“…e results showed that the workpiece surface roughness increases with the increase of the depth of cut and the workpiece surface roughness increases and then decreases with the increase of ultrasonic amplitude. Zhao et al [21] investigated the effect of grinding direction on the characteristics of the surface of the prism plane sapphire. e results showed that the force was greater in the c-axis which was corresponding to the greatest surface damage.…”

This article presents a new model of the flat surface grinding process vibration conditions. The study establishes a particular analysis and comparison between the influence of the normal and tangential components of grinding forces on the vibration conditions of the process. The bifurcation diagrams are used to examine the process vibration conditions for the depth of cut and the cutting speed as the bifurcation parameters. The workpiece is considered to be rigid and the grinding wheel is modeled as a nonlinear two-degrees-of-freedom mass-spring-damper oscillator. To verify the model, experiments are carried out to analyze in the frequency domain the normal and tangential dynamic grinding forces. The results of the process model simulation show that the vibration condition is more affected by the normal component than the tangential component of the grinding forces. The results of the tested experimental conditions indicate that the cutting speed of 30 m/s can permit grinding at the depth of cut up to 0.02 mm without sacrificing the process of vibration behavior.
