DEFINITION

Classification: 409/316

With work infeed and means to arcuately reposition the work:

(under subclass 313) Apparatus including a base intended to support the apparatus against gravity, including structure to cause the workpiece to move relative to the base and relative to the cutting edge of the cutting tool to effect the shaping operation, and including means to cause the workpiece to additionally move along a curved path relative to the base and relative to the cutting tool to relocate the path of the cutting action with respect to the workpiece, so that a series of cutting passes yields an arcuate surface on the workpiece.
