AI Technical Summary

Problems solved by technology

The structure of the adaptive control system is complicated, and the setting of control parameters is cumbersome. Due to the use of the torque sensor, the application technical requirements and cost of the device are relatively high, and the invention only involves a simple turning process, not a far more complicated turning process. milling process

Embodiment Construction

[0017] The system structure of the present invention is as figure 1 shown. The whole system includes four parts: a plurality of monitoring devices 3 , a hub 2 and a management server 1 , and a plurality of monitoring devices 3 are connected to the management server 1 through the hub 2 .

[0018] The monitoring device 3 is installed on the CNC machine tool 4, collects data such as current and vibration in real time, predicts and judges in real time whether the cutting force exceeds the safe range, whether the cutter tooth is damaged or collides and other crisis situations occur, and takes corresponding measures to ensure that the machine tool, cutting tool, etc. and workpiece safety. At the same time, the device can also communicate with the CNC machine tool 4, receive status information from the CNC machine tool 4 itself, and transmit the information, collected data and processing results of the device to the management server 1 in time. The management server 1 processes and...

Abstract

The invention provides a numerical control machine tool processing performance monitoring system which is characterized in that monitoring devices on a plurality of machine tools are connected with each other by Ethernet network by a management server; the monitoring device receives the data of the self-state of the machine tool, collects the current of a mainshaft motor and a feeding motor and the vibration quantity of a mainshaft, processes the collected data, compares the processing result with the judgment standard of the machine tool processing performance, emits control instructions to control the processing process according to the given control strategy, and feeds back all relevant information to the management server; the management server analyses the processing performance state and the development trend of the machine tool. The system carries out monitoring to the self-parameters and the in-situ processing state of a plurality of the machine tools, analyses the current processing performance the development trend of the machine tool, and self-adaptively controls the complex processing process, thus effectively ensuring the processing safety and quality.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a processing performance monitoring system of a numerically controlled machine tool. Background technique [0002] Machine tools are the foundation of industry, and any industrial manufacturing production is inseparable from machine tools. The precision and development level of machine tools determine the industrial level of a country, so it is very important to improve the precision and level of machine tools. An important aspect that reflects the level of the machine tool is whether the machine tool itself can control the processing process and monitor the processing performance of the machine tool itself, and process the monitored information in a timely manner, and take effective measures to ensure the safety, reliability and quality of processing. NC machining is realized based on the information prepared in advance, and its essence is an open-loop processing method, whic...
