DEFINITION

Classification: 72/77

With tool surface orbiting around axis parallel to direction of travel of longitudinally moving work:

(under subclass 67) Subject matter wherein the work moves in the direction of its greatest dimension (i.e., lengthwise), and the tool* turns about a center of rotation that is parallel to the direction of work movement, whereby any specific portion of the tool face* travels helically relative to the surface of the work.
