“…They divided the deformation zone into three distinct regions: (a) the sinking, (b) the forging, and (c) the sizing zones. Domblesky et al investigated the radial forging of large diameter tubes and multiple pass radial forging by using the finite element method [11,12]. They obtained the distribution of temperature, strain rate and strain in the deformation zone by this technique.…”

“…Using slab method analysis, Lahoti and Altan [2] analyzed the mechanics of radial forging process. Domblesky et al [4] presented a finite element model and obtained strain, strain rate and temperature distribution in radial forging. Jang and Liou [5] also modeled radial forging by finite element method to obtain residual stresses.…”

“…They implemented a slab method of analysis to develop a general model of the hot and cold radial forging of rods and tubes. Domblesky et al (1995) used finite element based analysis to optimize the radial forging operation. Liou and Jang (1997) advocate a robust design methodology to optimize forging process parameters to give optimum stress distributions in products through FEM analysis.…”

Response surface methodology Radial forging Design of experiment (DOE) S/N ratio Analysis of variance (ANOVA) a b s t r a c tThe present competitive market is focusing industrial efforts on producing high-quality products with the lowest possible cost. To help accomplish this objective, various quality improvement philosophies have been put forward in recent years and of these Six Sigma has emerged as perhaps the most viable and efficient technique for process quality improvement. The work in this paper focuses on implementing the DMAIC (Define, Measurement, Analyze, Improve, and Control) based Six Sigma approach in order to optimize the radial forging operation variables. In this research, the authors have kept their prime focus on minimizing the residual stress developed in components manufactured by the radial forging process. Analysis of various critical process parameters and the interaction among them was carried out with the help of Taguchi's method of experimental design. To optimize the results obtained and to make the analysis more precise and cost effective, response surface methodology (RSM) was also incorporated. The optimized parameters obtained using Taguchi method and RSM were then tested in an industrial case study and a trade-off made to finalize the recommended process parameters used in manufacture.
