Cutting tools and machining methods using cutting tools

Abstract

Cutting tools and machining methods using cutting tools are disclosed. An example cutting tool comprises a shank and a head on the shank, the head comprising a diamond abrasive-coated cutting surface, the cutting head having grooves interrupting the cutting surface and extending from the cutting surface toward an axis of rotation of the head, the cutting surface having a substantially constant radius.

What is claimed is: 
     
         1 . A cutting tool, comprising:
 a shank; and   a head on the shank, the head comprising a diamond abrasive-coated cutting surface, the head having grooves interrupting the cutting surface and extending from the cutting surface toward an axis of rotation of the head, the cutting surface having a substantially constant radius.   
     
     
         2 . A cutting tool as defined in  claim 1 , wherein the cutting surface is cylindrical, the head further comprises a planar end cutting surface, and an edge of the head between the cutting surface and the end cutting surface is radiused. 
     
     
         3 . A cutting tool as defined in  claim 2 , wherein the grooves extend from the planar end cutting surface to an upper edge of the cutting surface. 
     
     
         4 . A cutting tool as defined in  claim 1 , wherein the shank is to be operatively coupled to a Computer Numerical Control (CNC) machine. 
     
     
         5 . A cutting tool as defined in  claim 1 , wherein the head is hemispherically shaped. 
     
     
         6 . A cutting tool as defined in  claim 1 , wherein the grooves are helically shaped. 
     
     
         7 . A cutting tool as defined in  claim 1 , wherein the cutting surface has the substantially constant radius in an axial direction of the head. 
     
     
         8 . A cutting tool as defined in  claim 1 , wherein the cutting tool is to perform cutting with the diamond abrasive-coated cutting surface. 
     
     
         9 . A method of applying a diamond abrasive cutting tool configuration to machining of a filler from a non-metallic composite material, comprising:
 engaging a filler material sheet with a cutting tool, the cutting tool including a shank and a head on the shank, the head comprising a diamond abrasive-coated cutting surface, the head having grooves interrupting the cutting surface and extending from the cutting surface toward an axis of rotation of the head, the cutting surface having a substantially constant radius; and   machining a filler from the filler material sheet using the cutting tool.   
     
     
         10 . A method as defined in  claim 9 , wherein engaging the filler material sheet comprises engaging the filler material sheet with a cylindrical cutting surface, the head further comprises a planar end cutting surface, and an edge of the head between the cutting surface and the end cutting surface is radiused. 
     
     
         11 . A method as defined in  claim 10 , wherein the grooves extend from the planar end cutting surface to an upper edge of the cutting surface. 
     
     
         12 . A method as defined in  claim 9 , wherein the shank is to be operatively coupled to a Computer Numerical Control (CNC) machine. 
     
     
         13 . A method as defined in  claim 9 , wherein the head is hemispherically shaped. 
     
     
         14 . A method as defined in  claim 9 , wherein the grooves are helically shaped. 
     
     
         15 . A method as defined in  claim 9 , wherein the cutting surface has the substantially constant radius in an axial direction of the head. 
     
     
         16 . A method as defined in  claim 9 , wherein the cutting tool is to perform cutting with the diamond abrasive-coated cutting surface.
