CAD import

VeraCAD imports the 3D geometry of a forging part via standard interface (IGES, VDAFS or STL) from any CAD system.

Derive mass distribution

First a spine line is digitized (yellow line). Along this line VeraCAD calculates a mass distribution diagramm. The final roller part based on the mass distribution is created automatically (blue line).

Create calibration plan

Depending on total reduction the calibration plan has 2 passes. VeraCAD makes proposal of cross-section shape and reduction rates. More technology parameters can be supplied in the property grid window.

3D geometry of tool segments

After any parameter change, roller products and tool segments are updated immediately. These are suitable both for CNC-milling as well as for a FEM simulation. The CAD export is done via a standard interface.

2D technical drawing

A fully dimensioned technical drawing exists for each roller pass, tool segment and for the calibration plan.
