Abstract (en)

[origin: EP2745954A2] The method involves machining a workpiece (5) for forging process, which is arranged radially to forging tool (3). The machined workpiece in passed through different feed directions. The machined workpiece is inclined and is deformed with the mold surfaces of the forging tools depending on the passage of different feed directions. The workpiece along the feed direction is deformed against the sloping mold surface which is formed in opposite to the feed direction along forging axis (2) formed parallel to mold surface.
