开环CNC系统数据采样插补的关键技术研究

Study on key technique of time-slicing interpolating in open-loop CNC

在开环数控系统中采用数据采样法插补 ,可以有效提高系统性能。但要求其中的精插补脉冲必须均匀的分配到插补周期中。

Though time-slicing interpolation used in Open-loop CNC can prompt system performance effectively. Pulse of fine Interpolation must be Distributed Uniformly in an interpolation cycle. In this paper, an algorithm of fine interpolation, which can generate uniform pulse series, is proposed.
