- Abstract:
- The reliability of machining operations is an essential requirement of modern automatic manufacturing system. In the machining operations, in which unbroken chips are the major obstacles for automation, reliability implies chip control as a major aspect. To improve chip control is necessity for automated machining. In turning operation chip control is difficult especially for mild steel because chips are continuous. Chip control is closely related to the chip flow and it plays also a predominant role in the effective control of chip formation and chip breaking for the easy and safe disposal of chips, as well as for protecting the surface-integrity of the workpiece. Although the chip flow direction plays an important role in the chip control and a way to calculate the chip flow angle in a wide range of cutting conditions has been subjected in some papers by several researchers, it has not been established satisfactorily yet. Obviously, to predict the chip flow direction is becoming an important subject for the development of suitable chip breakers and the automation of turning operations. In this study, using different indexable inserts and cutting conditions for turning of mild steel, the chip flow directions were measured and a new empirical formula for prediction of the chip flow direction in term of the tool cutting edge geometry and cutting conditions was obtained by using of mathematical statistics.
