2 Global competition, smart R&D investments to create innovative products with the best possible quality at competitive prices, these are the challenges today s forming industry is facing. It is helpful to get a detailed insight into development and manufacturing processes, to assure that innovative ideas will find their way into production - without the risk of failure within the development process. Today, companies in the forming industry worldwide rely on process simulation, which frontloads the manufacturing process into the virtual world even before production has started. This approach gives companies control over manufacturing processes as well as over costs related to process layout and production and the possibility to react flexible to special requirements. The product and service offerings of Simufact have been developed to meet the requests of the forming industry and provide a solution. Simufact supports its customers globally by being a solution provider of production technology and process simulation for the optimization and design of production process. Simufact develops and distributes Simufact. forming, an industry sector solution, easy to implement, user friendly, and based on leading standard technologies. Essentially we have been able to improve our overall process regarding process stability with simulation. It helped us to improve quality, productivity, and to save material. To us, forming simulation means progress, innovation, and cost savings. Gerald Oppelt, Manager Production Technology, Uponor The cooperation with our technology partner Simufact has evolved over many years, especially in the area of ring rolling. Today, by combining the experience of our engineers with simulation technology, we are in the position to receive process simulation results that are between 90 and 98 percent close to reality. Jürgen Schüler, Leader Technical Planning, Neumayer Tekfor The importance of simulation within the forming industry is constantly increasing and helps to be one step ahead of your competition, because companies within our industry, that use simulation, can save energy and material, and are able to produce lighter components. Dr. Theodor L. Tutmann, Managing Director, German Forging Association (IMU) By using simulation software, my abilties as a forging die designer have enhanced with many folds. It helps me to visualize the concept of the physics of metal flow in the cavities of different stages of impressions. This is a very powerful and recommended tool for a designer. And in the end it saves company money. Senior Manufacturing Engineer Cornell Forge Co, Chicago U.S.A

Development errors have to be avoided and processes have to be optimized as early as possible within the development phases.

3 Challenges in Forming Technology The global competitive pressure companies in the forming industry are facing is immense. Customers requirements are increasing constantly and the cost pressure force companies to change and optimize their design and manufacturing processes. Development errors have to be avoided and processes have to be optimized as early as possible within the development phases. The goal of an optimized development process should be that a tool or part is only physically tested to validate the data coming from simulation. What if the first physical test could already provide the approval for production? How can you assure, that production uses the most cost-efficient process? How can you guarantee, that the know-how of forming processes gathered by your experienced employees stays within your organization if someone leaves? How do you reduce cycle times for new part development from several to one week? These are some of the questions companies in the forming industry are confronting in their daily work. To sustain in this market successfully, it is unavoidable to use suitable instruments, which help companies to reduce manufacturing risks, leave freedom for new and innovative ideas, and give detailed insights into manufacturing processes. It is crucial to define the best possible manufacturing process without repetitive physical tests. This is where the product and service offerings of Simufact are fitting in. Frontloading of Physical Testing into the Computer: process reliability - method optimization - cost reduction Companies in the bulk metal forming industry, which use process simulation, confirm that they could reduce physical testing by 50%, immediately after the implementation of the new methods. They also confirm that cycle times for new part developments can be reduced from 3 weeks to 1 week a huge cost saving potential. With the growing experience of the users, these numbers can be improved even further. Traditionally companies could answer questions about forming faults, tool forces or the related tool life quantity only after the first (second or third ) physical test. Today, thanks to virtual testing, mistakes can be found earlier, avoided and therefore costs can be saved. Benefits provided by process simulations: Process stability through: better knowledge about details of the forming process less faults in forming evaluation of more variants and risk free testing of new ideas Method optimization through: reduction of forming operations less machining optimized material usage Reduced costs in tool and process development through: fewer testing of tools less production downtimes for trial runs shorter development times Cost reduction in serial production through: increased tool life optimized utilization of machine capacity increased production line availability less material waste

4 Simulation Technology for Practical Use Simufact.forming is a tool for practical use in forming technology. Other simulation environments often require expert computer science knowledge to program complex models. With Simufact.forming this is not the case. The user does not need to deal with the mathematical forming theory nor does he have to handle simulation specific details. Simufact.forming is practical and easy to learn. The user can focus on the details of the forming process instead of on the software. Simufact.forming s user interface allows an easy operation of the software. Simufact. forming is the layout software of choice for tool and process developers, supporting them in and simplifying their daily work. With only a few mouse clicks, all standard forming processes can be built and evaluated. But Simufact.forming offers even more. Many additional functions are available to enable the experienced user to model every complex process imaginable. Flow lines can be defined easily. Shear trap or middle line tracing as well as fibre flow visualisation deliver essential information for the evaluation of the forming process. The calculation of tool forces and stresses helps to define the best possible tool layout, and to avoid premature tool failure. CAD data can automatically be imported via direct interfaces. Simufact.forming deals with all areas of forming technology and guarantees a realistic representation of the processes. It includes, among others: full 3D functionality and 3D representation of all tools & parts the actual kinematics of a machine, no matter what type or how complex it might be material behavior - elasticity, plasticity, increase and decrease of strain hardening as well as temperature and velocity related effects friction and contact between tools and forming parts self contact of forming parts to predict folds thermodynamics of the process: initial heating conditions, heat transfer into tools and environment, temperature increase due to forming energy and friction, etc. The quality of the results is guaranteed since Simufact.forming is based on MSC.Software s powerful standard solvers MSC.Marc - the finite element solver for nonlinear applications - and MSC.Dytran - the finite volume solver. Both products are continuously developed further and enable the representation of complex nonlinear physics of the forming process with high precision. Simufact.forming stands out by its easeof-use and short learning phase. The main characteristics of the practice oriented user interface are: easy and intuitive windows-like user operations (drag & drop) all capabilities available in one single environment (2D, 3D, Pre-, Run, Post-) quick and easy to learn terminology of forming industry clear separation into object area (tools, machines, material, etc), process area (forming operations) and graphical model/ results area all objects can be made available in the database template-technology Fully automated remeshing capability for hexahedral and tetrahedral meshing technology All types of low-alloyed and stainless steel, copper alloy, brass, aluminum alloy, and inconel are available within the material database.

Simufact.forming die analysis - tool life evaluation & optimization For a detailed insight into the tools, the supplementary module Simufact.forming die analysis is the module of choice. Tool preloads can be simulated under realistic internal pressure, the tool behavior can be investigated under realistic manufacturing constraints in coupled or uncoupled analysis. Therefore it is possible to analyze tool failure and to evaluate different tool concepts. Simufact.forming kinematics - representation of arbitrary machine motion sequences The supplementary module Simufact.forming kinematics allows the automated modeling of complex machine motion sequences such as the complete reduction plan with several re-heating steps, as typical in open die forging. This module is usually customized to the customer s needs. If needed, machine controller data can be directly fed in as a simulation parameter. Simufact.material - insights into material structure Simufact.material is a modular tool in itself and consists of: Basic, Microstructure, and Transformation. The basic version of the tool includes a broad range of material data with a wide spectrum of grades. The modules microstructure and transformation allow the calculation of phase transformation and fraction in thermomechanical processes as well as the investigation of recrystallization processes (dynamic and static) and grain growth. The Simufact product line covers all major areas of a simulation environment for bulk metal forming process simulation. Thanks to its comprehensive and well tested CAD/CAE connection - all standard CAE and many direct CAD interfaces are available it is possible to embed the software environment into any existing CAD/CAE landscape.
