Method To Measure Tool Wear From Process Model Parameters

View page
US Patent:
20080161959, Jul 3, 2008
Filed:
Dec 3, 2007
Appl. No.:
11/998884
Inventors:
Robert B. Jerard - Durham NH, US
Donald Esterling - Carrboro NC, US
Barry K. Fussell - Durham NH, US
Min Xu - Charlotte NC, US
Chad Schuyler - Georgetown MA, US
International Classification:
G06F 17/00
US Classification:
700110
Abstract:
A system and method for monitoring tool wear in CNC machining operations by monitoring spindle power and extracting instantaneous cutting geometry. The method is based on a physics-based two parameter process model and measuring at two different cutting conditions. The process model parameters are measured with easily accessible spindle power. In contrast to spindle power alone which is influenced by many factors, most especially by variable cutting conditions and by the tool condition, the process model parameters are independent of the geometrically variable cutting conditions and provide a simple and direct measure of tool wear. The two process model parameters change differently depending on the mechanism of the tool wear, specifically flank wear versus cutting edge degradation. This provides a diagnostic for tool wear.

US Patent:
20090234490, Sep 17, 2009
Filed:
Mar 17, 2009
Appl. No.:
12/405513
Inventors:
Christopher A. Suprock - Exeter NH, US
Jeff Nichols - Dover NH, US
Robert Jerard - Durham NH, US
Barry Fussell - Durham NH, US
International Classification:
G06F 19/00
B23B 31/00
US Classification:
700159, 408 16, 408116, 408238
Abstract:
A smart tool holder is for use with a machine tool platform. The smart tool holder includes a body having a first end and an opposite second end, a processor disposed with the body, and a transceiver disposed with the body and in communication with the processor. The transceiver is structured to communicate with an external receiving device. The first end of the body is structured to be coupled to the machine tool platform and the opposite second end is structured to be selectively coupled to a cutting assembly having a number of sensors. The processor is structured to communicate with the number of sensors when the cutting assembly is coupled to the body. The processor may perform data analysis tasks using model based data analysis, digital filtering, and other techniques. The smart tool holder may suggest changes to the machining process based on two-way communication with a machine tool controller through a receiver or interface device.
