摘要
对熔丝沉积快速成形技术的轮廓偏置填充算法和并行栅格扫描填充算法进行了研究,并在此基础上提出了基于轮廓偏置和并行栅格的混合路径填充算法。同时,在该算法中嵌入了起点终点内置方法,将起点与终点置于制件的内部,提高了制件表面质量。最后,在实现算法的同时增加了G代码转换模块,将该算法生成的路径直接转换成标准G代码,使FDM的数控部分与数据处理部分独立开来,为FDM控制系统的改进提供了方便的数据接口。
The contour offset path and the parallel raster path of the fused deposition three-dimensional printing device were studied,and a hybridized path algorithm was proposed based on them.Meanwhile,the hybridized path was filled with the end node ensconcing optimization algorithm,which put the starting and ending nodes inside the products and improved the surface quality of products.Finally,G code conversion module was added after the realization of the algorithm,which converted the paths directly into the standard G code,so NC part of the FDM was separated from the data processing module,which provides a convenient data interface for the improvement of the FDM control system.
