Abstract

The contact angle affects the life and accuracy of a linear guideway. A novel method for measurement the contact angel of linear guideway is proposed by using the photoelastic effect and digital image processing techniques. Tests of the method on a sliced linear guideway with various loadings demonstrate its usefulness. The stress distribution of the guideway is further studied by using the finite element method and the photoelastic experiment. The results can be useful for structural design of the linear guideway.
