At the same time, in order to decrease the break and hollow occurred in machining process, a new method named machining tool-path interactive modification and optimization based on nurbs have been provided for the complicated surface panel and fast-response in machining process of the sheet metal incremental forming achieved 本文介紹了金屬板材數(shù)控漸進成形技術(shù)的過程、原理,同時,主要針對加工過程中發(fā)生的破裂、凹陷等缺陷,提出了一種基于nurbs的加工軌跡人機交互修改和優(yōu)化的方法,解決了復雜曲面零件無法加工的難題,實現(xiàn)了金屬板材數(shù)控漸進成形加工過程的快速響應。
