Nagforge is a knowledge based software program for automatic and manual design of forging sequence for hot and warm forged parts. It allows the User to capture manufacturing knowledge and use it to design progressions for similar parts.

NagForge utilizes a combination of design logic, knowledge-based rules and simple analyses to determine a forging progression automatically in minutes.The sequence designs created in NagForge can be tested effortlessly in NAGSIM_Gen.2D FEA simulation software.

In addition to sequence design, NagForge has a 'Smart' database and analysis module to store 'Knowledge' and use it to improve the design and manufacturing processes.


  • Search its 'Smart' database to find similar parts and the knowledge available including sequence designs, lessons learnt, tool life etc. Prevent reinventing sequence design or spending hours to design a wrong forging sequence.
  • Create hot forging part profile from machined part profile.
  • Obtain alternative sequence designs for forging a part in a few minutes.
  • Calculate flash dimensions for closed die forgings.
  • Calculate die angle for Chevron free extrusion.
  • Create reusable sequence-design templates of your own designs or designs from NagForge. Use these templates to 'Zip through' progression design for similar 'Family of Parts'.
  • Automate and standardize sequence design of similar parts.
  • Create DXF output of sequence designs in a few minutes
  • Select optimal blank diameter
  • Reduce number of forming operations
  • Obtain estimated loads, pressures and deformation
  • Estimate load distribution on a multi-station machine
  • Prevent designs that overload the tooling or overstrain the part
  • Teach forming design to new personnel


  • NagForge is not a FEA simulation program. It can not predict metal-flow defects and stress distribution in tools.
  • Nagforge can be used only for parts with some symmetry such as parts made on upsetters, closed die forgings with and without flash, ring rolling and open die forging of symmetrical and long parts. Parts can have features such as polygons, flats and splines.

Alternative Forming Progressions in Minutes
In general, there is more than one forming sequence by which a part can be formed. The number of designs depends upon the constraints such as part geometry, material being forged, allowed number of operations, wire / rod size etc. NagForge has its own design logic to determine various possible ways a part can be formed. Because the program looks for all possible designs and applies its logic without fail, NagForge can come up with design concepts that even experienced designers may overlook.

Design by Command
'Design by Command' feature allows the user to create his/her own design interactively in a few minutes. The interactive session, consisting of questions by the program to determine design intent and the responses of the user, is saved in a session file. This session file can be used as a template to create progression design for similar 'Family of Parts' in minutes.

Objectives of NagForge 'Smart' Database and Analysis Module

  • Create and maintain a historic database of parts designed, quoted and manufactured.
  • Capture and retain the knowledge gained from experience.
  • Improve sequence design, quoting and manufacturing processes.
  • Eliminate duplication of effort.
  • Reduce print-to-part time.

Search and Analysis Capabilities - 'Smart' Database Module

  • Part: Search for similar parts, parts with certain features such as hex, lobe etc, parts within specified length, diameter and volume.
  • Design : Existing Auto or Manual designs for current or similar parts.
  • Material - usage.
  • Wire /Rod size - usage.
  • Forming Machine - usage
  • Tool Life - for similar parts
  • Cost - quoted and manufacturing.
  • Lessons learnt on similar parts.

Template' Designs for 'Similar Parts' or 'Family of Parts'
For any part that is similar to a template in the database, NagForge can follow the template design / session file to create forming progression in minutes.

Manual Design
In addition to automatic design, NagForge has a separate module for creating a forming progression manually. Using computer aided techniques, the user can quickly construct a forming sequence according to his/her own concept. The designer can also start from a computer-generated design and modify it.

DXF Input and Output
In NagForge, a part is constructed using simple shapes called primitives. The geometry of parts can also be imported from CAD systems such as AutoCad, SolidEdge etc. The NagForge output including sequence designs can be saved in DXF format for input to other CAD systems.

Forging Profile from Machined Part Drawing
Nagforge has a separate module for creating Forging Profile from machined part drawing. User can specify machining allowance on outside profile as well as bore. Fillet and corner radii as well as forging draft angles can be specified.

Automatic Creation of Analysis File for NAGSIM.2D
For some of the sequence designs, NagForge can create the analysis file for simulation of the sequence designs in NAGSIM.2D. For new parts, for which tooling designs are not available, this saves considerable effort required to create process drawings for FEA simulation.
