1. 1A Drawing (Task 16) Sheet Metal and Development Drawings

2. Sheet Metal is everwhere !

7. Sheet Metal Basics Material – Steel, Brass, Aluminium – Typically 0.6 – 2.5mm Limited distortion capabilities Allowance for distortion

8. 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’

9. Bend Allowances

10. Bend/Corner Relief
