Embodiment Construction

[0096] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0097] see Figure 1 to Figure 3 As shown, in the case of adopting the double-photographing point mode, the method for real-time control of the machining tool path of the CNC machine tool based on machine vision includes the following steps:

[0098] (1) The CNC machine tool system reads and parses the instruction photo information of the processing file; the processing file is a single photo point processing file, which includes the following parts:

[0099] (a) The photographing point part of the initial processing instruction, the photographing point part of the initial processing instruction includes several photographing groups, and each photographing group includes two instruction photographing points and a position calculation notification command message;

[0100] (b) The photographing point part of the follow-up processing instructi...

Abstract

The invention relates to a real-time path control method for a processing tool of a numerical control machine based on machine vision. The method comprises the following steps: reading and analyzing instruction photographing information of a processing document; scanning and correcting a position mark of a photographing point; reading and analyzing inspection information of the tool routine of the processing document; carrying out real-time control inspection of the tool routine; reading and analyzing the information of the tool routine of the processing document; and carrying out motion control on the tool of the machine. By adopting the real-time path control method for the processing tool of the numerical control machine, a part in accordance with current actual condition in a higher accuracy range can be processed so as to realize real-time correction to the tool routine, a corresponding processing mode can be selected, the number of a routine unit can be defined and the processing status can be set flexibly so as to improve the processing efficiency on the premise that the processing accuracy is ensured, and simplify steps of operation control. The method has stable and reliable working performance and wider application range, and establishes solid foundation for further development of the tool routine control technology of the numerical control machine.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to the technical field of control of machining tools of numerical control machine tools, and specifically refers to a method for real-time control of machining tool paths of numerical control machine tools based on machine vision. Background technique [0002] Manufacturing is the basic industry of the national economy, and the level of manufacturing is an important indicator of a country's industrial development. The quality level of CNC machine tools is related to the level of the national manufacturing industry. [0003] In the process of machining with CNC machine tools, there is a type of parts, such as mobile phone panels, whose contours have been silk-screened on the workpiece board, so the cutting tool must be strictly followed the contours of the silk-screened board to process the required parts. However, due to the installation error of the workpiece and the...
