- Abstract:
- Since the complicated helical groove on the combustor inner wall of rocket engine decreases the machining efficiency greatly, the modeling of integral assembly in the machining center and the whole simulation for the digitization machining process were conducted by using digital simulation technology. A high-efficiency machining technical proposal for machining the helical grooves on the combustor inner wall is proposed. The five-axis stick milling cutter machining technology was adopted instead of the former helical groove milling cutter machining approach. Therefore, the machining quality was improved obviously and the machining efficiency was increased by nearly three times.
