Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for machining a ceramic matrix composite, the method comprising: a step of scanning an irradiated portion of a surface of a machining target material by laser light to irradiate the irradiated portion with the laser light, and forming a deteriorated layer on the irradiated portion of the surface of the machining target material; and a step of removing the deteriorated layer by a machining tool, 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. 2. The method according to claim 1 , wherein, in the step of removing the deteriorated layer, the deteriorated layer formed on the irradiated portion is sequentially removed by the machining tool, which machining tool follows the irradiated portion apart from the irradiated portion by a predetermined distance. 3. The method according to claim 2 , wherein the machining tool is an end mill. 4. The method according to claim 1 , wherein, in the step of forming a deteriorated layer, the deteriorated layer is formed in a predetermined region of the surface of the machining target material, and in the step of removing the deteriorated layer, the deteriorated layer is removed after the deteriorated layer is formed in the predetermined region.
