AutoForm-Sigma is a software product for the sensitivity analysis and optimization of stamping processes. It provides support in tryout, which thereby optimizes tool adjustment and can reduce many correction loops. The effect and sensitivity of design parameters is graphically presented so that the process can be easily followed and development time can be reduced. AutoForm-Sigma is completely integrated in the AutoForm environment. The analysis and description of the results on the part reduces and simplifies time-consuming trials of abstract numbers and diagrams. Expert knowledge is not longer absolutely necessary and can be applied more profitably in other areas of the development process.
