摘    要:当前的积层制造技术主要采用2.5D切片。成形中台阶效应不可避免,本文提出了一种新的基于3D切片的适应性成形方法。通过增加成形工具的运动自由度,使之能根据实体的几何外形自动调整姿态,从而有效地克服了台阶效应对成形精度的影响。在保持同等成形精度的前提下。采用适应性斜切成形技术可以使用更厚的层片。提高成形效率,实现了成形精度和速度的兼得。

关 键 词:成形工具  姿态调整  适应性积层制造技术  快速原型制造  分层  CAD  CAM  直纹面  斜切成形  成形机

Abstract:Current laminated manufacturing techniques are mainly 2.5 dimension slices. So, the staircase effect in rapid prototyping processes is unnevitable. In this paper, an adaptive slicing method based on 3 dimension slices is discrible in detail. Through increasing the degree of freedom by tilting the laminated tool of RP machine, those slices achieved by line interpolation between adjacent contours can more closely match the designed surface shape than the zero order approximation. The results of sometest show that the new method may significantly reduce build time and improve the surface finish through the use of thicker sloping layers for the same userdefined error.
Keywords:Rapid prototyping technology  Slice  CAD/CAM  Ruled surface
