Study on force distribution and its location in granite sawing

Abstract

The present work proposed a model of the location of resultant force based on tangential force distribution. Afterwards, the actual location of resultant force was calculated based on the analysis of the force components in the sawing contact zone. Based on the experimental results, it is found that the distribution coefficient and the location of the resultant force are both great influenced by depth of cut and workpiece feed speed except sawblade speed. The value of the distribution coefficient ranges from 1.375 to 0.416, and the location of the resultant force ranges from 0.727 to 0.568, which both decrease with the increase of depth of cut and workpiece feed speed. Furthermore, a good corresponding relationship between the location of resultant force and the distribution coefficient was obtained, which not only validates the force location model but also further reveals the characteristics of force distribution and its location in the contact zone.
