5 Other Industrial Bending Processes 15. Incremental sheet forming ( ISF) process is a flexible manufacturing process to produce complex 3D products at reasonable manufacturing cost. It has been shown that the forming force increases with increasing the vertical pitch tool diameter et al. Hole- flanging is a typical sheet forming process to produce flange features on sheet metal parts. 6 Contour and Hole Flanging. incremental hole flanging) is an interesting processes alternative to the traditional operations with dedicated tools. In the conventional hole- flanging process a sheet metal blank component with a small pre- processes cut hole. Hole flanging by incremental sheet forming processes. Hole- flanging is a conventional forming process in which a sheet blank with a concentric pre- cut hole , the processes outer periphery rigidly fixed by a blank holder, is forced with a punch around a die to produce a smooth cylindrical conical hole- flange. Illustration of an incremental- forming operation. ( a) Flanges incremental on flat sheet. Hole- flanging by incremental sheet forming. Backward Hole- Flanging Technology Using an Incremental Approach % K backward hole- flanging; incremental forming; sheet metal % X The manufacturing of necks on the sheet metal processes parts using conventional hole- flanging process in small series production is sometimes too expensive or even impossible due to the complexity of the product. Hole- flanging by incremental sheet forming However as with all new sheet metal forming processes, there is need for examining its deformation mechanics describing the physics behind the occurrence of failure. the most important challenges in this process. Recent publications proved that hole flanging by incremental sheet forming ( i. Chapter 26 Incremental Sheet Forming.
Hole- flanging by single- point incremental forming ( SPIF) is an emerging sheet forming process with a high potential economic payoff for rapid prototyping and small quantity production. found that hole- flanging hole flanging by. [ 3] investigated the formability processes of hole- flanging by SPIF. Hole- flanging by incremental sheet forming is developing as an innovative metal forming technology for flexible small batch- production of cylindrical or conical flanges in blanks with pre- cut holes. Sheet- Metal Forming Processes and Equipment. Hole- flanging via the ISF process is rapid cost- effective, especially in prototyping low- volume production. SHEET METAL FORMING:. processes 25 Various flanging operations.
The process is seen as an alternative to hole- flanging by conventional press- working due to. Incremental forming of hole- flanges in sheet metal parts is an emerging process with a high potential economic payoff for rapid prototyping and for small quantity production. Incremental sheet forming is a flexible manufacturing process that does not require dedicated dies nor custom tooling. [ 4] compared the relative performance of hole- flanging by incremental sheet forming and conventional press- working. Investigation on a processes new hole- flanging approach by incremental sheet forming through a featured tool Tingting Caoa University of Sheffield, processes Sheffield S1 3JD, processes Shanghai JiaoTong University, 30, China b Department of Mechanical Engineering, Bin Lua, Hengan Ouc, Jun Chena* a Department of processes Plasticity Technology, Shanghai, b, Hui Longb UK.

The results can effectively pre- dict the forming process: when hardening index and orthogonal anisotropy increased, the maximum hole expansion ratio also increased. Huang and Chien [ 9] studied the forming process of the flange hole with. TABLE 1 General Characteristics of Sheet- metal Forming Processes ( in alphabetic order).

In this operation, a hole does not have to be pre- punched. Process Limits of Stretch and Shrink Flanging by Incremental Sheet Metal Forming.
