Design for Manufacturability

A good product not only met the customer’s needs in terms of function. It also had to be efficiently and economically manufacturedAttitude :

Traditional attitude : « we designed it, making is your problem »DFM attitude : « let’s design it so that it works, and can be efficiently produced »DFM teams comprised of : design, drafting, manufacturing

Reduce Cost : Metal Tech Manufacturing co (MTM) production cost fall by 32 percent and sales doubled within a year

Use of Hidden line:Hidden lines should always start and end with a dash Dash should always join at corners

Except:When such a dash would form a continuation of a visible detail line

Advantage of sketchingRequires very view materials :

pencil/pen, media (paper/graph paper or even napkins)Eraser

Quick

Do you know ?Early design of Voyager around the world A/C was sketched on napkins

General rules skechingHold the pencil firmly, but not so tightly as to create tension or hand fatigueGrip the pencil approx one inch to one and one-half inches up from the pointMaintain a confortable angle between the pencil and the sketching strokesDraw horizontal lines from left to right using short, slightly overlapping strokesDraw vertical lines from top to bottom using short, slightly overlapping strokesDraw curved lines using short, slightly overlapping strokes

Proportion in sketchingUse graph paper whenever possibleExamine the object and mentally break into its componentsBegin with the largest component, estimate the proportionUse construction line squares and rectangles to block in irregularly shaped components
