摘要
在分析深孔钴削时影响孔的中心线偏移因素的基础上,根据弹性力学原理并利用有限元法,推导了深孔钻削时孔中心线偏移量的计算公式,并提出了减小孔中心线偏移量的措施.
After analysing the causes of centre-line offset in drilling depth-hole in details, on the basis of the principle of the elasticity mechanics and the finite element, the formulas calculating the centre-line offset in drilling depth-hole are deduced and the good method-reducing centre-line offset are presented.
