Method and apparatus for a cutting tool

Abstract

A method of making a cutting tool comprises providing a lever with a jaw having a cutting edge and a body arranged such that the cutting edge is offset from the body; providing a rotary cutting tool with an edge profile that may be complex and/or non-planar to form a complementary edge profile geometry on the cutting edge by moving the edge profile geometry of the rotary cutting tool along the length of the cutting edge.

1 . A method of making a cutting tool comprising:
 providing a lever comprising a jaw having a cutting edge and a body arranged such that the cutting edge is offset from the body;   providing a rotary cutting tool with an edge profile geometry;   forming a complementary edge profile geometry on the cutting edge by moving the edge profile geometry of the rotary cutting tool along the length of the cutting edge.   
     
     
         2 . The method of  claim 1  wherein the step of forming is done when the cutting edge is in a soft state. 
     
     
         3 . The method of  claim 1  wherein the step of forming is done when the cutting edge is in a hardened metal. 
     
     
         4 . The method of  claim 1  wherein the lever arm of the tool is fixtured in a predetermined position. 
     
     
         5 . The method of  claim 1  where the rotary cutting tool is fed in a straight path along the cutting edge. 
     
     
         6 . The method of  claim 1  where the rotary cutting tool traverses the entire cutting edge. 
     
     
         7 . The method of  claim 1  where the rotary cutting tool traverses the cutting edge without contacting the body. 
     
     
         8 . The method of  claim 1  further comprising providing a plurality of levers each having a cutting edge, fixturing the plurality of levers such that each cutting edge of the plurality of levers are aligned, moving the rotary cutting tool along a linear path along the cutting edges. 
     
     
         9 . The method of  claim 1  wherein the rotary cutting tool is a grinding wheel. 
     
     
         10 . The method of  claim 1  wherein the rotary cutting tool is a form cutter. 
     
     
         12 . A method of making a cutting tool comprising:
 providing a lever comprising a jaw having a cutting edge and a body arranged such that the cutting edge is offset from the body;   providing a rotary cutting tool with a first edge profile and a second edge profile;   forming a first portion of complementary edge profile geometry on the cutting edge by moving the first edge profile of the rotary cutting tool along the length of a first side of the cutting edge and forming a second portion of complementary edge profile geometry on the cutting edge by moving the second edge profile of the rotary cutting tool along the length of a second side of the cutting edge.   
     
     
         13 . The method of  claim 12  wherein the step of forming is done when the cutting edge is in a soft state. 
     
     
         14 . The method of  claim 12  wherein the step of forming is done when the cutting edge is in a hardened metal. 
     
     
         15 . The method of  claim 12  wherein the lever arm of the tool is fixtured in a predetermined position. 
     
     
         16 . The method of  claim 12  where the rotary cutting tool is fed in a straight path along the cutting edge. 
     
     
         17 . The method of  claim 12  where the rotary cutting tool traverses the entire cutting edge. 
     
     
         18 . The method of  claim 12  where the rotary cutting tool traverses the cutting edge without contacting the body. 
     
     
         19 . The method of  claim 12  further comprising providing a plurality of levers each having a cutting edge, fixturing the plurality of levers such that each cutting edge of the plurality of levers are aligned, moving the rotary cutting tool along a linear path along the cutting edges. 
     
     
         20 . The method of  claim 1  wherein the rotary cutting tool is a grinding wheel or a form cutter.
