Abstract (en)

Aspects of the present invention relate to a method (100; 200) of controlling a mandrel-free spinning apparatus (10) to produce an article, having a target geometry (40), from a workpiece (14), the mandrel-free spinning apparatus (10) comprising: a rotatable mounting point (4) for the workpiece (14); a first forming tool (12a); and a second forming tool (12b); the method including: whilst the workpiece (14) rotates, moving the first forming tool (12a) so as to: engage a first surface (16) of the workpiece (14); and urge the workpiece (14), from an initial workpiece geometry, towards and beyond the target geometry (4) into an intermediate geometry (120); and whilst the workpiece (14) rotates, moving the second forming tool (12b) so as to: engage a second surface (18) of the workpiece (14), opposed to the first surface (16) of the workpiece (14); and urge the workpiece (14) from the intermediate geometry (120) towards the target geometry (40).
