Mechanical roughening profile modification tool

Abstract

An interpolated roughening cutting tool includes a body having at least first and second cutting elements coupled thereto. The first cutting element includes rectangular cutting teeth. The second cutting element includes non-rectangular cutting teeth. The first and second cutting elements are configured to create grooves in a surface that have a top portion with blunt edge surfaces.

What is claimed is: 
     
         1 . An interpolated roughening cutting tool, comprising:
 a body having at least first and second cutting elements coupled thereto;   the first cutting element including rectangular cutting teeth; and   the second cutting element including non-rectangular cutting teeth,   the first and second cutting elements are configured to create grooves in a surface that have a top portion with blunt edge surfaces.   
     
     
         2 . The tool of  claim 1 , wherein the first and second cutting elements are configured to create grooves with chamfered edges having a chamfer angle and a chamfer length. 
     
     
         3 . The tool of  claim 2 , wherein the chamfer angle is 20 to 70 degrees. 
     
     
         4 . The tool of  claim 2 , wherein the chamfer length is at most ⅓ of a maximum groove peak width. 
     
     
         5 . The tool of  claim 1 , wherein the rectangular cutting teeth are configured to create groove sides that are substantially perpendicular to the surface. 
     
     
         6 . The tool of  claim 1 , further comprising third, fourth, fifth, and sixth cutting elements. 
     
     
         7 . The tool of  claim 6 , wherein the third cutting element includes rectangular cutting teeth offset from the cutting teeth of the first cutting element. 
     
     
         8 . The tool of  claim 6 , wherein the fourth cutting element includes non-rectangular cutting teeth offset from the cutting teeth of the second cutting element. 
     
     
         9 . The tool of  claim 6 , wherein the fifth and sixth cutting elements each include a substantially flat cutting surface. 
     
     
         10 . The tool of  claim 6 , wherein the first, second, third, fourth, fifth, and sixth cutting elements are equally spaced around the body. 
     
     
         11 . The tool of  claim 6 , wherein the first and third cutting elements are adjacent to each other, and the second and fourth cutting elements are adjacent to each other. 
     
     
         12 . An interpolated roughening cutting tool, comprising:
 a body having at least first and second cutting elements coupled thereto;   the first cutting element including rectangular cutting teeth; and   the second cutting element including curved cutting teeth having a peak and two concave sides extending therefrom,   the rectangular cutting teeth are configured to create groove sides that are substantially perpendicular to a surface, and the curved cutting teeth are configured to create rounded groove edges.   
     
     
         13 . The tool of  claim 12 , further comprising third, fourth, fifth, and sixth cutting elements. 
     
     
         14 . The tool of  claim 13 , wherein the third cutting element includes rectangular cutting teeth offset from the cutting teeth of the first cutting element. 
     
     
         15 . The tool of  claim 13 , wherein the fourth cutting element includes non-rectangular cutting teeth offset from the cutting teeth of the second cutting element. 
     
     
         16 . The tool of  claim 13 , wherein the first and third cutting elements are adjacent to each other, and the second and fourth cutting elements are adjacent to each other. 
     
     
         17 . An interpolated roughening cutting tool, comprising:
 a body having at least first and second cutting elements coupled thereto;   the first cutting element including rectangular cutting teeth; and   the second cutting element including triangular cutting teeth,   the rectangular cutting teeth are configured to create groove sides that are substantially perpendicular to a surface, and the triangular cutting teeth are configured to create chamfered edges.   
     
     
         18 . The tool of  claim 17 , wherein the first and second cutting elements are configured to create grooves with chamfered edges having a chamfer angle and a chamfer length. 
     
     
         19 . The tool of  claim 18 , wherein the chamfer angle is 20 to 70 degrees. 
     
     
         20 . The tool of  claim 18 , wherein the chamfer length is at most ⅓ of a maximum groove peak width.
