Abstract: For a magazine part with a deep runner, complex surface and prone to chatter and interference during machining. In order to improve the efficiency and quality of the milling process, a five-axis machining process and special tools were designed according to the structural characteristics of the magazine part. CNC path planning was completed using the 5-axis impeller part CNC machining software MAX-PAC, and was verified using Vericut. The test machining was completed on the machine and the results showed that the complex surfaces in the magazine were of good quality.
