The Adhesion Damage Model to Predict the Adhesive State at the Tool/work Interface

Abstract

Adhesion always forms on the tool surface during cutting of carbon steel. The periodic evolution (formation, growth and fall-off) of adhesion has the significant effects on the cutting process, such as tool wear, finished surface roughness and so on. Because adhesion formed on the tool surface can keep the tool away from the workpiece and protect the tool from wear to some extent, so we can make use of it to realize the low-wear cutting. The aim of this study is to predict the periodic evolution of adhesion with less cutting experiment data. The model validation is performed by comparing simulation with experimental results. From the analyses, it is found that the adhesion damage model can predict the adhesive state at the tool workpiece interface with considerable accuracy. Furthermore, the relationships between the frequency of adhesion and tool wear, finished surface roughness were also discussed.
