[0002] Turning blade of numerical control machine is the cutting tool used when turning in numerical control machine, mainly used for cutting workpiece. Turning blade is part of turning tool, usually including cutting edge and handle two parts. Cutting edge is the most important part of blade, can be processed according to certain geometric parameters, has cutting, cutting, shearing and other functions. Handle is the support and clamping part of blade, can fix blade on machine tool or tool, and transmit cutting force. Turning blade has wide application in metal processing, especially in turning, milling, cutting groove, thread turning and other fields. With the development of technology, the application of indexable turning blade is increasingly widespread, and becomes the mainstream product in modern metal cutting application field.
[0003] Although turning blade has high hardness and wear resistance, but under certain extreme machining conditions, blade is still prone to wear, and the existing turning blade tool bit needs to be replaced after wear. Since turning blade is usually made of high-quality materials such as hard alloy, ceramic and the like, the cost of these materials is high, and the frequent replacement of blade increases production cost. The existing turning blade cuts too long chips, which easily leads to machining error and reduces machining accuracy.
