AB - The paper deals with analysis of deformation processes and related aspects of the chip formation as the chip thickness, the chip ratio and the shear angle during turning hardened steel 100Cr6. This paper investigates influence of feed on the mentioned aspects through the metallographic analysis, calculation of the significant aspects of deformation processes and the following experimental study. This experimental study is based on application acoustic emission sensors. The results in this study reports that feed significantly does not affect such parameters as the chip ratio, deformation angle in the cutting zone. On the other hand, experimental study indicates that increasing of feed in hard turning causes increasing of the process instability and increasing intensity of deformation processes in the cutting zone.
