The research on cemented carbide tool wear

Titanium alloys have high strength to weight ratio, corrosion resistance, retention of strength at elevated temperatures and low thermal conductivity. In cutting of the titanium alloy, these characteristics have bad influence on tool wear. Therefore, the titanium alloy is generally machined in the milling at low cutting speed. Recently, the demand of the titanium industrial products is increasing and the high speed milling of the titanium alloy is desired. In this study, the Ti-6Al-4V alloy was machined at high cutting speed, and the tool wear progress and the cutting mechanics were experimentally investigated in order to clarify an effective tool material and cooling method for the cutting of the titanium alloy. The results obtained are as follows: In the cutting with a cemented carbide tool and coated cemented carbide tools of TiAlN, TiCN, DLC at the cutting speed 200 m/min, the wear progress of the coated tools were slower than that of the cemented carbide tool. The titanium alloy was cut in the dry and mist methods in order to avoid the thermal effect of the inserts, the wear progress in mist cutting was longer than that in dry cutting.

Coated Carbide

The machining efficiency of titanium alloy Ti6Al4V is low and the tool wear is serious. In this paper, uncoated carbide tool and two kinds of coated cemented carbide tool were used for dry turning titanium alloy. The experiments used CCD Observing System and the EDAX analysis of SEM to study tool wear mechanism and analyze the cutting performance through tool life, cutting force and cutting temperature. The results show that the main wear reasons are adhesion, diffusion and oxidation wear. For coated tool, the coating peeled off first, and then tool substrate damaged. Compared with coated carbide tool, the uncoated carbide tool with fine grain has longer tool life and lower cutting force and cutting temperature. The changes of cutting force and cutting temperature with cutting speed are not obvious when using the ccomposite coating (TiAlN and AlCrN) carbide tool. The results can help to choose tool material reasonably and control tool wear.

Ground Surface Roughness

Nano cemented carbide is a new style cutter material. Because its grain size is very small, it is superior to common cemented carbide in properties, such as high hardness, fracture toughness, flexural strength and higher abrasion resistance. As a cutter material, nano cemented carbide has wide use. In this paper, nano cemented carbide tool was ground with ELID technology, and the cutting properties of nano cemented carbide were studied, and the difference in cutting properties among the ultra-fine grain, common cemented carbide and nano cemented carbide was analyzed under the same condition. Results imply that the ground surface roughness of nano cemented carbide is obviously lower than that of common cemented carbide, and the tool life of nano cemented carbide is 5-7 times longer than that of common cemented carbide at low cutting speed.
