| Abstract: | According to the structural characteristics and accuracy requirements of typical high-precision holes in aeronautical complex shells, spiral groove inner-cooled step drills and straight edge inner-cooled step reamers were designed. The structure design of special composite forming tools was Improved. The cutting parameters were Optimized. The optimum process parameters for matching special compound forming tools were explored. A process solution for precise machining of high precision holes in complex aeronautical shells has been developed and verified to be feasible. |
