MIlling application in aerospace industry

In the last few decades, the aerospace industry has seen a good example of the replacement of existing materials and still in progress. A large part of the modern aircraft is made up of innovative lightweight materials such as carbon fiber reinforced plastics (CFRP) and aluminum alloys. Recently, the auto industry is also trying to replace the auto body parts from CFRP to steel to compensate for the weight gain caused by batteries in hybrid electric or all electric power systems. Therefore, it is also due to the increased use of CFRP in the wind energy, sports and molding composites industry. It is estimated that the demand for fiber reinforced plastics (FRP) will increase in the next few years.

 
Because in most cases, the quality of parts is not enough after forming FRP once, so in order to meet the requirements of high dimension and surface quality, especially in the aerospace industry, it is usually necessary to process the inside and outside contour lines. The superior performance of CFRP puts forward high requirements for milling and drilling processes, because they are composed of fiber and two phase composite structures with different properties of matrix materials, which are accompanied by uneven and anisotropic configurations. High strength brittle carbon fibers are embedded in the temperature sensitive synthetic matrix, and the high loss effect leads to the main wear in the process.
