曲面铣削中刀具路径的自适应研究

摘要

Machining surface with high efficiency and high prec ision is the aim which the scholars of the field have been aspired for all belon g 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 fo r cuter-feeding and it's algorithm which can achieve the machining are establish e d.Analysis shows that the method can achieve the highest machining efficiency un der given precision.%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。
