摘　　要：针对传统三自由度串联雕刻机床难以加工空间复杂曲面的问题,文中给出了一种空间新型五自由度串并联雕刻机床的设计方案。在SolidWorks中建立该雕刻机床的三维模型,采用空间几何法建立了位置反解和参数解耦的数学模型,并在MATLAB中利用蒙特卡洛法生成了工作空间。通过对其工作空间分析可知,该雕刻机床的工作空间较大,在一定程度上可以满足对零件空间复杂曲面的加工需求。在此基础上,通过对该雕刻机床工作空间的分析发现,增大该新型雕刻机床工作空间较合适的方法是增加串联滑轨长度。In view of the problem that the traditional three-degree-of-freedom series-parallel engraving machine tool is difficult to process the complex surface in space,this study presents a novel type of five-degree-of-freedom series-parallel engraving machine tool in space.The three-dimensional model of the engraving machine is established in SolidWorks,the mathematical model of position inverse solution and parameter decoupling is established,and the workspace is generated by Monte Carlo method in MATLAB.The analysis of working space shows that the working space of the engraving machine tool is large,which can meet the processing requirements of complex surfaces in the part space to a certain extent.On this basis,through the analysis of the working space of the engraving machine tool,it is found that the suitable method to increase the working space of the new engraving machine tool is to increase the length of the series slide rail.
