ABSTRACT A machine is provided for cutting oval shapes in planar workpieces, wherein the blade is dynamically oriented so as to maintain its cutting axis constantly tangent to the line of cutting. It utilizes a pivotably mounted cutter head, to which is attached an orienting arm that is arcuately recipro- cated by an element moving unidirectionally in a circle, the direction of circular movement being opposite to that in which the cutting head proceeds.
