features, specific to machine tools, which relate to a requirement or problem of a nature which is not peculiar to a particular kind of machine tool, e.g. feeding work, which are covered by subclass Fulltext... Hierarchy... Expanded...B23Q, although the realisation of these features may differ according to the kind of machine tool concerned. The said subclass covers such features, in general, even if the feature or a specific function, in any particular case, is to some extent peculiar to, or is claimed only for, machine tools designed for one particular operation; only in exceptional cases are such features classified in the subclass for the machine tool concerned. Certain features of this general nature are, however, referred to subclasses relating to particular metal-working operations, especially Fulltext... Hierarchy... Expanded...B23B, in which case the subclasses in question are not restricted, in respect of those features, to the kind of machine tool with which they are primarily concerned.
In this class, the following terms or expressions are used with the meanings indicated:
"metal-working" covers the working of other materials unless the context requires otherwise;
"kind of operations" and similar expressions relate to such metal-working operations as boring, drilling, milling and grinding;
"kind of machine" means a machine designed for a particular kind of metal-working operation (e.g. a lathe);
"form of machine" means a machine of a particular kind adapted or arranged for a particular way of working or for particular work, e.g. face-plate lathe, tailstock lathe, turret lathe;
"different machines" covers different forms of machines for performing the same type of metal-working operation, e.g. vertical and horizontal boring machines.
If details, components, or accessories have no essential feature specific to machine tools, the more general class, e.g. Fulltext... Hierarchy... Expanded...F16, takes precedence.

Note(s)
In this subclass, groups designating parts of machine tools cover machine tools characterised by constructional features of such parts.
In this subclass, the following terms or expressions are used with the meanings indicated:
"controlling" means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation; [3]
"regulation" means maintaining a variable automatically at a desired value or within a desired range of values. The desired value or range may be fixed, or manually varied, or may vary with time according to a predetermined "programme" or according to variation of another variable. Regulation is a form of control; [3]
"automatic control" is often used in the art as a synonym for regulation. [3]
Members which are comprised in the general build-up of a form of machine, particularly relatively large fixed members (Fulltext... Hierarchy... Expanded...B23Q 37/00 takes precedence)
characterised by constructional features relating to the co-operation of relatively movable members; Means for preventing relative movement of such members [6]

Hierarchy... Expanded...B23B 47/00 takes precedence; safety devices in general Fulltext... Hierarchy... Expanded...F16P)

"copying" covers the derivation of a required shape from a pattern, of the same or a different shape or scale, by a mechanism or equivalent means controlled by a member following the pattern. The pattern may be a model or drawing, or an element such as a cam incorporated in the operating mechanism of a machine. This term does not cover the derivation of a required shape from simple geometrical shapes, e.g. generating a cycloid by a rolling circle, which in general is provided for in group Fulltext...
