...De Waele Wim; Faes Koen; Van Haver Wim Electromagnetic punching of tubular products is considered to be a promising innovative perforating process. The required punching energy decreases when using high velocities. Also, less tools are required when compared to conventional mechanical punching...

... obtained with optimal shearing conditions. 30 03 2011 17 11 2011 15 12 2011 15 12 2011 fracture metal stamping metalworking punching shearing steel Edge fracture is one of the major issues for stamping advanced high strength steel (AHSS). In addition to the material...

.... The output parameter of the ANFIS model is spring-back and the input parameters are sheet thickness, sheet orientation, and punch tip radius. The performance of the ANFIS model in training and testing sets is compared with those observations. The results indicated that the ANFIS model can be applied...

... including sheet thickness, punch speed, interface friction at the punch surface, and interface friction at the die surface. The results show that probabilistic design improves the yield (probability of good parts) to 99.98% as compared to the 48.04% yield realized by the traditional deterministic design...

...Isamu Aoki; Masahiro Sasada Burr-free blanking requirements are strong; however, the thinner the product, the more difficult the burr-free blanking will be, due mainly to the control of the punch penetration depth. In this study, the principle of accompanying burr-free blanking problems...

...Toshihiko Mori An integrated micropress was developed for ultrafine piercing of metallic foils by a SiC fiber punch. The fiber punch was produced by a series of processes that use buffing and electrolysis operations. The technology incorporates unique tooling and fixturing techniques to handle...
