101 Method for generating gear-shaped precision-working tool and gear-shaped tool JP11282993 1993-05-14 JPH0631533A 1994-02-08 HERUBERUTO ROOSU; MANFUREETO ERUHARUTO
PURPOSE: To execute optimum working on all occasions in the generated condition extending over the life of a precision-working tool by changing a pitch cylinder helix angle, a transverse module, and a base circle diameter, so as to change the originally existed profile shift only extremely little or not to change. CONSTITUTION: The original number of teeth. (z) and the original normal module mN are maintained, the pitch cylinder helix angle β, the transverse module MS, and the base circle diameter dg are changed, and in addition the originally existed profile shift is perfectly or almost not changed. Hereby when the afterward generated tool is used, machine setting must be changed, but invariably maintained good machining result can be obtained extending over the entire lifetime of the tool.

103 Tool provided with hand grip JP15303084 1984-07-25 JPS6133818A 1986-02-17 KIGAMI YUKIO
PURPOSE:To improve both efficiency of work and safety thereof by providing a hand grip having no cutting edge, projectingly in axial direction of the tool main body having cutting edges along its outer periphery. CONSTITUTION:Cutting edges 2 are formed in the central area of the outer periphery of a tool main body 1 and a hand grip 4 having no cutting edge is projected in the axial direction at the rear end of the outer periphery thereof. Owing to the above hand grip 4 having no cutting edge and formed in the axial direction, even bare-handed handling of a tool will not injure the operator's hand in a work for removing the tool etc. thus ensuring safety in the work and improving the efficiency thereof.

The ends of gear teeth are chamfered using an arcuate motion cutter having a complex cross sectional shape. In an improvement of the prior trial and error techniques, the cutter shape is made correctly the first time using an algorithm which includes determining certain s-dimensions produced on a chamfer by a set of tool dimensions; comparing these to the desired maximum, minimum and nominal chamfer widths, and; then iteratively optimizing the set of tool dimensions to minimize the differences.
