How to generate the Tool path in the incremental sheet forming process for Hemisphere using Matlab and Abaqus

Project Overview

In this Abaqus project, you will learn how to generate the tool path for the Incremental Sheet Forming (ISF) process of a hemispherical part using MATLAB and Abaqus.

The main objective of this project is to define the movement of the forming tool using MATLAB and then use the generated tool-path data in Abaqus.

Incremental sheet forming model for the hemisphere.

Incremental Sheet Forming of a Hemisphere

In this example, the incremental sheet forming process is performed to produce a hemispherical shape. The forming tool moves progressively over the sheet and gradually creates the desired geometry.

The tool follows a spiral path during the forming process. This continuous movement allows the sheet to be formed gradually.

Spiral Tool Path

The tool moves along a spiral trajectory during the incremental forming process. The spiral path is generated using MATLAB and is then used to define the tool movement in Abaqus.

The generated path contains the coordinates required to control the position of the forming tool during the simulation.

Hemisphere Geometry

The geometry considered in this project is a hemisphere. The diameter of the hemisphere is 100 mm.

Generating the Tool Path Using MATLAB

MATLAB is used to generate the movement of the forming tool along the spiral path. The procedure consists of several steps that are explained in the tutorial.

Step 1 – Define the Time Period

In the first step, the time period of the tool movement is defined using MATLAB. In this example, the total time period is 800 seconds.

Step 2 – Export MATLAB Data to Excel

After generating the required tool-path data in MATLAB, the data is exported to Excel. The Excel data is then used to define the tool movement in Abaqus.

Step 3 – Define the Tool Movement

The generated coordinates are used to define the movement of the forming tool. The tool follows the generated spiral path during the Abaqus simulation.

The remaining steps required to generate and implement the complete tool path are explained in the full step-by-step training video.

Tool Path Data

The tool-path coordinates are provided in Excel files and include the X, Y, and Z amplitude data required for defining the tool movement in Abaqus.
