US Patent:

7140812, Nov 28, 2006

Filed:

May 29, 2002

Appl. No.:

10/159925

Inventors:

William J. Bryan - Mahtomedi MN, US
Nelson D. Sewall - Forest Lake MN, US
Jeffrey E. Clements - New Richmond WI, US

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

B23B 27/20

US Classification:

407119, 407113, 29557

Abstract:

In one embodiment, a tool used for creating grooves in a microreplication tool is described. The tool includes a mounting structure and a multi-tipped diamond mounted in the mounting structure. The different tips of the diamond may correspond to different grooves to be created in the microreplication tool. In this manner, the creation of a microreplication tool using a diamond can be simplified and/or improved.

Abstract:

In one embodiment, a cutting tool assembly used for creating grooves in a microreplication tool is described. The cutting tool assembly includes a mounting structure and multiple diamonds mounted in the mounting structure. For example, first and second tool shanks having first and second diamond tips can be positioned in the mounting structure such that a cutting location of a diamond cutting tip of the first tool shank is a defined distance from a cutting location of a diamond cutting tip of the second tool shank. The defined distance may correspond to an integer number of pitch spacings, and may be accurate to within a tolerance of less than approximately 10 microns.
