Abstract
This paper presents numerical simulation of blanking process for cold-rolled steel sheet metal. The problem was modeled using axial symmetry in commercial finite element software ADINA. Data obtained by experimental measurement were used to create multi-linear plastic material model for simulation. History of blanking force vs. tool displacement was obtained.
Highlights
Blanking is the most widely used forming operation
These analytical calculations are sufficient for determining basic parameters of blanking process such as maximal blanking force, when problems occur during the manufacturing process the solution is often complicated and can be calculated only by using advanced numerical methods [5]
This paper presents a comparison of blanking process for a steel washer with and without v-ring indenter using finite element method
Summary
Blanking is the most widely used forming operation. It is used both for the preparation of semi-finished products and cutting of metal parts either for final use or as preparation for other technological operations [1, 2]. Simple analytical calculations are usually used during preparation of serial manufacturing [3, 4] These analytical calculations are sufficient for determining basic parameters of blanking process such as maximal blanking force, when problems occur during the manufacturing process the solution is often complicated and can be calculated only by using advanced numerical methods [5]. Use of v-ring indenter improves quality of resulting surface and decreases the necessary blanking force
