Abstract: To reduce the vibration of molybdenum wires in high-speed WEDM cutting tool and improve machining accuracy, the vibration of molybdenum wires is modeled based on the string theory. The major influence factors of the vibration are worked out and they are the velocity, tensile force and length of the molybdenum wires. Orthogonal test method is employed to test the vibration under the multiple factors. The experimental results proved the accuracy of the model and method. This research will be helpful for reducing the vibration.
