the radial movement of the slidable carriage and bit tool. Finally, the pilot connects to the contour machining head and aligns the contour machining head with the workpiece. The driving system mounts to the housing, and is configured for providing a force to the transmission arbor; providing a force to the contour machining head resulting in an independent axial movement of the bit tool with respect to the central axis; and providing a force to the contour machining head resulting in an independent rotational movement of the bit tool with respect to the central axis. The system controller is configured to control the force applied by the driving system and the movement of the bit tool.
