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
Bending The 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
