Abstract

The invention relates to a network group control-type error dynamic compensation system of numerically-controlled machine tools. The network group control-type error dynamic compensation system includes a machine tool error measuring instrument, a temperature sensor, a temperature data acquisition card, a first router, an industrial personal computer and a second router; a group control error compensation and monitoring subsystem is embedded in the industrial personal computer and includes an error modeling module, a state monitoring module and an error compensation module; and a secondary interface subsystems is embedded in each numerically-controlled machine tool and includes a communication module, a machine tool parameter access module and an error compensation implementing module. Compared with the prior art, and according to the network group control-type error dynamic compensation system of the invention, each module is matched with each other, such that error dynamic compensation and state information monitoring of a plurality of numerically-controlled machine tools can be realized on one industrial personal computer, and therefore, the machining accuracy of the numerically-controlled machine tools can be improved in a batched manner. The network group control-type error dynamic compensation system has the advantages of high compensation efficiency, high compensation precision and low implementation cost.

Description

technical field [0001] The invention relates to a numerical control machine tool error compensation technology, in particular to a network group control type error dynamic compensation system of a numerical control machine tool. Background technique [0002] With the rapid development of aerospace, precision instruments and other fields, people's requirements for the accuracy of CNC machine tools are increasing, and precision and ultra-precision machining technology has gradually become the research focus of modern manufacturing technology. Since the error compensation technology was put forward, it has been widely concerned because it can improve the accuracy of machine tools economically and effectively. In addition, Siemens 840D CNC system is a fully digital and highly open CNC system developed by Siemens. It has a highly modular and standardized structure, represents the development direction of today's CNC system, and occupies a high market share in high-end machine too...
