Happy New Year 2021!

Several key features of upcoming QForm version in 2021

QForm API
     New QForm API (Application Programming Interface) allows users to create code to control QForm externally for analysis and automated optimization of technological processes. The pieces of code to control functions and parameters within QForm are automatically generated by our dedicated API constructor based on principles of visual programming, and they just need to be copied to the user's program of choice.

     This automatic code generation speeds up development applications and eliminates common errors. QForm API now works for C++, C#, Phyton and Visual Basic programming languages and more will be added in the future.

QForm for Linux operating system
     A new client-server version allows QForm use on servers with Linux operating systems. This special QForm Server solver can be installed on a Linux computer including High Performance Computing (HPC), so that the calculations are run on the Linux server while the users work with a standard QForm client on a Windows 7/8/10 computer or laptop. The data exchange between the server and client can be either through a local network or the Cloud.​​​​​​

Thermal simulation of the tools in multiple forging cycles
     Usually, in the simulation of bulk metal forming, we consider the temperature change of the die for just the current forming cycle. Before the simulation, the tool temperature is set to some single value that can be estimated for the die surface and the thermal transfer is calculated during the simulation for just the current forging operation. Meanwhile, in some cases of precise forging, it is necessary to know the accurate temperature distribution of the tools in a production situation, taking into account the heating of the tools due to contact with hot workpieces in a series of forging cycles when the temperature of the tools increases from one blow to the next until it reaches a quasi-steady-state nonuniform distribution. A special feature to simulate such multiple cycles of heating of the tools has been developed in the new version of QForm. This kind of simulation is relatively fast because only the thermal task is calculated for the specified number of forging cycles.

     In addition to improved material flow calculations due to more accurate temperature data, implementation of this feature in hot forging operations means that the estimation of tool fatigue failure becomes more accurate because it depends on the actual temperature distribution in a production setting. In cold forming operations, the cycling heating option allows more accurate calculation of actual tool dimensions due to thermal expansion that may influence finish product dimensions.
