| 目的 对表面粗糙度和材料去除率作为输出参数的磨料水射流铣削45#钢过程进行研究，旨在寻找最优加工参数。方法 对射流去除材料机理进行了分析，设计并进行了以磨料粒度、射流压力、横向进给距离、靶距为加工工艺参数的田氏正交实验。采用Minitab对不同实验参数组合下磨料水射流加工45#钢的表面粗糙度、材料去除效率进行了数据分析，并从材料去除机理方面，对4种加工工艺参数对于铣削表面质量和材料去除效率的影响程度和影响趋势，以及各因素之间的交互作用进行了分析。结果 对射流铣削面表面粗糙度影响较显著的因素是横向进给距离，射流压力次之；对于材料去除效率，磨料粒径的影响最显著，横向进给距离次之。结论 综合材料去除效率和表面粗糙度值，选出最优加工参数：磨料粒径2000目，射流压力120~160 MPa，喷嘴横移距离1.0~1.5 mm，靶距约30 mm。 |

| The work aims to find optimal machining parameters by studying the process of milling 45# steel with abrasive water jet which takes surface roughness and material removal rate as output parameters. Material removal mechanism was analyzed, Tian orthogonal experiment with abrasive particle size, jet pressure, transverse feed velocity, target distance as machining process parameters was designed and performed. Minitab was used to analyze surface roughness and material removal efficiency of 45# steel subject to abrasive water jet machining in different experimental parameter combinations, impact and impact trend of the 4 machining process parameters on milled surface quality and material removal efficiency from the aspect of material removal mechanism, and interaction among different factors. Transverse feed distance had the most significant effect on jet milled surface roughness, jet pressure took the second place. Abrasive particle size had the most significant effect on material removal efficiency, transverse feed distance took the second place. The optimal machining parameters are selected as follows by allowing for material removal efficiency and surface roughness: abrasive particle size of 2000#, jet pressure of 120~160 MPa, nozzle sidesway distance of 1.0~1.5 mm and target distance of about 30 mm. |
