摘要：

Incremental Sheet Forming (ISF) is a forming process widely used to obtain small batches or prototypes. By improving forming strategies, the process can be used in a wide range of applications. However, this technology still presents some drawbacks. The dimensional accuracy between the 3D CAD model and the final product is one of the key challenges for this technique. The springback phenomenon during the incremental forming process is an important reason for the lack of accuracy. In order to study the mechanism of this phenomenon, the geometry of the sheet metal was measured in two different stages of the conventional production chain. First, the geometry of the sheet metal part was acquired after the forming stage, without be released from the blank holder. Then, the final geometry was achieved after the cutting process from the original sheet. A 3D scanning system was used to measure and inspect the springback phenomenon of each step. A reverse method is proposed to design the new tool path for compensation of the springback.
