[0002] With the rapid development of modern manufacturing, precision manufacturing and intelligent manufacturing have become the mainstream trends in the industry. Against this backdrop, the performance requirements for machining equipment are constantly increasing, especially in terms of precision, efficiency, and intelligence. Traditional vertical machining centers, while playing an important role in the machining field, are increasingly revealing their inherent limitations.

[0003] Traditional vertical machining centers often lack real-time dynamic monitoring capabilities during the machining process. This means that operators cannot immediately understand the machine tool's operating status, tool wear, workpiece machining accuracy, or any abnormal changes during machining. This lack of information can not only lead to a decline in machining quality but also cause machine tool malfunctions and even safety accidents.

[0004] Therefore, developing an intelligent vertical machining center with machining status monitoring capabilities has become an important direction in the research and development of current machining equipment. This intelligent vertical machining center, by integrating advanced sensor technology and intelligent algorithms, can monitor the machine tool's operating status and various abnormal changes during the machining process in real time. Simultaneously, it can transmit this monitoring data to the control system in real time, achieving closed-loop control of the machining process, thereby greatly improving machining quality and efficiency.

[0005] In conclusion, developing intelligent vertical machining centers with processing dynamic monitoring functions will not only help improve the precision and efficiency of machining equipment, but also promote the development of the manufacturing industry towards intelligence and precision.

[0044] Working principle

[0045] As attached Figure 1-15As shown, when machining the workpiece, the workpiece 17 is first clamped, and the milling cutter 11 is adjusted to a suitable position by the lead screw I6. The servo motor 8 is started to machine the workpiece 17. During this process, the machining platform 13 and the saddle 12 drive the machining table 14 to slide horizontally along the X and Y directions according to the machining requirements. When the machining center is machining the workpiece 17, the spindle monitoring component, the spindle monitoring component, the workpiece monitoring component, and the machining table monitoring component are started simultaneously for monitoring.

Accelerometer 34 can monitor the acceleration of machining table 14 in three directions to obtain the mechanical performance of machining table 14 during machining. At the same time, the spindle monitoring component, workpiece monitoring component, and machining table monitoring component are electrically connected to PLC 18. PLC 18 processes the monitored signals and transmits signals to PC bus industrial computer 19. PC bus industrial computer 19 calculates and analyzes the monitored signals to obtain the overall monitoring results of machining center mechanical characteristics, dynamic accuracy, motion parameters, and temperature. It then analyzes and feeds back the motion status of each component of the machining center, thereby enabling real-time monitoring of the machining center's operating status, the wear of milling cutter 11, the machining accuracy of workpiece 17, and various abnormal changes during the machining process. This achieves comprehensive real-time monitoring of the machining process, improving machining accuracy and efficiency.
