DEFINITION

Classification: 72/190

Including orbitally moving tool-face:

(under subclass 184) Subject matter wherein the tool face travels in a closed loop path.

(1) Note. If a tool face travels along a path during deformation and returns along the same path during an "idle" (nondeforming) movement, the path is not a "loop" therefore a patent disclosing such an operation would be placed in another subclass within this group of subclasses.
