... A recent text that presents a valuable discussion of the many factors involved in equipment design is Slocum's Precision Machine Design (Slocum, 1992~. A case can be made for the importance to domestic manufacturers of high-quality, locally produced processing equipment rather than reliance on foreign suppliers.

... The end result would be worldclass unit process equipment available at a competitive sales price with low lifecycle costs. However, the committee suggests that the greatest research need in the area of equipment design is the interaction of process equipment manufacturers with one another and with university research, national laboratories, and other government agencies to identify needs that are broader and more long-range than those the committee has identified for the other five enabling technologies or in this section on equipment design.

... For example, taking heavy machining cuts with nonideal coolant application and poor cutting tool conditions can result in self-induced "chatter" in the tooling and workpiece, often resulting in poor surface quality condition and dimensional variations in the machined part. Also, equipment designs that minimize thermal distortion due to nonunifonn temperature variation that is caused by internal and external heat sources are needed so that the equipment can maintain positional accuracy during all phases of equipment operation.

... Considerations that override all others are to develop equipment that is safe to operate and imposes no harmful effect on the workers or environment.
