Abstract:
A line transfer system for machining a workpiece, comprising:a transmission arbor mounted within a housing, the transmission arbor and housing sharing a common central axis; at least one contour machining head for mounting to the housing, comprising: a bit tool for machining the workpiece; a slidable carriage for mounting the bit tool; a linkage for transferring 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; and a counterweight linked to the transmission arbor to dynamically counterbalance the radial movement of the slidable carriage and bit tool; a pilot to align the contour machining head with the workpiece; a driving system mounted to the housing, the driving system 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; and a system controller configured to control the force applied by the driving system and the movement of the bit tool.
