Abstract
This disclosure relates to an indexing feed mechanism for a cutting machine comprising an indexing vise for gripping a workpiece and moving it forward into a cutting position. The mechanism includes a lead screw interengaged with complementary means formed on a stopper means adapted to limit the rearward extent of the stroke of the indexing vise. Rotation of said screw will, therefore, cause translation of said stopper means thereby varying the rearward limit of travel of the indexing vise during its stroke. The lead screw extends from a rotatable shaft and means located at the operating station of the cutting machine are provided for rotating the shaft. The shaft is operably connected to a digital indicator which indicates in digital numerals the predetermined stroke of the indexing vise as a function of the angular position of the shaft.
