Real-time monitoring and self-adaptive control system and method for tail end running state of numerical control milling machine

Abstract

The invention discloses a real-time monitoring and self-adaptive control system and method for the tail end running state of a numerical control milling machine. The system comprises a vibration sensor, a data collector, a data analysis processor, a data storage server and numerical control equipment. The vibration sensor is installed at the tail end of a spindle or an angle milling head of the numerical control milling machine and used for monitoring vibration signals of the tail end running state of the milling machine in real time, and the data analysis processor conducts spectral transformation analysis processing on collected vibration data, recognizes abnormal information or vibration in the cutting process of the milling machine, stores the processed data in the data storage server,generates a corresponding control instruction according to the identified abnormal information, and sending the control instruction to the numerical control equipment so as to implement adaptive control. The system can identify the abnormal running state of the equipment, early warn potential risks existing in the cutting process of the tail end of the milling machine and immediately send the control instruction, so that the running safety of the equipment is effectively improved, and the enterprise cost is reduced.

Description

technical field [0001] The invention belongs to the field of parts mechanical processing technology equipment, and is especially suitable for the real-time detection and self-adaptive control system and control method of the terminal running state of shell parts when they are processed by a numerical control milling machine.
