摘要
根据数控车削加工的特点,提出一个基于构造单元的工件分解表达模型,利用此模型与刀具实体模型做布尔减运算,实时模拟工件材料的去除加工过程,并验证加工结果.在此基础上,根据切削力、切屑形成原理,提取几何仿真中的切削层参数和一些相关参数,将其应用于切削力计算和切屑仿真中,形成几何仿真和物理仿真集成的数控车床仿真系统.
From the features of NC turning process, a workpiece decomposition expression model based on the constructed units was put forward, and Boolean subtraction was performed using this model and a tool solid model to simulate the real-time process of cutting and validate the simulation result. Based on the above and the principle of cutting force and chip generation, cutting parameters and some related parameters in geometric simulation, such as cutting depth and cutting velocity, were extracted and used in the calculation of cutting force and the simulation of chip. This NC turning machine simulation system is the integration of geometric and physical simulation.
