  • Method for machining ceramic matrix composite
    Patent number: 9850175
    Abstract: A method for machining a ceramic matrix composite (CMC), the method enhancing a machining speed for the ceramic matrix composite (CMC), includes: a step of scanning an irradiated portion of a surface of a machining target material by a laser head to irradiate the irradiated portion with laser light from the laser head, and forming a deteriorated layer on the irradiated portion of the surface of the machining target material; and a step of sequentially removing the deteriorated layer by an end mill, the deteriorated layer being formed on the irradiated portion, wherein the deteriorated layer is formed by heating the irradiated portion up to a predetermined temperature by irradiation of continuous oscillation laser light, and by forming a crack by irradiation of pulsed oscillation laser light.
    Type: Grant
    Filed: September 2, 2015
    Date of Patent: December 26, 2017
    Assignee: IHI Corporation
    Inventors: Takahito Araki, Masaharu Yano, Kuniyuki Imanari, Kouta Ishitsu, Takashi Ueda, Akira Hosokawa, Tatsuaki Furumoto
