Chip breaking and control is essential to automatic operation of precision turning systems. Failure to transfer parts and system jams can occur if chip fragments are not continuously removed. Surface damage and tool breakage also result from chips that are permitted to wrap around the tool. Also, with increasing environmental concerns, chip handling and recycling are becoming major issues in manufacturing. New information on a variety of mechanisms for breaking chips and methods for removal from the system are discussed. Some of the chip breaking methods are evaluated for the range of cutting in which they are effective. Chip curl and chip breaking analyzed carefully by Nakayama and others is expanded to more fully understand the ways in which chips can be broken. 23 figs.
