Problems solved by technology
The severe plastic deformation of metal materials, especially titanium alloys, during the cutting process will generate a large amount of cutting heat that is concentrated in the cutting area and is difficult to discharge, resulting in defects such as resin softening, coating, and even burns in CFRP materials.

Abstract
The invention provides a milling and grinding tool and a manufacturing method thereof. The milling and grinding tool comprises a cutter base, a cutter handle arranged at one end of the cutter base, arectangular positioning head arranged at the end, far away from the cutter base, of the cutter handle, brass solder diamond abrasive particles, low temperature minimal-quantity lubricant cooling holes, chip spaces and an internal cooling minimal-quantity lubricant channel arranged inside the cutter base, wherein the brass solder diamond abrasive particles, the low temperature minimal-quantity lubricant cooling holes and the chip spaces are arranged on the surface of the cutter base in a single-layer ordered manner. Defects of resin softening, coating, burning, layering, tearing, surface scratching and the like which are extremely easily caused in the machining process of a stacked composite material at present can be avoided.
Description
technical field [0001] The invention relates to a milling tool for ultrasonic-assisted vibration processing of laminated composite materials and a manufacturing method thereof. Background technique [0002] As one of the earliest and most widely used composite materials in composite materials, carbon fiber reinforced resin composites (carbon fiber reinforced plastics, CFRP) are currently being gradually promoted and applied in the fields of national defense and aerospace. , Large specific modulus, excellent properties such as fatigue resistance and corrosion resistance. However, the CFRP material itself has the characteristics of low shear strength, high defect sensitivity, and low temperature resistance. Therefore, CFRP materials are often used with lightweight aerospace materials Al or Ti by screwing or riveting to obtain better comprehensive performance. [0003] As a typical anisotropic and non-uniform material, CFRP is prone to defects such as delamination, surface tea...
