Abstract
A method of machining includes removing material from a target region of a ceramic component to form a blind opening in the ceramic component via removing a bulk of the material by a laser machining operation and then removing a remainder of the material by a mechanical machining operation.
Claims7
A method of machining comprising:
- removing material from a target region of a ceramic component to form a blind opening in the ceramic component by:
- (i) removing a bulk of the material by a water-guided laser machining operation, and
- (ii) after (i), removing a remainder of the material by a mechanical machining operation.
A method of machining comprising:
- removing material from a target region of a ceramic component to form a blind opening in the ceramic component by:
- (i) removing a bulk of the material by a laser machining operation, and
- (ii) after (i), removing a remainder of the material by a mechanical machining operation, wherein the laser machining operation in (i) removes at least 75% of the material.
