DETAILS, COMPONENTS, OR ACCESSORIES FOR MACHINE TOOLS, e.g. ARRANGEMENTS FOR COPYING OR CONTROLLING (tools of the kind used in lathes or boring machines B23B 27/00); MACHINE TOOLS IN GENERAL CHARACTERISED BY THE CONSTRUCTION OF PARTICULAR DETAILS OR COMPONENTS; COMBINATIONS OR ASSOCIATIONS OF METAL-WORKING MACHINES, NOT DIRECTED TO A PARTICULAR RESULT
NOTE
-
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;
- "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;
- "automatic control" is often used in the art as a synonym
for regulation.

Attention is drawn to the Notes following the title of class B23.

NOTE
-
In groups B23Q 1/44 to B23Q 1/62, the following expressions are used with the meaning indicated:- "sliding pair" means a pair consisting of two elements operating in such a way that only straight line movement between both elements is possible;-"rotating pair" means a pair consisting of two elements operating in such a way that only rotary movement between both elements is possible;- "screw pair" means a pair consisting of two elements operating in such a way as to produce simultaneous rotation and axial translation between both elements.

In groups B23Q 1/44 to B23Q 1/62, where more than one pair of elements is provided on the same axis for the same kind of movement, the pairs are regarded as a single pair for the purposes of classification.

Copying
NOTE
-
In groups B23Q 33/00 or B23Q 35/00, the following term is used with the meaning indicated:- "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 B23Q 27/00
