METHOD AND APPARATUS FOR A CUTTING TOOL
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.
