.~ Work swings about progressively cutting tool during tool stroke
DEFINITION
Classification: 83/351
(under subclass 350) Device in which a work-feed means acts during the tool stroke upon a portion of the work spaced from the tool and in a direction not intersecting the cutting zone, whereby the work is caused to pivot about the portions thereof which are successively engaged by the tool, to effect a generally curved or irregular line of cut.
(1) Note. The action is similar to that of an operator using a pair of scissors to cut a curved piece out of tin or cardboard.
