Ceramic matrix composites have the characteristics of high hardness

high strength

anisotropy and heterogeneity

which lead to severe tool wear

poor processing quality and low processing efficiency during processing. The milling process of the laser ablation treated samples proved that almost no force and heat are generated when milling the powdery ablation products. Using finite element simulation and unidirectional ultrasonic vibration-assisted milling

it is found that the ultrasonic vibration-assisted milling process can achieve low-damage machining of ceramic matrix composites without reducing the processing efficiency. A combined processing technology of laser ablation and ultrasonic vibration assisted milling is proposed. Based on multi-dimensional indicators such as machining quality

machining efficiency

and tool cost

the milling machining strategy is comprehensively evaluated. The strategy of laser ablation+ultrasonic vibration assisted milling can obtain a better quality machined surface

and at the same time

the processing time is less

and the tool cost is low. In general

it is a process scheme that can realize high-efficiency and lowdamage milling of ceramic matrix composites
