在大倾角曲面或悬空特征等复杂形状熔积零件的制造中,应用等厚度切片技术来进行制造往往达不到成形性要求和实际使用性能.为解决这种问题,提出不等厚切片技术来改善制造效果.基本思想是沿着零件几何渐变生长方向的法平面进行等距切片,切片法向始终保持与零件几何特征的渐变方向一致.这种切片方法考虑了零件的几何形状的变化,始终保持最优的生长方向,因而制造出的零件无论在外部形貌还是内部力学性能上都可以得到最优效果.将该方法应用在复杂渐变结构零件的精确数字化熔积制造中,取得了满意的实验结果.
In the manufacture of complex shaped fused parts such as large dip surfaces or floating features, the application of equal thickness slice technology often can not meet the formability requirements and practical performance.In order to solve this problem, Improve the manufacturing effect.The basic idea is to make isometric slices along the normal plane of the geometric gradient growth direction of the part, and the slicing normal direction is always consistent with the gradual direction of the geometric features of the part.This slice method takes into account the change of the geometry of the part, And maintain the optimal growth direction, the manufactured part can get the best effect both in external shape and internal mechanical properties.This method is applied to the accurate digitized deposition manufacturing of complex and gradual structural parts, and the satisfactory Experimental results.
