| Abstract Scope |
The two principal process steps of Radial Rotation Profile-Forming are the production of the preform and the subsequent radial profile forming of the hollow part. During the preform production wrinkles occur and these wrinkles can be formed directly in the indentation of the mandrel. In the second process step, the wrinkles are used to form the finish profile of the component. However, there is no wrinkle formed in every indentation. In this case, high sheet thinning and inhomogeneous properties occurs due to forming of the final profile. To avoid this disadvantage, a local laser heat treatment is carried out to control the wrinkling for the first time. The laser treatment leads to local hardening areas and wrinkling occurs in the area with the lower strength basic material in every indentation. The experimental and numerical investigation of the laser heat treatment and the influence on the two forming steps are shown. |
