Abstract

The invention discloses a numerical control machine tool edge data acquisition and thermal error compensation system based on the Internet of Things. Thenumerical control machine tool edge data acquisition and thermal error compensation system comprises an edge computing unit, a temperature acquisition unit, a wireless data transmission unit, a local server and a cloud server, wherein the edge computing unit is respectively connected with the temperature acquisition unit, the numerical control machine tool and the wireless data transmission unit, the local server is respectively connected withthe cloud server and the wireless data transmission unit, and the temperature acquisition unit comprises at least one temperature acquisition card. By adopting the Internet of Things technology, dataacquisition, thermal error compensation and remote data interaction of the machine tool can be realized.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tool data acquisition and thermal error compensation, and in particular relates to a numerical control machine tool edge data acquisition and thermal error compensation system based on the Internet of Things. Background technique [0002] With the gradual improvement of the speed, acceleration and machining accuracy of CNC machine tools, geometric errors and thermal errors have become important factors restricting the improvement of the accuracy of CNC machine tools. In the case of continuous progress in related technologies such as CNC machine tools and parts design, manufacturing, assembly, and materials, static errors such as geometric errors have been gradually improved, and the proportion of comprehensive errors in CNC machine tools is gradually decreasing. A large number of research and processing practices have shown that under high-speed and high-precision processing cond...
