<p>A milling machine cutter tool structured and oriented to perform complex three dimensiomal contour machining operations and provides for the cutting edges of the cutter to engage the workpiece in the same direction as the feed direction, thereby resulting in maximal cutting efficiency. The cutting tool is composed of a sleeve rotatably mounted to the milling machine 102, a quill 116 axially movable in the sleeve 114, a position drive for selectively moving the quill 116 relative to the sleeve 114, a drive shaft 140 rotatably supported in the quill 116 and connected at a rear end thereof to a cutter drive, a cutter head 146 connected to the opposite forward end of the quill, a worm gear 160 set mounted in the cutter head 146 connecting gearably to the drive shaft 140, a cutter shaft 152 mounted in the cutter head 146 transversely in relation to the drive shaft 140 and gearably connected to the worm gear 160 set, and a side cutter 118 connected to the cutter shaft 152, the side cutter 118 supporting teeth 162 extending forwardly of the cutting head 146. In one preferred embodiment, the drive shaft 140 is powered by a self-contained drive motor connected to the quill 116. In a second preferred embodiment, the drive shaft 140 is powered by the spindle drive system of the milling machine. <IMAGE></p> |
