With the rapid increase of the personalized customization demand and the continuous improvement of the production takt time requirement of the market, the performance optimization of the numerical control five-sided drill has become a key technical support for improving the competitiveness of manufacturing enterprises. The current mainstream numerical control five-sided drill control scheme exposes obvious adaptability deficiency problem in practical application. The traditional control system often adopts fixed parameter configuration, and is difficult to dynamically adjust according to different workpiece materials, thicknesses and processing requirements, so that precision fluctuation occurs in the processing process. Meanwhile, the existing scheme lacks an effective synchronization mechanism in the aspect of multi-axis coordination control, the motion coordination among all drill bit units is poor, and the overall processing quality is affected. More importantly, most solutions ignore the ability to monitor and feed back in real time during processing, and fail to respond to process state changes in time. Deep analysis finds that the key technical bottleneck for restricting the improvement of the performance of the numerical control five-sided drill is mainly concentrated on the key factor of insufficient self-adaptive capacity of a control algorithm. Because of the lack of an intelligent parameter optimization mechanism, the system cannot automatically adjust a control strategy according to actual machining conditions, so that the drilling precision is unstable under different working conditions. The lack of self-adaptive capacity further causes the problem of coordination of multi-axis motion control, and when each drill bit unit cannot obtain optimal motion parameters, the synchronization and coordination between the drill bit units are inevitably affected, so that the technical problems of low processing efficiency and uneven surface quality are caused. How to construct a set of intelligent control system with self-adaptive parameter optimization capability, realize dynamic response to different processing working conditions, and ensure high-precision synchronous movement of each drill bit unit through an optimized multi-axis coordination control strategy, thereby obviously improving the overall processing efficiency on the premise of ensuring the processing precision, and becoming a key problem of urgent breakthrough in the development of the current numerical control five-sided drilling technology.
