“…Therefore, the deformation energy model is obtained from the use of coded parameter values and the elimination of insignificant factors, as presented in equation (6). From the P value in Table 5 and the coefficient in equation (6), all four factors have remarkable linear effects, especially the thickness (C).…”

“…4,5 In recent years, environment and sustainable problems for plastic process have considerable attention, as have SPIF processes. 6,7 Duflou et al 8 proposed that it can decrease energy use and enhance resource utilization in incremental forming processes by optimizing processing parameters. Branker et al 9,10 analyzed the cost, energy, and carbon dioxide emission in SPIF and found that the cost and energy usage reduce from US$4.48 and 4580 kJ to US$4.10 and 1420 kJ, respectively, by increasing the step down and feed rate.…”

The deformation energy in single point incremental forming has an immediate impact on the processing cost, the heat and the wear effects between the tool and the formed material. Meanwhile, poor forming quality is still one of the largest challenges for the development and commercialization of this method. Therefore, the goal of this study is to search for the optimal working condition for lower energy consumption with better forming quality during the forming process. A Box-Behnken design for a cone parts forming process has been performed. The effects of four input parameters (step down, tool diameter, wall angle, and initial sheet thickness) on three outputs-deformation energy, surface roughness, and geometric error-have been investigated. With the target of minimal synchronization of deformation energy consumption, surface roughness, and geometric error, which are 1522.4 J, 0.97 mm, and 1.939 mm, respectively, in this case, four processing parameters were optimized with tool diameters as 16 mm, step down as 0.5 mm, sheet thickness as 0.57 mm, and wall angle as 65°. With optimization of deformation energy and surface roughness, in conjunction with geometric error compensation, an increased accuracy of the resulting parts can be obtained with minimum deformation energy and surface roughness.

“…SPIF process would be useful for prototyping and small-batches production for automobile, biomedical and aerospace industries [5]. Disadvantages of SPIF process: long forming time when compared to deep drawing process, small-lot production, low accuracy of the geometry, high springback, in bending edges and convex radius areas [6].…”

Single Point Incremental Forming process (SPIF) is a modern forming technique of sheet material. Principles of the process are based on manufacturing by layers-two dimensions layers with step size depth of the tool path. The movement of a hemispherical forming tool is using Computer Numerical Control (CNC) machine to produce the profile of the final product. The description of the process is more complicated by highly nonlinear boundary conditions. The paper presents a study of the effect of the flat forming tool profile through FEA on SPIF that permits the modelling of complex product geometries, material behaviour and boundary conditions. The results showed that the model of simulation can predict the behaviour of contact tool-blank, and the accuracy of product.

Abstract. Single Point Incremental Forming, SPIF and Two PointIncremental Forming, TPIF are two types of Incremental Sheet Forming ISF processes with high economic potential payoff for rapid prototyping applications. The process requires a CNC machining centre, a spherical tip tool and a simple support to fix the workpiece. The process is more complicated by highly nonlinear boundary conditions, namely contact and frictional effects. However, this process, numerical approach, dominated by the Finite Element Method, FEM is being used. The paper presents the data and main results of a study on the effect of using two forming tool movements through FE analysis. The certain process conditions referring to the test blank, tool, etc., applying ANSYS application program. The results show that the upper TPIF process is more stable during the deformation process steps by chattering statuses evaluation and improve the strain distributions of the deformed blank.
