    Abstract: A screw type shaving cutter and a method of producing the same. A large number of cutting edges are formed on the flanks of the thread of the cutter. Each cutting edge is inclined along a curve or a straight line in the trailing direction as viewed in the direction of rotation of the cutter in use. This shaving cutter is produced by forming a screw body by cutting a metal blank into a form of a screw, and forming a number of cutting edges on the flanks of the thread of the screw body by reciprocatingly moving a cutting tool on the flanks of the thread, while rotating the screw body continuously in one direction.

    Abstract: A shaving cutter includes cutting teeth each being formed with lands and grooves in the opposite faces thereof; the lands providing cutting edges for a shaving operation and including two types of lands. One type of land being cut off substantially in an addendum region thereof and the other being cut off substantially in a dedendum region thereof. The cut off portion of the land being so arranged that it does not engage in the shaving operation, whereby the cutting face area is reduced so as to increase the depth of the cut, thus obtaining various advantages such as reduction of frictional distance, wear of the cutting edge, improved precision of shaving, shortening of the period of the cutting process, and the like.

    Abstract: A gearlike tool adapted for working a gear by rolling. The tooth surfaces of said tool are provided with grooves for forming cutting edges. Said grooves are offset axially along a section of a helix, which section when axially measured comprises a groove pitch or multiple thereof plus or minus a selected amount and is equal to the amount of groove offset from one tooth to the next of the workpiece multiplied by the number of such teeth. Further, said length is of a value other than that of the selected amount and the entire number of teeth of the tool is an integral multiple of the groove pitch divided by the groove offsets from one tooth to the next.

    Abstract: A tool for the precision working of gears by chip removal therefrom such as in gear shaving and of the type wherein the flanks of the tool teeth comprise a plurality of alternate grooves and lands having a novel cutting edge construction between the surfaces of said lands and the walls of the adjacent grooves and between the tip surfaces of the tool teeth and the land adjacent thereto. Particularly said walls and the tip surfaces adjacent thereto are provided with cutting edges for plunge shaving wherein with a given relief angle the rake angle may be positive, negative or zero.
