Explain rules for designing castings?

Submitted by: Murtaza

☛ To avoid the concentration of stresses sharp corners and frequent use of fillets should be avoided.
☛ Section thicknesses should be uniform as much as possible. For variations it must be done gradually.
☛ Abrupt changes in the thickness should be avoided at all costs.
☛ Simplicity is the key, the casting should be designed as simple as possible.
☛ It is difficult to create true large spaces and henceforth large flat surfaces must be avoided.
☛ Webs and ribs used for stiffening in castings should as minimal as possible.
☛ Curved shapes can be used in order to improve the stress handling of the cast.
