摘要：
To research the surface quality of double-stage incremental forming, response surface method was adopted to model and optimize the overall surface roughness in double-stage incremental sheet forming (DS-ISF). First, the Box-Behnken design approach was used to develop the experimental plan where four main process parameters (wall angel α, angle interval Δα, step size Δz and feed rate V) were considered. Second, a mathematical model between process parameters and roughness was established and verified by experiments and analysis of variance (ANOVA). Then, the effect of these parameters and their interactions on surface roughness were investigated by adopting ANOVA technique. It is found that step size has the maximum influence on the roughness, followed by angle interval, wall angel and feed rate. Roughness value first decreases and then increases with the increase of V, and increases with the increase of Δz, Δα and α. In addition, a optimal set of parameters was provided after verified. © 2017, Editorial Board of Journal of Huazhong University of Science and Technology. All right reserved.
