钻削中产生迷切现象的机理研究

Researches on the Mechanism of Raudom Walking Phenomenon in Drilling

随着科学技术的发展．对孔加工精度的要求越来越高．钻削过程中的速切现象对孔加工的形状精度、位置精度有很大的影响．本文用试验、观察、解析的方法分析了钻头迷切现象与各种因素的关系，对提高孔加工精度有了新的揭示．

With the development of the advanced scientific Technology, more and more accurate requirments of the precision work for holes are required. In drilling prooess, a phenomenon of random walking has a considerable effect on form and location accuracy. The authors have explained the relationship between the phenomenon and other factors by means of testing, abserving and analysing. These explanations provides some new ways for improving the precision work.
