DEFINITION

Classification: 407/13

RECTILINEAR BROACH:

(under the class definition) Device including a plurality of sequentially acting protuberances on each of which there is a cutting edge or point, adapted to move in a straight line with respect to the work so that a first protuberance makes a shaping cut into that surface of the work and is followed by a second protuberance which makes a deeper shaping cut into that surface of the work, so that the actions of sequentially acting protuberances is cumulative.

(1) Note. A rod-like cutter which moves along the axis thereof is considered to move in a straight line even if the cutter rotates to cut a helical groove.

(2) Note. The "protuberance" of this subclass may be blade-like extending across the lateral extent of the tool holder, may be ring-like extending entirely about the tool holder, or may be a single tooth, etc.
