Page 21 - Modular design for machine tools

Nomenclature

The contents of this book cover the modular design of machine tools to
a various extent, ranging from the engineering and methodology for
the modular design, through the joint stiffness, to the application of
the ultrasonic waves. As a result, we must be aware of the importance
of avoiding unnecessary confusion in the nomenclature. Thus, in this
book, the leading nomenclature has been determined in each part in full
consideration of that conventionally and widely used so far, and dupli-
cation has been eliminated as much as possible.
