Filed:

Apr 28, 2010

Appl. No.:

13/266550

Inventors:

James Rhett Mayor - Stockbridge GA, US
Angela Ann Sodemann - Smyrna GA, US
Stephen Andrew Semidey - Jonesboro GA, US

Assignee:

Georgia Tech Research Corporation - Atlanta GA

International Classification:

B23Q 17/22
B23C 9/00

US Classification:

409132, 409193

Abstract:

A relatively inexpensive and accurate method for micro scale tool touch-off and remaining tool life estimation using advanced methods of tool-workpiece conductivity monitoring. Part registration is based on a conductive circuit detection technique that utilizes an analog DC voltage. A tool life estimation system is provided, and accomplished through the combined application of hardware signal filtering and advanced signal processing techniques implemented on a digital signal processing unit.
