Three-dimensional modeling method of surface morphology of parallel diamond grinding wheel

Abstract

The invention discloses a three-dimensional modeling method of the surface morphology of a parallel diamond grinding wheel. The method comprises the steps of defining a parallel diamond grinding wheelmodel and an abrasive grain model, calculating an average space of the abrasive grains according to the surface morphology of a grinding wheel and a grinding wheel concentration, carrying out cube mesh division on the grinding wheel and establishing a cube virtual lattice, carrying out spherical abrasive grain initial positioning in the center of a cube such that spherical abrasive particles randomly move in the virtual lattice, replacing the spherical abrasive particles with defined actual abrasive grains and carrying out turning of different directions to realize direction offset, definingthe surface of a bonding agent to obtain a plate-shaped grinding wheel surface morphology model, and carrying out circular bending on the plate-shaped grinding wheel surface morphology model to obtaina parallel diamond grinding wheel surface morphology model. According to the method, multiple shapes of abrasive particles are used, an abrasive grain size, an abrasive grain distance and abrasive grain distribution are considered to establish the grinding wheel surface morphology model, the model is more close to the actual parallel diamond grinding wheel surface morphology, and the grinding performance and result of the grinding wheel can be accurately evaluated and predicted.

Description

technical field [0001] The invention relates to the field of simulation of the surface topography of a grinding wheel, in particular to a three-dimensional modeling method for the surface topography of a parallel diamond grinding wheel. Background technique [0002] Grinding can be regarded as the cutting process of a single abrasive grain at the microscopic level, and it can be regarded as the overall effect of the cutting process of a large number of abrasive grains discretely distributed on the surface of the grinding wheel at the macroscopic level. Due to the large number of abrasive grains on the surface of the grinding wheel, the shape, size, position, and angle of the cutting edge are random and diverse, the high-speed movement of the grinding wheel, and the variation of grinding process parameters make the grinding process extremely complicated, and it is difficult to conduct a comprehensive grinding wheel and workpiece. The measurement and monitoring of state change...
