Section 1.6 Selection of Manufacturing Processes

Forming and shaping (Figs. I.6b through I.6d): Rolling, forging, extrusion,
drawing, sheet forming, powder metallurgy, and molding (Part III).
Machining (Fig. I.6e): Turning, boring, drilling, milling, planing, shaping,
broaching; grinding; ultrasonic machining; chemical, electrical, and electro-

chemical machining; and high-energy-beam machining (Part IV). This broad
category also includes micromachining for producing ultraprecision parts
(Part V).
Joining (Fig. l.6f): Welding, brazing, soldering, diffusion bonding, adhesive
bonding, and mechanical joining (Part VI).
Finishing: Honing, lapping, polishing, burnishing, deburring, surface treating,
coating, and plating (Chapters 26 and 34).
Microfabrication and nanofabrication: Technologies that are capable of pro-
ducing parts with dimensions at the micro (one-millionth of a meter) and
nano (one-billionth of a meter) levels; fabrication of microelectromechanical
