The Investigation of Tool Wear in High Speed Cutting INCONEL718

Abstract:

As the main method of high efficiency machining Ni-based superalloy, high-speed cutting can not but intensify the cutting-tool wear. So, it is very necessary to find the rule of cutting-tool wear in high-speed cutting superalloy, especially, the effect of cutting-tool wear on the cutting force, cutting temperature and surface roughness of machined workpiece. In this paper, the PCDTiAlN cemented carbide insert is used in the experiment, the value of cutting-tool wear and the corresponding cutting force, cutting temperature and surface roughness of machined workpiece is measured. It indicates that the cutting force, cutting temperature and surface roughness of machined workpiece is changed corresponding the cutting-tool wear changes, and cutting-tool is serious, for example, the crater wear expands quickly; the boundary wear is obvious.
