Radial forging for the manufacture of ball screw actuator shafts

A method of manufacturing a tubular component, comprising:

• performing a first radial forging operation on a workpiece, the workpiece including a bore along a longitudinal axis extending from a first end to a second end opposite the first end, the first radial forging operation comprising:
• holding the workpiece at the second end;
• and
• radially forging at least a portion of a first region proximal to the first end of the workpiece from a first outer diameter to a smaller second outer diameter;
• performing a second radial forging operation on the workpiece, the second radial forging operation comprising:
• holding the workpiece at the first end;
• and
• radially forging at least a first portion of a second region of the workpiece from the first outer diameter to a smaller third outer diameter, the second region extending from the second end to a third region adjoining the first region;
• and
• performing a third radial forging operation on the workpiece, the third radial forging operation comprising:
• holding the workpiece at the first end;
• and
• radially forging at least a second portion of the second region of the workpiece from the third outer diameter to a smaller fourth outer diameter.
