• Available in Database Form
• Select Material by “mouse-click”
• User-extendable Database
Comprehensive Material Data
• Material Data depends on
– work hardening
• temperature
– strain rate

Realistic Press Characteristics
• Most Press Types Available
• User-extendable Database
• Most Press Types Available

Friction
• Friction Influences:– load and energy requirements– metal flow– pressure distribution– die wear
• Friction Models– Coulomb friction– plastic shear friction– combination
• User-extendable Database
![Page 6: Full Representation of Shop Floor Forging Practice Advantage by Increased Insight The Virtual Forging Shop MSC.SuperForge](https://reader036.vdocuments.mx/reader036/viewer/2022070409/56649e905503460f94b94ebb/html5/thumbnails/6.jpg)
Temperature Effects• Needed to account for:
– proper metal flow – die chilling during forming– thermal stresses during cooling
• Heat Transfer between Work Piece and Dies
• Heat Transfer to Ambient
• Heat Conduction within both Work Piece and Dies
• Heat Generation due to Plastic Deformation

Elasticity Effects
• Needed to account for:– deviation from desired shape (tolerances)– thermal stresses– proper die loads (die overclosure)
• Elastic-plastic material model

Positioning of Work Piece
• Influences Metal Flow
• Automatic or Manual Positioning– sliding is accounted for !!

Accurate Workpiece Positioning
![Page 10: Full Representation of Shop Floor Forging Practice Advantage by Increased Insight The Virtual Forging Shop MSC.SuperForge](https://reader036.vdocuments.mx/reader036/viewer/2022070409/56649e905503460f94b94ebb/html5/thumbnails/10.jpg)
Multi-Stage Process Modeling
• Automatic Transfer of Material Properties between Stages– stress, strain, temperature
• Transport of Work Piece between:– furnace and dies– different dies
• Intermediate Heat Treatment• Handling by “mouse-click”
![Page 11: Full Representation of Shop Floor Forging Practice Advantage by Increased Insight The Virtual Forging Shop MSC.SuperForge](https://reader036.vdocuments.mx/reader036/viewer/2022070409/56649e905503460f94b94ebb/html5/thumbnails/11.jpg)
Powerful CAD Interface• CAD Transfer via STL (Standard Triangulation Language)
– standard format used in rapid prototyping techniques– commonly available in all CAD packages
• No ‘Finite Element’ Experience Required
• No Meshing
STL

• Why ? – enables precise filling of intricate die regions if metal
flows into such regions– no user intervention required
• Able to capture small intricate die details by using:
