The Digital Manufacturing Equipment and Development of High Speed and High Precision with Monitoring and Intelligent Maintenance

With the development of science technology in aerospace, automobile and ship, energy and military, the product parts space type face increasingly complex and surface quality requirements more stringent. So there are higher requirements to the digital manufacturing equipment to realize high speed and high precision machining. This paper summary the related research in condition monitoring, remote control, fault diagnosis and intelligent maintenance, and based on the lack of monitoring and diagnosis technology of whole life cycle, unperfected quality control technique, the lower intelligent level in the current equipment, it establish full range monitoring and the whole life cycle of the intelligent maintenance system and present fault diagnosis, control and maintenance solutions for the whole life cycle, and point out the new development direction of the integrated monitoring and intelligent maintenance in CNC equipment.
