The angle of the surface at the parting line from the primary parting plane should not exceed 75 o, in general, much shallower angles are preferred. It can be located such that one die half will be completely flat, and the line will surround the largest projected area of the piece. It is preferable that the parting line lie in one plane perpendicular to the axis of the die motion. The parting line should be indicated on the forging drawing. Determining the position of the parting line is a critical step in the forging design. The mating surfaces of the two halves of the die define a parting line around the edges of the forging as they come together. As a general rule, the rib thickness should be equal to or less than the web thickness to avoid process defects. Rib height forging manufacturing design - the ratio of rib height (H) to thickness (T) in general should not exceed 6:1. Design For Forging Manufacturing Considerationsįorging Manufacturing Design Considerations: For parts manufactured by forging that are produced in two-part impression dies, the designer should take into account the following: the parting line, the draft, the presence of ribs, bosses, webs, and recesses, and the machining allowance.
