Developable Surface

• In mathematics, a developable surface is a
  surface that can be flattened onto a plane
  without distortion
• Many developable surfaces can be visualised as
  the surface formed by moving a straight line in
  space
• Developable surfaces that can be realized in 3D
  space are cylinders, cones, planes
• Spheres are not developable as they cannot be
  unrolled into a plane
• All developable surfaces are ruled surfaces
• Not all ruled surfaces are developable surface,
  hyperboloids are examples of ruled surfaces that
  are not developable

Developable Product Forms

• Straight ruled surfaces appears on many products
  formed by folding and bending sheet materials
• Skilful combination of ruled surfaces can make a
  mathematically simple developable surface looks
  as dynamic as very complex surface
• By introducing free-form curves and varying the
  matching endpoints, designers can introduce
  dynamism to the product form

Sheet Metal Forming

Bending

• Bending is a common manufacturing method to
  process sheet metal. It is usually done on a bend
  press (or break press), but also
  swing-bending-machines are used. Typical products
  that are made like this are electrical enclosures

Rolling

• Rolling is a fabricating process in which the
  metal, plastic, paper, glass, etc. is passed
  through a pair of rolls
• There are two types of rolling process, flat and
  profile rolling
• In flat rolling the final shape of the product is
  either classed as sheet (typically thickness less
  than 3 mm, also called "strip") or plate
  (typically thickness more than 3 mm)
• In profile rolling, the final product may be a
  round rod or other shaped bar such as a
  structural section (beam, channel, joist etc)
• Heavy plate tends to be formed using a press
  process, and is termed forming, rather than
  rolling

Roll Forming

• Roll forming is a continuous bending operation in
  which a long strip of metal is passed through
  consecutive sets of rolls, or stands, each
  performing only an incremental part of the bend,
  until the desired cross-section profile is
  obtained
• Ideal for producing parts with long lengths or in
  large quantities
• A variety of cross-section profiles can be
  produced, but each profile requires a carefully
  crafted set of roll tools

Activity Lamp-shade Design

• Design a new lamp-shade for IKEA DINGE, the
  design should be manufactured by cutting and
  folding PP plastic sheet
• Test your design on paper
• Cut your final design on card
