Simulative Tests for Sheet Metal Forming
Strip-Reduction Test (SRT) and Strip-Bending Test (SBT)
Simulative tests are important in modern metal forming. The tests provides the theoretical and experimental background to the utilization of scientific analysis in conjunction with formability, tribology and process laboratory tests. This covers machine-tools, tool systems and practical problems that are commonly found in daily production of metal components. Here, we show some examples within our laboratory practices – strip-reduction test and strip-bending test. The strip-reduction test replicating an ironing process and the strip-bending test emulating a deep-drawing test. Both simulative tests are performed to identify the most promising tribological system for evaluating friction and wear in sheet-metal forming under dry and oil-lubricated conditions. Both of the experimental set-ups as shown in the figure below offered multiple runs of forming processes from a coil to simulate accurately the industrial sheet-metal forming conditions.
