DFMA & C• Design for Manufacturing (DFM) :

Entails making parts easier to produce new raw stock• Minimize complexity of manufacturing.• Use common axes and common processes.

• Design for Assembly (DFA) :entails making attachment methods simple

• Minimize number and complexity of assembly operations.• Individual parts may be more complex in design.

•Cost : Concern with reducing overall part production cost. Concern with reducing product assembly cost

DFMA & C GIDELINES

• Reduce the part count.• Use modular designs.• Optimize part handling.• Assemble in the open.• Do not fight gravity.• Design for part identity.• Eliminates fasteners.• Design parts for simple assembly.• Reduce simplify & optimize manufacturing process.

Fastening

• Consider the least expensive fastening method that meets the requirements

APPLICATION : TWEEL TYREInvented by Michelin US tyres and researching on it.

MANUFACTURINGStiff hub :• It is made by aluminium and using casting processSpokes :• It is made by Polyurathane material which is always retains its

form and its flexible.• It is manufactured by molding method.Sheer Band:• Made by polymer & manufactured by molding method.ASSEMBLY• Tweel is a combination of wheel and tyre.• It’s a single unit so wheel assembled during manufacturing.COST• overall tyre cost reduced because of no machining and no

assembly required.

ADVANTAGES

• No tube and tyres required.• No puncture.• Tyre life is more.• Assembly time reduces.• One time investment .• Tyre run on any type of road.• It does not need air.• Three times long life.• The tread can be replaced without having to replace the

entire unit, so there is less waste of material.

APPLICATIONS

• Golf cart.• Bulldozer.• Military vehicles.
