| Abstract: |
| This paper focuses on the CNC machining process of a product with complex shape and structure and 34 M36×3-6H threads. Research processes were carried out and whirlwind milling method was used. CNC machining programs were also prepared. All these give an effective solution to solve the problems of large diameter threads machining. Based on this, the CNC machining program was parameterized, so any diameter thread with any pitch and any depth can be achieved theoretically. This method was also used in other type products. |
