DEFINITION

Classification: 409/80

With sensing of numerical information and regulation without mechanical connection between sensing means and regulated means (i.e., numerical control):

(under subclass 79) Apparatus or method including detection of information on the separate member which information is of a prescribed magnitude and is other than a physical shape or outline, wherein the detected information is transmitted to the apparatus for performing the shaping operation by means other than a mechanical linkage.

(1) Note. This subclass is the home for milling combined with "numerical control" using a tape, card, etc., as the replaceable information supply.
