基于磨料水射流的螺杆转子加工新方法研究

螺杆转子传统加工过程中存在刀具磨损和过高切削热量等难题。为此，将具有无刀具磨损、切削热量低、绿色环保特点的磨料水射流加工方法引入螺杆转子加工研究之中，提出了磨料水射流多轴联动加工螺杆转子的新方法，以提高转子加工精度和效率。采用任意拉格朗日与欧拉方法构建了转子加工模拟模型，将模拟分析结果与实验数据进行比较，验证了模拟模型的正确性。最后，通过磨料对水射流多轴联动加工模拟结果的分析，证明了螺杆转子加工新方法的合理性。

Research on a New Method for Screw Rotor Processing Using Abrasive Water Jet

In the traditional machining processes of screw rotors, there were problems such as tool wear and high cutting heat. Abrasive water jet machining had some characteristics of no tool wear, low cutting heat and environmental protection. An abrasive water jet was introduced into the research of screw rotor processing, and a new method of abrasive water jet was proposed to improve the machining accuracy and efficiency of the rotors. The arbitrary Lagrangian-Eulerian method was applied to construct the rotor machining simulation model, the accuracy of simulation model was verified by comparing the simulation results with the experimental data. Finally, through the analyses of the simulation results of multi axis machining of abrasive water jet, it is proved that the new machining method of screw rotors has certain rationality.
