QForm 3D - major areas of application and features
Major areas of application
QFORM3D software was developed in 2002 by QuantorForm Ltd. as an extension of QFORM2D. The software combines 2D and 3D simulation and it retains the easy interface from QFORM2D. For 3D simulations you simply select “solid body models” for the dies and the workpiece as the initial geometry data. QFORM3D is used for the simulation of hot, warm and cold forming processes. The software predicts material flow defects, identifies the temperature distribution, and calculates the load and consumption of energy for the deformation.
QFORM3D combines 2D and 3D simulation in a single software package that gives an enormous advantage to the user. The software has retained the broad functionality and the ease of use of its 2D predecessor. The only thing required in order to convert to a 3D simulation is to select “solid body models” for the dies and the workpiece, instead of the 2D cross-sectional contours required for 2D. All other data are specified in the same fashion as for the 2D simulation, using a convenient Data Preparation Wizard to minimize the probability of data entry errors. The integration of 2D and 3D simulation in the same software package provides a unique opportunity to efficiently simulate processes consisting of several forging impressions, the first of which is axially symmetrical and can be solved quickly in a 2D setting (e. g. upsetting) and the subsequent impressions which require full-scale 3D simulation. The object-oriented software structure creates a very comfortable and fully integrated user environment. The data preparation can be visually monitored and the computation is accompanied by the simultaneous graphic display of the results. Thus the software is an efficient tool for the computer assessment of the process, which is much more economical and faster than the debugging of the technology by hit and miss. The software supports the import of IGES and STEP files, which avoids a loss of accuracy typical in STL format files used by other simulation packages. Surface models of the dies created by PowerShape (Delcam Plc) also can be effectively imported to QForm. Using the full and accurate die and workpiece geometry as the initial data and also having the expertise of non-linear approximation for the solution of 2D problems, QFORM3D was the first commercial software to use quadratic finite element approximation in order to solve 3D problems. This allowed a considerable increase in the solution accuracy, a reduction in the loss of volume and a high solution reliability and certainty for forging flaws prediction. The description of surfaces by the non-linear finite element model allows remeshing as often as needed, without ‘shouldering’ the surface at tight curves, which is characteristic of linear elements.
