Based upon a survey of chip breakup information, the various methods have been evaluated for application to automated accurate turning systems. Many chip breaking methods work well on shafts or cylinders but fail to break chips for an entire inside or outside contouring cut. Many metals produce straight or snarled chip forms at small depths of cut, feed rates, or moderate surface speeds. These chip forms can be a cause of workpiece and tool damage. Such forms also interfere with on-machine gaging, part transfer, and tool change. Often the chip wraps around the tool holder and is difficult to remove even in manual operation. Computer analysis now makes it possible to get the most of each types of chip breaking system. Reliable ship breaking is urgently needed for automated systems, especially those operating in an unmanned mode.
