Investigation into Influence of Feed Speed on Surface Roughness in Wire Sawing

Abstract

Aimed at obtaining the minimum machined surface roughness at an appropriate feed speed during the wire-sawing process, the theoretical mathematical model of material removal rate of the non-rigid cutting tool-wire saw is presented, which is based on the Preston equation. According to this theoretical model, this diamond wire-sawing experiment is designed to study the effects of feed speed on machined surface roughness. The experimental results indicate that the minimum machined surface roughness can be acquired by setting the process parameters as the setting curve of spindle speed and feed speed. The investigation provides the theoretical basis and research methods for study of this kind of wire-sawing machine and optimizing process parameters, in order to obtain a low-roughness machined surface.
