DEFINITION

Classification: 83/13

(under the class definition) Method which includes a step of cutting.

(1) Note. A step of cutting, as herein applied, consists in moving a tool and work into contact with and relative to each other such that the tool moves entirely through the thickness of the work. Once the cut through the wall thickness has been achieved, then, an interruption of said relative movement, or of cutting contact extending throughout said wall thickness, shall be construed as a termination of said "step".

(2) Note. A special exception to the limitations expressed in these definitions (i.e., the limitations which require a moving tool and/or an edge backup member) exists in the case of wherein sound waves (e.g., supersonic sound) cause work to be cut through its thickness. Such a step will be proper for this class and this subclass as a process of cutting.
