Abstract: Vertical rigidity of the space self-adaptive φ530 high rigidity
mill is calculated by applying the boundary element method (BEM) of three-dimension elastic contact problem, which can
update the existed deforming separation calculating theory and
corresponding methods of material mechanics, elastic mechanics
and finite element method. The method has less hypotheses and
stronger synthesis in contact-type calculating model. The
advantages of the method are high calculating rate, high
calculating accuracy, etc..
Key words: Mill
rigidity Boundary element method Deforming separation Contact-type
