【摘要】：三维工艺全信息工序模型贯穿整个三维工艺设计、制造过程。在三维工艺全信息工序模型的构建中,能否对中间工序模型进行快速建模直接影响了三维工艺全信息工序模型构建的效率。为了提高已有三维工艺设计系统的适用性,便于对其进行推广应用,提供了一种基于刀轨的工序模型生成方案,通过计算刀具沿刀轨运动所成包络面来切削毛坯零件,实现仿真切削,形成本步工序模型,并对通过在此工序模型上添加零件几何信息、工艺信息来构建三维工艺全信息工序模型的方法进行了探讨。通过实例验证了该理论方法的可行性。
[Abstract]:Three-dimensional process information process model runs through the whole three-dimensional process design and manufacturing process. In the construction of 3D process full information process model, whether the intermediate process model can be quickly modeled has a direct impact on the efficiency of 3D process full information process model construction. In order to improve the applicability of the existing 3D process planning system and facilitate its popularization and application, a process model generation scheme based on the tool track is provided, which can be used to cut the blank parts by calculating the envelope surface formed by the tool moving along the tool track. The simulation cutting is realized and the process model of this step is formed. The method of constructing the 3D process model with geometric information and process information is discussed. The feasibility of the method is verified by an example.
