Description
Class 408 is the residual locus of methods and machines forpenetrating material, without substantial reshaping flow of suchmaterial, by means of a solid tool that turns about an axis, andmoves relative to a workpiece, along that axis during operation.
(1)Note. The phrase "without substantial reshaping flowof such material" is intended to cover the noncutting deformationof material by forcing a tool into or through said material, whichmethod or apparatus is provided for in the class for Metal Deforming(see References to Other Classes, below).
(2)Note. Class 408 is intended to ultimately include all cuttingas defined above; however, not all classes have now been screenedfor such art. Included among such classes likely to include patentsproper for Class 408 and not yet screened are Classes 82, 142, 409,and 451.SCOPE OF THE CLASSClass 408 is an elemental or basis class. That is, its subjectmatter is restricted (so far as possible) to means for, or stepsof, accomplishing the following functions; cutting something (the "work");or cutting, and handling the work to be cut; or cutting and handlingthe product of the cutting operation.
