WITH 100% CORRECT ANSWERS
LATEST VERSION 2025/2026.
Forging - ANS -applied stress exceeds workpiece's yield strength
-stronger and tougher parts than cast
forging types - ANS open die, impression/closed die, upset/ heading, piercing, coining
bulk deformation processes - ANS rolling, forging, extrusion, drawing, swaging
recrystallization temp - ANS used for 'hot rolling/forging' around 60% of melting temp
bulk deformation - ANS forging, swaging, rolling, extruding, drawing
swaging - ANS radial forging - internal and external shapes
rolling - ANS -high speed continuous parts
-reduces thickness (draft)

, extrusion - ANS -billet is forced through a die
-complex shapes in continuous production
-hot or cold
-tolerances to .25mm
drawing - ANS -material is pulled through a die
-for cross-sections smaller than extrusion
-less versatile than extrusion
barelling - ANS caused by friction in open die forging
open die forging - ANS friction against die causes barreling
impression die forging - ANS forces increase as die closes, cavity filled, flash is expelled
forge die design - ANS -dies usually made of high alloy or tool steel
-single part line, ideally flat
-draft angle 3-7º to allow part removal
cold rolling - ANS -strain hardening
-good tolerances (.1mm - .35mm)
- good surface finish
-outer grains altered
hot rolling - ANS -just above recrystallization temp
