Geometry of the Tube

Defining the tube product:

•  The tube should be meshed with shell elements;

•  Select the proper tube face type

Outer

Inner Middle

Note:

The Geometry page is not compulsory The user can also set the bending

process from the Bending page directly

Geometry of the Tube

Calculate - Calculate the center line,

perimeter, diameter and the process info;

Edit - Edit the center line;

Swap - Adjust the starting point of bending;

Simplify - Convert the center line from

discrete point to arc and line

The illustration shows the current section

of the tube and the perimeter of the tube

Min Perimeter - The minimum perimeter

of the tube section;

Max Perimeter - The maximum perimeter

of the tube section;

Length - The total length of the tube

center line;

Diameter - The tube blank diameter

Tube Blank Generation

•  Outer diameter and Full length are generated automatically;

•  The user can set the Element size of the tube blank based on the tube diameter;

•  Click Create to generate the tube blank

Note:

Before calculating the tube center line, the user must first define the tube thickness

Tools Generation

•  After generating the process, the tool

parameters are calculated automatically;

•  Click Create to generate the tools;

•  Click OK to enter the setup GUI

Setup Definition

•  The tube blank, tools and process are generated automatically;

•  The user can change the tube blank material, tool process control and other

parameters
