Digit controlled machine tool real time error compensator for off centering machine tool exterior coordinate system

Abstract

The invention is a digital lathe error real-time compensator based on lathe external coordinate system offset. It includes calculating and processing module, CNC port and motion control module, sensor and transmitting module. The sensor and transmitting module is linked with calculating and processing module by data cables. The calculating and processing module is linked with CNC port and motion control module by data cables and communication protocol and acquires the input and output, saving, calculating of the signals. The CNC port and motion control module offsets the lathe external coordinate system to extra move the lathe by service system according to compensating value received as signals outputted from the calculating and processing module. The sensor and transmitting module gathers the temperature and heat error signals of the lathe and transmits to processing module after processed. The calculating and processing module may links with the computer so to acquire the command and data transferring and saving between the superior and inferior machine. The invention is of simple structure, handily use, low cost, highly real-time, more efficient compensation with a bright industrializing foreground.

Description

technical field [0001] The invention relates to a real-time error compensation device for a numerical control machine tool, in particular to a real-time error compensator for a numerical control machine tool based on the offset of the external coordinate system of the machine tool. The invention belongs to the technical field of precision machining machine tools. Background technique [0002] At present, the domestic market share of China's domestic CNC machine tools is only 30%, and there is still a downward trend. It is necessary to import a large number of CNC machine tools every year, which not only costs a lot of foreign exchange, but also is often controlled by others when importing advanced machine tools. Compared with machine tools manufactured in advanced countries, my country's machine tools have two main problems: one is low precision, and the other is poor reliability. Therefore, it is of great significance to improve the precision and reliability of machine to...

Problems solved by technology

It is necessary to import a large number of CNC machine tools every year, which not only costs a lot of foreign exchange, but also is often restricted by others when importing advanced machine tools.

Compared with machine tools manufactured in advanced countries, my country's machine tools have two main problems: one is low precision, and the other is poor reliability.

At present, the domestic numerical control system is not widely used in the domestic market, and the number of open numerical control systems has not been widely used. Therefore, the application and implementation of this kind of compensator is complicated, the application area is narrow, and it is not universal, so it is difficult to promote practical applications.
