Abstract

Abstract: Aiming at complex nonlinear dynamic behaviors of stone-cutting process with circular saw and handling large mesh deformation instability in FEM, according to brittle material fracture mechanism, an adaptive coupling algorithm was established for calculating the cutting process of circular saw-stone materials system. The results show that the material removal process is a process of intermittent cycle; the cutting force is zero at the beginning of the process, and the force increases rapidly when the blade contacts with the stone, then decreases, eventually varies in a stable fluctuation. According to von-Mises stress distributions of saw blade and stone, the easily damaged region is determined. Through comparison, it is found that the blades’ transverse vibration velocity simulation data are consistent with the experimental results.
