Publication number: 20230259094Abstract: A method for calibrating a machining system includes providing the machining system which includes a base, a cantilevered arm, and a rotary table positioned at the second arm end of the cantilevered arm. The rotary table is rotatable relative to the cantilevered arm about a first axis. The first axis has a first unloaded position and a first unloaded orientation with the machining system in an unloaded condition. The method further includes installing a measurement artifact on the rotary table, measuring a first position of the measurement artifact, and installing a load on the rotary table. The first axis has a first loaded position and a first loaded orientation with the machining system in a loaded condition. The method further includes measuring a second position of the measurement artifact and determining a positional deviation of the second position from the first position.Type: ApplicationFiled: February 11, 2022Publication date: August 17, 2023Inventors: Visal Ing, Rachid Guiassa, Joel Jean, Ghislain Hardy, Faical Ghezala

Patent number: 11208891Abstract: Methods of repairing a part having a firtree-shaped feature requiring rework are disclosed. An embodiment of the method includes receiving the part having the firtree-shaped feature requiring rework. The part is installed in a machine configured for wire electrical discharge machining (EDM). A location of the firtree-shaped feature relative to a datum of the machine is then determined. Wire EDM is performed on the firtree-shaped feature.Type: GrantFiled: September 20, 2019Date of Patent: December 28, 2021Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Visal Ing, Ghislain Hardy, Joel Jean
