Investigation of the Axial Forming Force during Low Frequency Vibration Assisted SPIF

Applied low frequency vibration in a single point incremental forming technique has recently been used. Through process of the Single-Point Incremental Forming (SPIF), the precision was affected by forming force and can cause sheet metal fracture. The magnitude of the forming forces is necessary for designing suitable models for the metal forming of the Incremental Layer. Using vibration with various values of frequency (20, 40, 60, 80, 100) Hz with amplitude (0.1mm) can decrease the forming force. It is established that the reduction rate in axial force is about (11.63%) at the frequency of (100 Hz), it is the lowest for the selection of frequencies introduced. The experimental force result has been compared with analytical solution
