Forging allowance

The machining allowance should allow for the worst-case buildup of draft and for all tolerances. Extra metal should be provided to at the critical machined surfaces away from the grain-flow pattern that occurs in the flash region near the parting line. Generally the machine allowance should be .06 inch for each … See more The mating surfaces of the two halves of the die define a parting line around the edges of the forging as they come together. Determining the position of the parting line is a critical step in the forging design. The parting … See more The forging must be designed such that adequate draft is present to facilitate removing the forging from the dies.

WebForging alloys purchased in these forms are equivalent in cost to similar alloys used for castings, bar or plate stock. Purchased raw material must include allowances for punch-outs, flash, other discards and machining allowances. The amount varies with the forging process and part design. WebThe allowance for machining of forging depends on its size and shape, relative length in proportion to width and thickness, number of holes and pockets, and grade of material being forged. It varies from 0.75 mm (for small forgings about 1.25 kg in weight) to about 1.4 mm minimum (for large forgings weighing 50—100 kg).
