Problems solved by technology

[0002] In the existing CNC machining process, the cutting route and cutting conditions of the tool are controlled by the instructions of the machining program. Usually, whether the machining process is abnormal is judged by empirical data. The cutting conditions change in real time during the actual cutting process, and the existing technology cannot achieve intelligent response.

Embodiment 1

[0053] An operation method of an intelligent control and monitoring system for processing, such as figure 1 As shown, it is achieved through the following steps:

[0054] Set the system to the learning mode, perform tool processing normally, and collect the power value at each instant;

[0055] Switch the system to the operating mode, and obtain the current state data of the device through various sensors;

[0056] Through the state predictor, predict the next state of the equipment, and compare the predicted state with the actual collected state;

[0057] According to the comparison results, it can automatically adjust various data in the state prediction period, and continuously and automatically adjust the feed rate and power of the equipment to protect the tools and improve the processing efficiency.

[0058] In some embodiments of the present invention, the intelligent control and monitoring system includes a machine tool axis drive module, a power sensor module, an adaptive contro...

Abstract

The invention provides an operation method of an intelligent control and monitoring system for a machining process. A standard sequence value formed by each instant power obtained in the learning process serves as reference power, when a machine tool machines a workpiece, a power collector obtains each instant power value of the machine tool, and the instant power value and the reference power value serve as input of an adaptive control system, a state observer predicts a power value in the next step, a deviation tending to be stable of a next instant system is calculated by means of a self-adaptive law and reference power of the next step, and finally a gain value of automatic intervention needed by the machine tool is obtained by a control law. Thus, the power of the machine tool is automatically controlled, a cutter is protected, and the machining efficiency is improved.

Description

Technical field [0001] The invention relates to the field of modern processing, in particular to an operating method of an intelligent control and monitoring system for processing. Background technique [0002] In the existing CNC machining process, the cutting path and cutting conditions of the tool are controlled by machining program instructions. Usually, whether the machining process is abnormal is judged by empirical data. In the actual cutting process, the cutting conditions change in real time, and the existing technology cannot achieve intelligent response. Real-time monitoring of the cutting process and status is well known in the art. There is an automatic monitoring method described in US Patent No. 4,208,718, which makes a judgment by recording the percentage of the target load duration relative to the total processing time. Summary of the invention [0003] The purpose of the present invention is to provide an operating method of an intelligent control and monitoring...
