Title:
MACHINING TOOL AND METHOD FOR ABRADABLE COATING PATTERN
Document Type and Number:
Japanese Patent JP2015021501
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a machining tool and machining method for creating a pattern in abradable coatings placed at surfaces of components of gas turbine engines, radial flow compressors and radial turbines, including micro-turbines and turbo-chargers, that are exposed to high temperature environments.SOLUTION: A method for forming a pattern in an abradable coating 130 includes the step of machining a groove in the abradable coating with a machining tool. The machining tool is configured to machine a top surface 132, a side surface 134 and a bottom surface 136 of the groove simultaneously. A repeating step repeats the machining step until a desired number of grooves are obtained in the abradable coating.
