喷丸成形工艺已广泛用于制造单、双曲率的机翼蒙皮零件。实践证明,这种方法不但设备简单,成本低,具有足够的精度,并且能提高机翼的抗疲劳强度以及抗应力腐蚀的能力。然而,传统的喷丸成形工艺带有手艺的特点,成形零件的再现性主要取决于操作者的技术水平。喷丸成形机床历来也都是人工操纵的。近期,波音公司在Wheelabrator-Frye公司和Alien-Bradley公司的协助下,发展了一种以实验数据为基础的CNC喷丸成形系统,采用叶轮式喷丸机,应用计算机数字控制系统、比以前喷丸成形中用样板检验,以及送进速度,弹流速度和弹流量等均由人工调节具有明显的优越性。与蠕变成形相比,新型的CNC喷丸 Shot peening processes have been widely used to make single and double curvature wing skin parts. Practice has proved that this method is not only simple equipment, low cost, with sufficient accuracy, and can improve the anti-fatigue strength of the wing and resistance to stress corrosion. However, the traditional shot peening process has the characteristics of craftsmanship. The reproducibility of the formed parts mainly depends on the technical level of the operator. Shot peening machines have always been artificially manipulated. Recently, Boeing, with the help of Wheelabrator-Frye and Alien-Bradley, developed a CNC-based shot peening system based on experimental data using an impeller-type shot blasting machine using a computerized numerical control system, Pill forming test with a model, and the feed rate, the elastic velocity and elastic flow by manual adjustment has obvious advantages. Compared with creep forming, the new CNC shot peening
