基于零件留量模型的半精加工方法研究与仿真

摘要

留量模型可以如实反映毛坯适时的残留状态，基于留量模型的加工方法可以改善加工轨迹，保护刀具，提高加工效率。在论述留量模型原理和建立过程的基础上，研究了基于留量模型的半精加工方法所具有的特点与优势，然后利用UG软件中的工序模型（ IPW）模块对这种加工过程进行了描述和分析，并给出了具体的仿真实例，研究结果表明这种加工方法可以为零件的数控加工带来很大的便利。%Stock-remaining model can accurately reflect the residual condition of the rough, processing methods that were based on the stock-remaining model can optimize tool path, protect tools, and improve the processing efficiency.On the basis of the principle and building process about the stock-remaining model, the characteristics and advantage of semi-finished methods based on the stock-remaining model are researched in this paper, then description and analysis on the working process are conducted by using the IPW module of UG software, then the machining simulation examples are provided.The re-sults show that it is convenient and useful to the NC machining.
