Integration of Master Cam and Ls -Dyna for the Single Point Incremental Process

摘要

Single point incremental forming (SPIF) is a sheet metal forming process that the planning of precise tool path is a very important procedure. It is known that the tool path generated by Master Cam is suitable for axisymmetric and non-axisymmetric shape samples. However, G code directly generated by the Master Cam cannot be exported to numerical simulation software such as Ls-Dyna. Therefore, we propose a method to integrate the Master Cam and Ls-Dyna to realize SPIF. A cold-rolled steel sheet was formed in a numerically controlled milling machine to test formability and surface roughness for verification of the numerical simulations conducted on Ls-Dyna.
