1A Drawing (Task 16)

Sheet Metal and Development Drawings

Sheet Metal is everwhere !

Sheet Metal Basics

• Material– Steel, Brass, Aluminium– Typically 0.6 – 2.5mm

• Limited distortion capabilities

• Allowance for distortion

BendingThe minimum bend radius is determined by the type of material, thickness and the equipment available. Good compromise is r(min) = t

In a bend material is distorted and allowance has to be made. For general purposes the `Neutral line’ is used to calculate the ` Bend Allowance’

Bend Allowances

Bend/Corner Relief
