数控卧式铣床滑枕变形有限元分析及补偿技术

Finite element analysis and deformation compensation technology of NC horizontal milling machine

针对机床滑枕自重弯曲变形问题,经有限元分析后,采用油压缸-拉杆补偿系统的方法,保证了在机床全行程内的精度,经实践证明,是一种精度高、经济而有效的方法。

Presents the method adopted pressure cylinder-draw rod compensation system and finite element analysis to solve the problem of back tilting of the square ram when is goes out to move forward on NC milling machine. The experiments show that this method can reach the accuracy requirement, and is effective and economical.
