CNC (Computer Numerical Control) machining plays a crucial role in the manufacturing of aerospace components: precision parts, but it also faces a series of difficulties. The following are some of the main difficulties summarized based on the provided search results:
CNC machining aerospace parts usually require the use of special materials, such as titanium alloys, superalloys, nickel alloys, etc. These materials have high strength and hardness, but they are also difficult to process. For example, titanium alloys have low plasticity but high hardness, and they tend to bond with cutting tools, increasing the processing difficulty.
CNC precision machining parts of aerospace components requires multiple steps, including cutting, grinding, assembly, etc. In each step, it is necessary to control the machining accuracy and reduce costs as much as possible on the premise of ensuring quality. Especially in the machining of precision parts, to complete high-precision machining tasks, precision part machining processes such as machining centers and wire cutting need to be adopted. These processes all require controlling the machining error within a very small range, so the machining difficulty is greater.
Although CNC machining technology can improve production efficiency and part quality, the initial investment is relatively high, including equipment purchase, software development, and personnel training. For some small and medium-sized enterprises, this may cause certain economic pressure. Therefore, when introducing CNC machining technology, enterprises need to conduct a detailed cost analysis to ensure the rationality of the investment.
The rapid replacement of technologies also requires CNC machining to constantly adapt to new requirements. With the advancement of aerospace technology, new materials and processing techniques are emerging continuously, and CNC machining also needs to be upgraded and improved accordingly. To better promote the development of CNC machining in the aerospace field, relevant enterprises and research institutions can strengthen cooperation and carry out technological research, development and innovation.
The quality of precision CNC machining parts is directly related to flight safety. Therefore, strict quality control is required during the production process. In CNC machining, the computer control system can monitor various parameters in the machining process in real - time, such as temperature and cutting force, to ensure that the machining is always in the optimal state. In addition, in the later inspection, high - precision measuring equipment can be used to evaluate the dimensions and shapes of the parts to ensure that they meet the design requirements.
Difficult-to-machine materials such as aluminum alloys and titanium alloys for aerospace applications have advantages such as high strength and light weight. However, their machinability is poor, which easily leads to problems such as tool wear and high machining difficulty. How to overcome the challenges brought by the material characteristics and improve the efficiency and quality of CNC metal machining is an urgent problem to be solved at present.
