specific Embodiment

[0028] Taking the turning of titanium alloy with cemented carbide tool as an example, using cold plasma jet as cooling and lubricating medium can reduce tool wear and improve the quality of machined surface.

[0029] Tool 2 is titanium alloy Ti6Al4V bar stock, tool 3 is grade K05 (YG3X), cutting amount is: cutting speed 80m / min, cutting depth 0.5mm, feed speed 0.1mm / r.

[0030] The cold plasma jet generator 1 uses a bare electrode discharge form, and the cold plasma jet generated by such electrodes will not cause arc breakdown discharge between the metal and the metal. The two electrodes are a nozzle electrode made of brass and a needle electrode made of tungsten carbide, and the vertical distance between the two electrodes is 2.5mm.

[0031] The high-voltage power supply 7 adopts an intermediate frequency sine wave AC power supply, with an output frequency of 50k-120kHz, an output voltage of 0-10kV, and a maximum power of 150W; the high-voltage output end of the high-voltage ...

Abstract

The invention provides an atmospheric cold plasma jet auxiliary cutting method. Cold plasma jet generated under atmospheric pressure is used as a lubricating cooling medium during material cutting. Working gas enters a cold plasma jet generator from a working gas source via a pressure reducing valve and an adjustable flow meter, the flow of the working gas and output voltage of a high-voltage power source are adjusted so that uniform cold plasma jet is sprayed out from a nozzle outlet of the cold plasma jet generator, the temperature of the jet is the room temperature or is slightly higher than the room temperature, and a tool and workpiece interface and a tool and chip interface are always soak in the cold plasma jet during cutting by means of adjusting a spraying angle. Plasma can be generated in a dielectric barrier discharge mode, a suspension electrode discharge mode or a bare electrode discharge mode. The atmospheric cold plasma jet auxiliary cutting method is an environment-friendly cutting method, an excellent lubricating and cooling effects for various metal and nonmetal materials can be realized during cutting, accordingly, cutting force is reduced, the service life of a tool is prolonged, and the quality of the surface of a workpiece is enhanced.

Description

technical field [0001] The invention relates to a method for lubricating and cooling cutting processing, which belongs to the technical field of cutting technology of mechanical manufacturing. Background technique [0002] During cutting, especially when cutting difficult-to-machine materials, a large amount of cutting heat will be generated, which will increase the cutting temperature, increase the cutting force, intensify the tool wear, and affect the surface quality and dimensional accuracy of the workpiece to be processed. The common methods of cooling and lubrication in the cutting area mainly include: pouring cutting fluid, minimal quantity lubrication (MQL) technology, water vapor cooling method, low temperature cold air cooling method and liquid nitrogen cooling method. The pouring cutting fluid method can enter the cutting area to really lubricate and cool the cutting fluid in a very small amount. After the cutting fluid is heated in the cutting area, it will quickl...
