Embodiment Construction

[0021] Below in conjunction with the embodiment shown in the accompanying drawings, the present invention is described in detail as follows:

[0022] The tool switching method is detected based on the tool load waveform mode, which includes the following steps:

[0023] A. Use the existing tool load data acquisition system to collect the load data of the CNC machine tool during work without interruption;

[0024] B. Classify and mark the waveform difference corresponding to the load of typical tool cutting and tool changing;

[0025] C. Screen out the effective data during cutting and tool change, and establish the tool change model by the tool diagnosis system for the tool load during cutting, and separate the effective tool cutting load data;

[0026] D. According to the created tool change model and tool information, for the tool load collected after the tool change model is created, through the in-depth data analysis of the mathematical model in the diagnosis system, the ...

Abstract

The invention relates to a tool load waveform mode based tool switching detection method. The method comprises the following steps that A, load data of a numerical control machine tool during work are continuously collected in the whole process by utilizing an existing tool load data collection system; B, waveform differences corresponding to loads during typical tool cutting and tool changing are classified and marked; C, effective data during cutting and tool changing are screened out, a tool changing and cutting model is established through a tool diagnosis system according to the tool loads during cutting, and effective tool cutting load data are separated out; and D, according to the established tool changing and cutting model and tool using information, the tool loads collected after the tool changing and cutting model is established are subjected to depth data analysis through a mathematical model in the diagnosis system, a suitable tool is calculated according to waveform feature matching of tool changing and cutting, the data synchronization problem of different signal sources can be solved, and the tool state can be distinguished more accurately.

Description

technical field [0001] The invention relates to a tool switching method based on tool load waveform mode detection. Background technique [0002] In recent years, with the expansion of production scale, improvement of processing quality, and the need to reduce manufacturing costs, precise management of tool life is an important means of response, and its status monitoring has become an important topic at present. Restricted by the processing capability, detection means and data memory of the current CNC system, there is no complete data collection and data analysis capability in the cutting state of the tool. It is analogous to the judging means of on-site experience personnel. There are methods such as vibration during tool cutting, audio analysis, load change, etc., which are different from the management of the numerical control system. External auxiliary means are used to judge the tool from data collection and external calculation. state. Since the external data sampl...
