Cutting device, method and tool processing method based on micro-textured tool. The invention realizes the low-speed reciprocating swing around the arc center of the blade by means of the arc knife, and controls the current knife contact area to periodically reciprocate and migrate along the arc-shaped blade, so that the blade participates in cutting point by point. Such a beneficial effect is that the cutting edge can be cooled point by point. Further, when the micro-textured tool is used, with the reciprocating swing of the tool, the cutting fluid stored in the micro-textured structure is strongly squeezed into the cutting area, soaking into the rake face and chips. In the contact area, the lubrication state of the chip surface transitions from boundary lubrication to fluid lubrication, and the friction coefficient can be greatly reduced. In addition, the combination of time-varying tool contact area and micro-textured tool, when the tool contact area turns away from the material being cut At this time, the tool contact area is fully cooled immediately, and the cutting fluid inside the micro-woven structure can also be replenished in time, without stopping the machining process, the cooling and lubrication effect of the tool is improved and the cost is minimized, reducing the grinding force and current grinding Point temperature, while greatly increasing the amount of tool wear, prolonging the service life.
