Usually, the manufacturing of heavy parts with large thicknesses relies on the casting process. Because of the uniqueness and the dimensions of these parts, this process requires generally a large amount of time for preparing the dies and setting the filling arrangement to avoid as much as possible flaws through the thickness. Obviously, that kind of part is costly to produce. The purpose of this project is to develop an in depth expertise in a very promising process for manufacturing heavy hollow axisymmetric parts made in high strength steel. This process is the roll bending process. The major goals are to reduce the time and the cost of the manufacturing of large axisymmetric parts, without loosing accuracy and service life duration.

通常，具有大厚度的重型零件的制造依赖于铸造工艺。由于这些部件的独特性和尺寸，该工艺通常需要大量的时间来准备模具和设置填充装置，以尽可能多地避免贯穿厚度的缺陷。显然，这种零件的生产成本很高。该项目的目的是在一个非常有前途的过程中开发一个深入的专业知识，用于制造高强度钢制成的重型空心轴对称零件。该过程是辊弯过程。主要目标是在不降低精度和使用寿命的前提下，减少大型轴对称零件的制造时间和成本。
