Single point incremental forming (SPIF) process is the latest sheet metal forming technique, which developed in the around 1990, this process could generates a local strain on a sheet metal by mean of small rotation forming tool travel follow CNC toolpath on sheet metal blank to form a shell part. The incredible elongating without failure occurs is the main advantage of this process. This paper attempt to explain the deformation mechanism of steel sheet that formed by SPIF in the metallurgical views. The different degree of deformation were investigated by optical microscope, the grain size deformation was used as a data for math modeling of the deformation mechanism.

Abrasive Finishing

In this paper the Magnetic Abrasive Finishing (MAF) was utilized after Single Point Incremental Forming (SPIF) process as a combined finishing process. Firstly, the Single Point Incremental forming was form the truncated cone made from low carbon steel (1008-AISI) based on Z-level tool path then the magnetic abrasive finishing process was applied on the surface of the formed product. Box-Behnken design of experiment in Minitab 17 software was used in this study. The influences of different parameters (feed rate, machining step size, coil current and spindle speed) on change in Micro-Vickers hardness were studied. The maximum and minimum change in Micro-Vickers hardness that achieved from all the experiments were (40.4 and 1.1) respectively. The contribution percent of (feed rate, machining step size, coil current and spindle speed) were (7.1, 18.068, 17.376 and 37.894) % respectively. After MAF process all the micro surface cracks that generated on the workpiece surface was completely removed from the surface.
