Research on Wear Characteristics of CVD Composite Coated Tool in Natural Marble Cutting

Abstract:

The high speed milling test of CVD composite coated tool cutting natural marble is carried out. Measured milling forces of different parameters by the dynamometer and analyzed the influence of different parameters on the cutting force. Observed the wear appearance by the SEM and analyzed the wear mechanism of CVD tool. The results of the experiment show that the cutting force increases along with the cutting depth and feed speed increase, decreases along with the spindle speed and the influence of the cutting depth is the largest. The wear mechanisms of CVD tool when milling the natural marble include the removal of mechanical loss on the tool substrate, oxidation wear and adhesion wear. The removal of mechanical loss and adhesion wear couple with the whole process of CVD composite coated tool.
