曲面铣削中刀具路径的自适应研究

Studying on the adaptive strategies for cutter-feeding in machining surface

如何高效率、高精度的完成自由曲面的数控加工 ,是机械制造领域的研究工作者一直追求的目标。针对这一问题 ,提出了全曲面等误差和均匀粗糙度加工的概念。建立了能实现这种加工的刀具路径自适应模型及其算法。分析表明 :该模型所确定的刀具路径 ,在相同精度下可达到最高加工效率。

Machining surface with high efficiency and high precision is the aim which the scholars of the field have been aspired for all belong on this question.In the paper,a new conception about equal errors and uniform roughness on whole surface is proposed.Then,a model about adaptive strategies for cuter-feeding and it's algorithm which can achieve the machining are established.Analysis shows that the method can achieve the highest machining efficiency under given precision.
