The scientific activity of the Department of Metal Forming focuses on the development of modern metal forming technologies and the design of innovative technological processes and machines. Research conducted in the Department combines theoretical analyses, numerical simulations and experimental studies, making it possible to develop solutions with direct industrial applications.
One of the key research areas is the forming of preforms in the die forging process, where proper preparation of the input material significantly increases the efficiency and techno-economic performance of the production process.
Particular attention has been given to the cross-wedge rolling (CWR) method, with analyses of the state of stress and strain in the material as well as the factors determining process stability.
As part of this work, methods were developed to enable the optimal selection of tool geometry parameters, and a laboratory research rolling mill was designed and built to carry out experimental analyses of the rolling process.
Research conducted in the Department includes the development of technologies for forming hollow products using methods such as:
An important area of research concerns the forming processes of aluminium alloy forgings. A comprehensive analysis of die forging at low deformation levels was carried out, making it possible to determine key technological parameters such as critical reduction.
Research is also conducted on forming technologies for hard-to-form non-ferrous metal alloys, in particular magnesium and titanium alloys, which are widely used in the aerospace industry.
One of the interesting research directions is the development of a technology for manufacturing steel balls from scrapped railway rails.
The processes used include:
This technology enables the effective use of recycled material, increases production efficiency and improves the quality of large-diameter balls.
The Department conducts research on the forming processes of axisymmetric forgings, including upsetting with torsion and orbital forging.
Technological benefits:
These processes are characterised by complex material flow kinematics and require advanced numerical modelling.
The development of the theory of these processes constitutes a significant contribution to the advancement of knowledge in the field of metal forming.
An important element of the Department’s research activity is the design and construction of machines for metal forming.
The results of research conducted in the Department are published in numerous scientific journals and specialist monographs. The scientific output includes publications produced continuously for many decades and constitutes a significant contribution to the development of global knowledge in the field of metal forming technology.
