熔融沉积制造(FDM)是一种用填充方式来得到每层截面的快速成形工艺。因为填充路径的好坏直接影响着制件的质量和加工效率,所以选择一种合适的路径填充算法就显得非常重要。在众多路径生成算法中,复合式扫描法由于在制件精度和加工效率上的诸多优势,成为近期的研究热点。针对凹多边形凸分解得到的子区,应用一种偏置与直线复合式算法,对多边形轮廓进行填充。复合式路径填充算法作为FDM快速成形路径生成软件的核心算法之一,已成功应用在实际加工中。
Fused Deposition Manufacturing (FDM) is a rapid prototyping process that uses filling to get the cross-section of each layer. Because the filling path directly affects the quality of the workpiece and processing efficiency, so choose a suitable path filling algorithm is very important. Among many path generation algorithms, composite scanning has become a hot research topic in recent years because of its many advantages in terms of workpiece accuracy and processing efficiency. Aiming at the sub-region obtained by the concave polygon convex decomposition, a polygonal contour is filled by a combination of offset and straight line algorithms. As one of the core algorithms of FDM rapid prototyping path generation software, compound path-filling algorithm has been successfully applied in the actual machining.
