Research on Fault Knowledge Base Technology of High-End CNC Machining System

Abstract:

In the high-end CNC machining process, the stability and reliability of the running state of the machining system directly affects the machining accuracy and work-piece quality. In order to effectively ensure the reliable, stable, safe operation of the high-end CNC machining system, the fault knowledge base technology construction for the cutting tool system is carried out. It focuses on the high-end CNC machine tools, and build the condition monitoring system test platform with cutting tool system as the core; the fault sample acquisition method based on the rough set theory is proposed; a knowledge base model construction technology is conducted; and the network-based sample acquisition test platform is established, so as to provide users with data information on the operation of cutting tool system, and provide the key test techniques for the generation mechanism of the dynamic performance and wear condition of the operation of cutting tool system and for the analysis of the intrinsic correlation between the characteristic parameters and wear condition of cutting tools.
