摘要 基于坐标矩阵的齐次变换和矢量运算法则,建立了铣削加工过程中刀具的运动轨迹方程,并在工件离散、刀具离散和加工过程离散的基础上,设计了铣削表面形貌仿真算法,并基于MATLAB的GUI功能开发了铣削加工表面形貌仿真系统。验证结果表明,仿真结果与实验结果一致性程度高,可应用于实际铣削加工表面几何形貌的预测和分析之中。 Tool path equation during the milling process is established based on the principles of homogeneous transformation and vector operation of the coordinate matrix.Simulation algorithm for milling surface topography is designed on the basis of discrete workpiece,discrete tool and discrete work process and a simulation system for milling surface topography is developed by applying GUI functions in MATLAB.Verification results indicate that the simulation results and the experimental results are basically identical,they can be applied to practical milling process to predict and analyze the geometrical topography of the milled surfaces.
