Absolute Diameter Measurement Arm
US Patent:
8219353, Jul 10, 2012
Filed:
Jan 28, 2010
Appl. No.:
12/695304
Inventors:
Robert M. Lee - Magnolia MA, US
Robert E. Parsons - Gloucester MA, US
Robert E. Parsons - Gloucester MA, US
Assignee:
Axiam, Inc. - Gloucester MA
International Classification:
G01B 5/08
US Classification:
702157, 702127, 702 85, 702 99, 702136, 73 179, 73 181, 33502
Abstract:
A measurement apparatus calibrated to measure an absolute diameter of a part in a shop floor environment. The measurement apparatus includes a calibration that includes compensation factors for thermal expansion, shifting of measurement parts (arm, support tower, and related laser), and variances of these parts. The resulting measurements report an absolute diameter of a part to a higher degree of accuracy than previously possible. Also, the calculated compensation factor eliminate the need for an isolated, climate-controlled measurement room.
Method And Apparatus For Geometric Rotor Stacking And Balancing
US Patent:
7877223, Jan 25, 2011
Filed:
May 22, 2009
Appl. No.:
12/470998
Inventors:
Robert M. Lee - Magnolia MA, US
Robert E. Parsons - Gloucester MA, US
Robert E. Parsons - Gloucester MA, US
Assignee:
Axiam, Inc. - Gloucester MA
International Classification:
G01P 3/00, G06F 15/00
US Classification:
702150, 702147
Abstract:
A computer method or corresponding system for optimally balancing a rotor assembly. The computer system defines a theoretical centerline based on a mathematical model of the rotor assembly. For each disc or component of the rotor assembly, the invention system calculates rotor blade or bolt and washer distribution, based on calculated centerline deviations and angular locations of the discs and effective weights of rotor blade or bolt-and-washer sets. The rotor blade or bolt-and-washer distribution provides locations for placement of the rotor blades or bolts-and-washers so as to offset the centerline deviations and thus correct imbalance of the rotor assembly.
