... Radial forging machines, also referred to as rotary forging machines, are a modification of the traditional open-die press design that uses two sets of opposing dies, all of which apply deformation to the workpiece. Each pair of dies is arranged perpendicularly to the other as shown in Fig. 2 , which...
