浅谈数控机床的爬行现象

Crawling Phenomenon of CNC Machine Tools

数控机床在低速进给时，会发生非匀速爬行，对加工精度和工件表面质量非常不利。本文主要研究爬行现象的一种数学模型建立，分析发生爬行现象的临界速度，推导出影响临界速度的各个因素。

CNC machine tool feed at low speed occurs when the non-uniform crawling on the machining accuracy and surface quality is very negative.This paper studies the phenomenon of a mathematical model of crawl established,an analysis of the phenomenon of the critical speed crawling,derived the various factors affecting the critical speed.
