Abstract

Abstract:

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.

Key words: institutional analysis, hybrid machine tool, position inverse solution, workspace, parameter decoupling, Monte Carlo method, spatial influence parameters, motion constraints
