摘要

加工中表面形貌的生成是一个复杂的过程，是机床动力学和切削过程运动学相结合的过程。建立车削过程表面形貌仿真模型的目的是预测刀具几何形状、工艺参数和刀具-工件相对振动的综合影响。仿真结果表明，一个振动频率可以在工件轮廓上产生多个波长。将机床振动与表面形貌的相关性应用于圆柱车削加工中导致表面质量差的机床缺陷的准确诊断。

Influence of a Single Machine-Tool Vibration on the Workpiece Waviness Profile in Turning

The generation of the surface topography in machining is a complex process whereby the dynamics of the machine-tool and the kinematics of the cutting process are combined. The purpose of developing a surface topography simulation model in turning is to predict the combined effect of the tool geometry, process parameters, and relative tool-workpiece vibration. The simulations demonstrate that a single vibration frequency can generate multiple wavelengths on the workpiece profile. The correlation between machine-tool vibrations and surface topography is applied to accurately diagnose the machine defect that results in poor surface quality in a cylindrical turning process.
