    (Objectives: Aiming at the problem of grinding stability in the processing of CFRP circular cell honeycomb. )

    Methods:
    taking a single thin-walled CFRP circular cell as the research object, the end face grinding experiment was carried out by defining the exit angle and interaction angle of grinding considering its structural characteristics. Based on the relationship between interaction angle of grinding and exit angle, the effects of grinding speed, feed rate and grinding depth on grinding stability were further analyzed.

    Results:
    The results show that the exit angle is the main factor affecting the grinding stability. When the exit angle is from 60° to 90°, the interaction angle of grinding is small and the grinding stability is poor. With the increase of grinding speed, the interaction angle of grinding increases gradually, and the grinding stability increases. With the increase of feed rate, the interaction angle of grinding has no obvious change, and the grinding stability is almost unchanged after decreasing. With the increase of grinding depth, the interaction angle of grinding decreases gradually, and the grinding stability decreases.
