Acronym: UltraCaulk

Objective of the research project "UltraCaulk" was the development of a hybrid manufacturing process for the ultrasonic-assisted forming of difficult-to-deform materials, such as high strength steel. The superimposed oscillation enables a considerable reduction of the required forces and therefore the workpiece loading. The sub-project "development of the fundamentals and the simulation model" was mainly concerned with the identification of relevant process parameters and potential causes for the force reduction occurring during ultrasonic-assisted compression testing with different metallic materials. For stainless steel X17CrNi16-2 an amplitude dependent force reduction of up to 43 % is generated, which could be traced back to thermal and microstructural influences
