Abstract:An automatic control system of on-line micro hole drilling monitoring based on virtual instruments is developed to avoid the drill breaking during the process of micro hole drilling. The system can accomplish the signal collection, the data treatment and storage of the electrical currents of the spindle motor accompanying with the warning and the withdrawal of the drill once the overload of the electrical currents of the spindle motor. It has many advantages, such as simple structure, high monitoring precision, strong anti-jamming ability, and so on. The test results have shown that on-line micro hole drilling monitoring with the above system can avoid effectively the drill breaking and improve the utilization ratio of the drill.
Keywords:Virtual Instrument  Micro Hole Drilling  Real-time Monitoring  Control System
