Open CNC Machine Tool's State Data Acquisition and Application Based on OPC Specification

Abstract

For open CNC machine tool, user can develop third-party software based on OPC specification. Besides, CNC machine tool produce massive state data in machining process, which real time reflect the states of the machine. In this paper, the structure of open numerical control system is introduced, then data acquisition and compression based on OPC specification is implemented, finally data mining of the status data and its application in the intelligent fault warning and diagnostic is proposed. This research is critical to realize the digit and smart factory.
