CADM Cheat Sheet (DRAFT) by

computer-aided design and manufacturing

This is a draft cheat sheet. It is a work in progress and is not finished yet.

UNIT !

product life cycle begins with the need of customer's and market's demands.
the two main processes include design and manufa­ctu­ring.
sub process of design includes sythesis and analysis and sub process of manufa­cturing includes process planning and produc­tion.

product life cycle image

phases in product cycle

design phase
manufa­cturing phase
philos­ophy, functi­onality and uniqueness of the product falls under synthesis
the backbone of manufa­cturing is process planning as it attempts to determine the most efficient sequence to produce the product
during synthesis the design takes the form of sketches or 3d repres­ent­ation to show the relation between various product parts.
the panner works with blueprints from the design team and may commun­icate to clarify changes in the design to fit manufa­cturing methods
analysis begins in an attempt to put the concept into the context of engine­ering science applic­ation to evaluate the perfor­mance of the product and it is achieved by modelling and simula­tion.
outcome of process planning is production plan, tools procur­ement, material order and machine progra­mming
the outcome of analysis and design is the design docume­ntation in the form of engine­ering drawings
once the PP is complete the production starts. the parts are inspected for quality stds requir­ements, assembled, packed, labeled and shipped
market feedback is usually done under the design process, with this feedback the product loop cycle is closed.
 

design process

it is the formul­ation of plan to help an engineer to build a product.
the fundam­ental elements of design includes, establ­ishment of objectives and criteria, synthesis, analysis, constr­uction, testing and evalua­tion.

presen­tation
engine­ering design is a multistep process including the research, concep­tua­liz­ation, feasib­ility assess­ment, establ­ishing design requir­ements, prelimery design, production planning, and tool design and enters the reprod­uction phase.
