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.

Systems and methods are provided for generating microscale structures and/or nanoscale structures, surface profiles, and surface chemistries on medical devices. Embodiments disclosed herein utilize exposure of pulsed laser radiation on to a surface of a material by a pulsed laser. The pulsed laser according to embodiments disclosed herein is configured to emit at least one laser pulse toward the surface and thereby modify the profile of the surface in order to selectively promote or inhibit bioactivity and medical functionality of the material. By selectively promoting or inhibiting bioactivity of the material, enhanced biointegration at a cellular level may be achieved. For example, modifying the surface profile and/or surface chemistry of a first substrate material can improve adhesive and/or chemical bonding of the first material to a bioactive second coating material.
