The characteristic of sheet metal process is the few loss of material during process, the short processing time and the excellent price and strength. The sheet metal process with above characteristic is common used in industrial field, but in order to analysis irregular field problems the reliable and economical analysis method is demanded. Finite element method is very effective method to simulate the forming processes with good prediction of the deformation behavior. Among Finite element method. the static-implicit finite element method is applied effectively to analyze real-size auto-body panel stamping processes. which include the forming stage. In this paper, it was focused on the drawing ability factors on auto-body panel stamping by AUTO FORM with using tool planning alloy to reduce law price as well as high precision from Design Optimization of die. According to this study, the results of simulation will give engineers good information to access the Design Optimization of die.

Drawing process at the household goods until industrial site is used in the various filed. This study are drawing process analysis using Auto-Form software which used a Static-implicit time integration method. Analysis simulation result, it was possible to know that choice of a bead and blank size choice can be optimized through a forming analysis. By making apply this to an industrial site the productivity improvement and cost reduction etc. effect able was predicted.

Finite element analysis of sheet metal forming process is generally carried out by the explicit and implicit time integration method. And membrane, shell and continuum element are applied to finite element analysis. Membrane analysis can not provides sufficient information for the process which involve considerable bending effects. Shell element allows the consideration of bending effects, but involves too much computational time. In order to estimate in sheet metal forming processes used Auto-Form software using static-implicit method and shell element. Result, by applying this to an industrial site the productivity improvement and cost reduction etc. effect able was predicted.

The characteristic of sheet metal process is the few loss of material during process, the short processing time and the excellent price and strength. FEA applications with the sheet metal forming process is purpose that increasing due to the potential of time and cost saving. This study are industrial field problem solve using AutoForm which used a Static implicit way. According to this study, the results of simulation will give industrial site good information to access the Design sheet metal forming.
