Versatile face-mill cutting tool apparatus particularly useful in the manufacture of relatively large gears having diameters of 2 to 6 feet (0.6 to 2 meters). A single cutter body can be used in combination with one set of cutter blades to satisfy a wide variety of tool parameters: Blades and blade holders can be readily reversed as required for clockwise or counter-clockwise tool rotation. The angle of the cutting edge of each blade can be adjusted through a fairly wide range of settings as required by the design of the tooth slot being cut. Fine radial adjustments of cutting blades can be made for cutter truing and gear tooth development without shims. This latter feature is accomplished by moving the blade holders along respective straight line paths which, when extended, form an equilateral convex polygon about the center of rotation of the cutter body. |
