Project Overview
In this Abaqus project, the Single Point Incremental Forming (SPIF) process is simulated to form a truncated pyramid. The simulation is performed using Abaqus to demonstrate how a moving forming tool can progressively deform an aluminum sheet into the desired geometry.
In the SPIF process, a hemispherical forming tool moves along a predefined trajectory on the sheet. The tool gradually deforms the sheet until the final shape is obtained.

Truncated Pyramid Forming
The final geometry produced in this simulation is a truncated pyramid. The forming tool progressively moves over the sheet and causes the aluminum plate to deform into the desired shape.
Unlike conventional forming methods that require a dedicated forming die, incremental sheet forming produces the desired geometry through the controlled movement of the forming tool.

Tool Movement
During the simulation, the forming tool follows a rectangular path in the X-Y plane. This controlled movement progressively deforms the sheet and produces the truncated pyramid geometry.
The tool also rotates about the Z-axis with a constant angular velocity during the forming process.

Forming Tool
The forming tool is modeled as a three-dimensional discrete rigid surface. The hemispherical end of the tool comes into contact with the aluminum sheet and gradually forms the desired geometry.

Aluminum Sheet
The sheet used in this simulation is made of aluminum. The sheet has a length of 400 mm, a width of 200 mm, and a thickness of 1.5 mm.
Contact and Friction
Contact is defined between the forming tool and the aluminum sheet. The coefficient of friction between the tool and the sheet is taken as 0.1.
The contact interaction allows the forming tool to transfer forces to the sheet while moving along its predefined path.
