Background
The laminated material composed of the carbon fiber reinforced composite material (CFRP) and the titanium alloy integrates the excellent characteristics of light weight, high strength and the like of the carbon fiber reinforced composite material (CFRP) and the titanium alloy, and is widely applied to the aviation manufacturing industry. The airplane assembly is an important link in the airplane manufacturing process, the overall safety performance and the service life of the airplane are obviously affected, and the machining of the airplane assembly mounting hole is directly related to the airplane assembly precision. For the carbon fiber reinforced composite material (CFRP)/titanium alloy laminated material, the carbon fiber reinforced composite material (CFRP) is easy to generate the defects of layering and tearing, the titanium alloy has high strength and low thermal conductivity, and the hole making quality of the carbon fiber reinforced composite material (CFRP)/titanium alloy laminated material is difficult to ensure due to the difference of the material properties of the titanium alloy and the CFRP, so that the popularization and the application of the carbon fiber reinforced composite material (CFRP)/titanium alloy laminated material in the aviation manufacturing industry are limited.
In order to meet the precision requirement of drilling a hole in a carbon fiber reinforced Composite (CFRP)/titanium alloy laminated material, drilling, expanding and multiple reaming are required for machining one hole in the traditional process, so that the drilling efficiency is low, the automation degree is low, the labor intensity is high, and a large number of machining tools are required for drilling, expanding and multiple reaming, so that the economic benefit is poor. Helical hole milling is a new technology which is developed in recent years for the hole machining of typical difficult-to-machine materials such as titanium alloys and carbon fiber reinforced Composites (CFRP). The method has the advantages of small cutting force, high hole making quality and high processing efficiency, and becomes a key technology for integrally making holes in carbon fiber reinforced Composite (CFRP)/titanium alloy laminated materials.
The development of spiral hole milling equipment promotes the development and application of spiral hole milling technology. Compared with the traditional machine tool machining, the presently disclosed spiral milling device improves the spiral milling environment and enables the operation to be more convenient and faster. However, the existing device can not effectively solve the problems of difficult matching of the process parameters of the carbon fiber reinforced Composite (CFRP)/titanium alloy laminated material, high requirement on processing quality, depth of a processed hole and the like. Therefore, a more intelligent and innovative processing technology or device is needed to realize the integrated hole-making processing of carbon fiber reinforced Composite (CFRP)/titanium alloy laminated material with high precision, high efficiency and high quality.
