4 Bending Process Process Details 3 Work Piece Material Properties Yield-, ultimate Strength Ductility Young s Modulus Geometric Properties Tolerance in thickness High Quality Precision Material Machine Deformation Tools Bending Sequence +/- 0.3 Bending Angle +/- 20 µm relative Tool Position Bending Angle

5 Current Situation Mechatronic System TruBend Cell Tests during Product Development dynamic analysis static FEM analysis real world testing...

6 Current Situation Current Situation standardized processes of the product development 5

7 Current Situation Current Situation standardized processes of the product development documented requirements for products and components 5

8 Current Situation Current Situation standardized processes of the product development documented requirements for products and components sophisticated documentation of solutions - e.g. mechanical domain: 3D CAD, 2D drawings,... 5

9 Current Situation Current Situation standardized processes of the product development documented requirements for products and components sophisticated documentation of solutions 5 coverage of test cases checked manually responsible person for test case transfer of data done partially manual consistency of data, checked by test engineer

10 Challenge Potential of Improvement Testing during Product Development - coverage of all relevant components - coverage of all requirements - relevant test cases are up to date at a certain gate - test cases, comprehensible by none-specialist 6 Data Transfer - automated data transfer - consistent data at test execution - automated update of test cases
