Class Vocabulary

Term	Definition
angular clearance	The enlarged section below the die opening that allows the blank to fall from the die.
blanking	A shearing operation that creates a hole in sheet metal by separating an interior section. The removed piece of metal is the desired part.
break off	A practical term for the rough, fractured ring surrounding the edge of a blank.
burnishing	The creation of a shiny, polished surface on metal due to a shearing action.
clearance	The space between the punch and the die that allows metal to be cut.
compressive force	A force or pressure that attempts to flatten or squeeze a material.
cut band	A practical term for the burnished ring surrounding the edge of a blank.
deflection	The misalignment of components due to various stresses.
deformation	The moment during which the punch penetrates the sheet and metal flows into the die opening. Deformation and penetration cause the edge radius and burnished ring.
double breakage	The condition of two separate deformation stages caused by insufficient clearance. Double breakage causes two burnished rings on the blank edge.
edge radius	A rounded edge on a blank caused by the initial deformation as the punch begins to enter the die.
fracture	The moment during which cracks form and the blank separates with a tearing action. Fracture causes the roughened break off section on the edge.
lubricant	A fluid designed to reduce friction and cutting forces during a stamping operation.
punching	A shearing operation that creates an open hole in sheet metal by separating an interior section. The removed metal section is discarded scrap.
shear strength	The ability of a material to resist forces that attempt to cause the internal structure of the material to slide against itself.
shearing	The cutting and separating of material without the formation of chips.
snap-through	The moment during which the blank separates from the sheet and compressive forces are released from the die components.
stripper	A plate designed to remove sheet metal stock from the punch as it pulls away from the die during the operation.
stripping	The moment during which the punch retracts from the die and is removed from the sheet.
taper	An angled surface that appears on the edge of a blank. Taper is the result of clearance between the punch and die.
tensile strength	The ability of a material to resist forces that attempt to pull it apart or stretch it.
