In this paper, a multiple data dependent systems (MDDS) method is proposed to analyse the localised variation of cutting dynamics in single point diamond turning (SPDT). The metal cutting dynamics are characterised by the natural frequency, the damping ratio, and the relative contribution of the central wavelength components which make up the roughness profiles at a finite number of radial sections of the workpiece. The characteristics of these wavelength components are correlated to different surface generation mechanisms. A series of cutting tests was carried out with different cutting conditions and materials being cut. Experimental results indicate that the cutting dynamics are dominated by the relative tool-work vibration and the swelling of the work materials. The contribution and the natural frequency of the tool-work vibration components are found to vary with the crystallographic orientation of the workpiece. These localised variation of cutting dynamics are shown to be caused by materials induced vibration which is inherent in the cutting system for a work material.
