From page 31...
... Chapter 3, "Mass-Change Processes," discusses unit processes that remove or add material by mechanical, electrical, or chemical means. These processes include traditional chip-making processes such as shaping, turning, milling, drilling, sawing, and grinding, as well as nontraditional processes such as laser machining, electrodischarge machining and electrochemical machining.

From page 32...
... The opportunities for improvements to individual unit processes derive from the need to overcome specific technical limits and barriers to process performance. The resulting set of research recommendations provides the basis for identifying several key enabling technologies that support all unit process families and material classes.

From page 33...
... Novel processes may also provide a significant benefit in the processing of traditional materials, for example, nearnet-shape casting of steel into structural shapes. Unit processes should be designed for flexibility, so that variations in starting materials, initial conditions, and so on, can be accommodated without requiring substantial additional process development to produce a quality product.
