DEFINITION

Classification: 409/199

Machining arcuate surface:

(under subclass 183) Apparatus wherein the movement of the cutting tool with respect to the workpiece is such as to give the workpiece a curved surface.

(1) Note. To be proper for this subclass, the device must bring about the arcuate characteristics to the workpiece by relative movement of the work and cutting tool rather than by the arcuate shape of the cutting tool.
