Filed:

Nov 1, 2019

Appl. No.:

16/671679

Inventors:

- Peoria IL, US
Christopher S. Meeks - Morton IL, US
Nien L. Lee - Peoria IL, US
Michael S. Radovanovic - Dunlap IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

G01M 15/04

Abstract:

A method and system for grading pistons with deposits is disclosed. In an embodiment, a piston with upon its outer surface deposits is three dimensionally scanned and compared to a reference model to detect the location and geometry of the deposits. The location and geometry of the deposits are recorded and used to grade the pistons. The piston is increased in temperature and thermally scanned. The deposits are identified based on the temperature differences measured with respect to the temperature of the outer surface of the piston. Deposit characteristics can be generated from the identified locations of deposits and the magnitude of temperature difference with respect to the outer surface. The deposit characteristics are recorded and used to grade the pistons.
