WebThread rolling is a type of threading process which involves deforming a metal stock by rolling it through dies. This process forms external threads along the surface of the metal stock. Internal threads can be formed using the same principle, specifically termed thread forming. In contrast with other widely used threading processes such as ...
WebRolled threads are formed by rolling the reduced diameter (approximately equal to the pitch diameter) portion of the shank between two reciprocating serrated dies. The dies apply pressure, compressing the minor diameter (thread roots) and forcing that material up to form the major diameter (thread crests). Webd 1 = Minor diameter, external. D 1 = Minor diameter, internal. d 2 = Pitch diameter, external. D 2 = Pitch diameter, internal. The effective diameter of the screw thread; approximately half way between the major and minor diameters. Lead angle (helix angle) The lead angle, φ, (helix angle) is dependent on and related to the diameter and the ...
