QForm — is a computer-aided engineering software package for development, analysis and optimization of metal forming technologies developed by QuantorForm Ltd. = Description = QForm operates on Windows OS and is available in local, client-server and cloud versions. The software suite contains 4 main programs: QForm V8, QForm RingRolling, QForm-Extrusion and QForm Extrusion Die Designer. The software is used in aerospace, automotive, mining, energy, metal forming and other industries. The main purpose of QForm software is to lower the costs of manufacturing by optimization of technology, decreasing raw material used as well as the number of trial forging operations and/or tool corrections. = Products = QForm V8 — finite element method (FEM) program for 2D and 3D metal forming processes simulation based on the Lagrange approach. The simulation results are shown in parallel to the simulation progress so the user can monitor the technology and correct it without waiting for the simulation to finish. QForm V8 allows creating chains of processes of different types, combining 2D and 3D, and then simulating the entire chain of processes automatically. Standard fields available in the workpiece include; temperature, mean stress, effective stress, plastic strain, strain rate, velocity in any vector, distance to contact and minimum distance to surface. Graphs can be created for comparing time, distance, load, power, torque, velocity, work and displacement. QForm RingRolling — is a special module of QForm V8 developed for wheel and ring rolling simulation. This program uses a variety of specialized techniques for this specialized process. For example, a dual finite element mesh method is used that increases the speed and accuracy of the simulation process.

QForm-Extrusion — is a stand-alone FEM program for metal profile extrusion simulation based on a combined Lagrange-Euler approach. It is possible to simulate extrusion of solid, semi hollow and hollow profiles. One of the features of QForm-Extrusion is the possibility to solve thermally and mechanically coupled problems of material flow and die deformation. This can be useful in simulations of cases where very slight inclinations of the bearing lead to changes in material flow characteristics.

QForm Extrusion Die Designer — is an automated system for 3D designing of a tooling set for profile extrusion. The program is developed as add-in for popural CAD system Ansys SpaceClaim. The program allows automated creation of 3D models from 2D drawings and also has a direct interface with the QForm-Extrusion program for completed dies to be use in extrusion process simulation. The program can automatically modify created objects by means of parametric design. = Application = QForm software can be used for simulation of hot and cold forging, open die forging, sheet forging, ring and wheel rolling, cross-roll piercing, cross-wedge rolling, orbital rolling, reducer rolling, profile extrusion etc...

Heat treatment simulation and microstructure forecast are realized as special QForm modules in cooperation with GMT mbH. By means of these modules, QForm allows simulating the processes of static and dynamic recrystallization as well as phase transformations for heat treatment processes such as heating, quenching and tempering.

QForm allows users to create their own subroutines with the Lua programming language. These codes can be used for prediction of various types of defects, tool life estimations and optimization. = Data preparation =

Geometry
A program called QShape is included for preparing 3D geometry for simulation in QForm. Its functions include geometry error correction and automated finite element mesh generation and optimization. Preparing and correction of 2D geometry models is carried out directly in QForm when importing geometry files.

Simulation parameters
The simulation set-up wizard is based on a question-answer principle that makes simulation easy for the user and doesn’t require special engineering knowledge. The process of simulation set-up consists of stages: operations chain, type of process, geometry, workpiece parameters, tool parameters, stop conditions, boundary conditions, blows parameters and special simulation parameters. QForm has its own built-in databases of deformed materials, tool materials, equipment drive types and characteristics, lubricants, friction parameters and simulation parameters. Users can also manually create any database item by specifying its parameters directly in the QForm program. The software also allows importing some data from third party files. = Technical support = Technical support for QForm users is provided directly from several locations worldwide including Moscow, England, Germany and Italy or via the team of local distributors. Support includes the supply of updated versions, bug fixes and consulting. = Language = QForm software and its documentation are available in English, Russian, Italian, German, Spanish, Chinese, Polish, Portuguese and Turkish. = Compatibility with third party software = QForm allows import and export of drawings and solid model between most CAD systems. Also it is possible to import into QForm the cast workpiece shape and calculated result fields of casting simulations from ProCAST and MAGMA casting simulation programs. Different materials and alloy properties such as flow stress curves can be imported from JMatPro. Finite element meshes can be imported from *.unv and *.ntl files exported from various finite element mesh generators. = Participation in benchmarks = QuantorForm Ltd. software always participates in different international conferences on benchmarks. The first important international benchmark test QForm participated in took part in 1994 in Baden-Baden, Germany. The latest benchmarks QuantorForm Ltd. software participated in are:
