Testing of formed joints on a designed prototype station

In presented paper perform prototype machine which consist of two independent motion axis equipped with force sensors. Used force sensors provide control of forming connection. Special design of the machine provide to make tensile strength test on it. Prepared nine samples to carried out tests, which revealed the influence between change of jaws displacement during plastic deformation and strength of that joint. Created prototype stand base on two independent drive units allow to make that connection possible. Choosing right parameters leads to generate joints which are more than twice stronger than basic sample reaching more than 920N.
