Incremental sheet metal forming (ISMF) is a highly flexible and versatile process to produce complex sheet
metal parts and rapid prototypes. Its adaptability to (CNC) systems is excellent through direct control of CAD data,
minimizing the use of heavy machines, high cost tooling and pressing equipment. A sheet of metal is formed by using a
simple forming tool driven by a CNC milling machine localizing pressing force to plastically deform the part during
progression. In this work, like pyramid shape manufactured by(SPIF) process without using any dedicated dies. The aim
is to measure the influence of forming the angle on the dimensional accuracy (depth error) of the formed part. Different
angles (30°, 45°, and 60°) used to create pyramid shape and all the experiments carried out on an aluminum alloy sheet
with0.5 mm thickness by using a three-axis conventional milling machine, this machine also used to measure dimensions
accuracy of the part. Results show that the forming angle (30°) is gives the higher geometrical accuracy when forming
the pyramid shape.
