磨削加工是实现精密和超精密加工的重要手段。磨削过程中砂轮不平衡引起的振动对工件表面质量有很大影响。然而，在大多数研究中，砂轮表面形貌和/或砂轮与工件之间的相对振动的影响没有被考虑。考虑砂轮与工件之间的相对振动，结合磨粒轨迹方程，建立了磨削过程表面形貌分析与仿真模型。首先研究了砂轮表面形貌模型，然后提出了一种新的磨削过程表面形貌仿真模型。最后通过实例分析，讨论了砂轮振幅、砂轮粒度以及磨削参数对表面波纹度和粗糙度的影响。仿真结果可用于优化实际磨削过程，提高磨削表面质量或通过给定的磨削参数预测表面形貌。
Grinding is an important means of realizing precision and ultra-precision machining. Vibration caused by an unbalanced grinding wheel in grinding process has a significant impact on the quality of workpiece surface. However, the effect of wheel surface topography and/or the relative vibration between grinding wheel and workpiece are not considered in most researches. Taking the relative vibration between grinding wheel and workpiece into account, alongside the abrasive grain trajectory equation, a new analysis and simulation model for surface topography of the grinding process is established. The model for the topography of the grinding wheel surface is first studied, and subsequently, a new simulation model for surface topography of the grinding process is proposed. Case studies are performed at the end, and the influence of grinding wheel vibration amplitude, wheel grit number, as well as grinding parameters on the surface waviness and roughness is discussed. The simulation results could be used to optimize the actual grinding process to improve the ground surface quality or predict the surface topography by given grinding parameters.
