Abstract
In a machine for cutting grooves of a given pattern through a blank with a fret saw blade, openings for receiving the fret saw blade at the cutting starting points of the grooves are determined such that the center of each opening is positioned at a point spaced from a cutting start point by a distance equal to one half of the width of the fret saw blade in a direction opposite to the direction of cutting the groove.
