DefinitionClass 408 is the residual locus of methods and machines for penetrating material, without substantial reshaping flow of such material, by means of a solid tool that turns about an axis, and moves relative to a workpiece, along that axis during operation. (1) Note. The phrase "without substantial reshaping flow of such material" is intended to cover the noncutting deformation of material by forcing a tool into or through said material, which method 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 cutting as defined above; however, not all classes have now been screened for such art. Included among such classes likely to include patents proper for Class 408 and not yet screened are Classes 82, 142, 409, and 451. SCOPE OF THE CLASS Class 408 is an elemental or basis class. That is, its subject matter is restricted (so far as possible) to means for, or steps of, accomplishing the following functions; cutting something (the "work"); or cutting, and handling the work to be cut; or cutting and handling the product of the cutting operation. |
