ABSTRACT

In manufacturing, forming and removing are the two primary processes. Forming creates an original shape from a molten mass, a gaseous state, or solid particles. During such processes, cohesion is created among individual particles; examples include plastic molding, thin film metal deposition by evaporation or sputtering, and electroforming. Removing processes destroy cohesion among particles as exemplified in wet chemical etching, electrical discharge machining (EDM), sometimes referred to as

electrodischarge machining,

traditional mechanical turning, and laser drilling.
