Developing milling for CMC because grinding takes too long.

The article focuses on the challenges and advancements in using ceramic matrix composites (CMC) to improve aircraft engine performance by withstanding higher temperatures. Topics include the potential of silicon carbide (SiC/SiC) CMC for high-temperature resistance and reduced weight, the hurdles in replacing metal turbine blades with CMC due to production and machining difficulties, and the development of new manufacturing technologies.
