Experimental Study on Cryogenic Cutting of High-strength Steel with Liquid Nitrogen Cooling

摘要：

As a modern manufacturing technology, cryogenic cutting technology is one of effective ways to improve machining efficiency of hard-cutting materials. With typical hard-cutting materials 35CrMnSiA and 45CrNiMoV high-strength steel as the research object, the comparison experiment between cryogenic cutting and dry cutting of two kinds of high-strength steels was made in this paper. In the changing cutting speed conditions, the cutting force and the surface roughness of two kinds of cutting were measured in this experiment.By changing the length of cutting stroke, the cutter wear of two kinds of cutting was measured, and a comparison of chip-breaking effects was made in the experiment.The experimental results indicate that the cutting force, surface roughness, and tool wear in cutting 35CrMnSiA and 45CrNiMoV high-strength steel under cryogenic condition are reduced, and chip-breaking effect of cryogenic cutting is improved. This may be attributed mainly to improve the machinability of higth-strength steel.
