Forging is the process by which metal is heated and is shaped by plastic deformation by suitably applying compressive force. Usually the compressive force is in the form of hammer blows using a power hammer or a press.

Forging refines the grain structure and improves physical properties of the metal. With proper design, the grain flow can be oriented in the direction of principal stresses encountered in actual use. Grain flow is the direction of the pattern that the crystals take during plastic deformation. Physical properties (such as strength, ductility and toughness) are much better in a forging than in the base metal, which has, crystals randomly oriented.

Design Consideration
Parting surface should be through the centre of the part, not near the upper or lower edges. If the parting line cannot be on a single plane, then it is good practice to use symmetry of the design to minimize the side thrust forces. Any point on the parting surface should be less than 75º from the principal parting plane.

As in most forming processes, use of undercuts should be avoided, as these will make the removal of the part difficult, if not impossible.

Recommended draft angles are described in the following table.

Material	Draft Angle (º)
Aluminium	0 – 2
Copper Alloys (Brass)	0 – 3
Steel	5 – 7
Stainless Steel	5 – 8

Tolerances
- Dimension tolerances are usually positive and are approximately 0.3 % of the dimension,   rounded off to the next higher 0.5 mm (0.020 in)
- Die wear tolerances are lateral tolerances (parallel to the parting plane) and are roughly +0.2 %   for Copper Alloys to +0.5 % for Aluminium and Steel
- Die closure tolerances are in the direction of opening and closing, and range from 1 mm (0.040   inch) for small forgings, die projection area < 150 cm² (23 in²), to 6.25 mm (0.25 inch) for large   forgings, die projection area > 6500 cm² (100 in²)
