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
Question 16
• Introduction to the Sheet Metal Module of Pro/Engineer
• Simple bend & bracket• Additional flaps/tabs and bends• 2-D developments
• Conversion from Solid model to Sheet(IDP Chassis)
• 2-D layout
To Pro/Engineer
