download PDFAbstract. Due to the use of high-strength steels to achieve lightweight construction goals, conventional shear cutting processes are reaching their limits. Therefore, so-called high-speed impact cutting (HSIC) is used to achieve the required cut surface qualities. A new machine concept consisting of linear motors and an impact mass is presented to investigate HSIC. It allows all relevant parameters to be flexibly adjusted and measured. The design and construction of the test bench are described. The validation was performed with HSIC of a mild deep-drawing steel sheet. The velocities as well as the cut surface were analysed.
