A Feature-Enhanced Remote Machining Process Monitoring Method

Machining process monitoring is essential to guarantee machining quality and reduce production cost, especially for the parts with complex structures and high accuracy requirement. However, effective machining process monitoring is still a challenge in industry. Particularly, a smooth communication between remote control computers and CNC (Computerized Numerical Control) systems is required. To address this requirement, a remote machining process monitoring method based on features and web is proposed. Machining feature model is established to facilitate the communication among the involved modules in the system. A web-based method is adopted to realize remote monitoring and control for multiple machines, as well as to alleviate the computational load of CNC systems. In addition, a feature-based database is constructed as a communication hub, where feature information, monitoring strategies and monitoring results are stored. A prototype system has been developed to validate the feasibility of the proposed method.
