Abstract
Titanium alloy wire is characterized by high specific strength, good corrosion resistance, high-temperature resistance and other excellent comprehensive performance. It has been widely used not only in aerospace, shipbuilding and other high-tech fields, but also increasingly in medical equipment, food safety and other fields. Because titanium alloy wire is relatively difficult to process, it has a large deformation resistance, good elasticity, high flexion ratio and more serious rebound. During the processing, adhesion problems may occur, thus reducing the surface quality. The magnetic abrasive finishing (MAF) has good flexible machining characteristics. In this study, the rotating magnetic field was loaded on the titanium alloy wire, and the magnetic abrasive was absorbed by the magnetic field force to form a magnetic abrasive brush, so as to realize the precision processing of the titanium alloy wire. Under the same processing time, when the angle of the magnetic head was 37°, the surface roughness of titanium alloy wire was reduced to 0.28 μm by MAF, which improved the processing quality and efficiency of the titanium alloy wire.
Highlights
Titanium alloy wire is widely used in medical and health, the military industry and other fields because of its advantages, such as small density, high specific strength and good corrosion resistance.due to the limitation of current titanium alloy wire manufacturing, surface defects such as bulges and edges are produced during the reproduction process [1–5]
It is the main method to solve the problem in the magnetic abrasive finishing of titanium alloy wire, which optimizes the surface quality and improves the machining efficiency
We explored the influence of different shapes of the magnetic head on the surface quality and processing efficiency of titanium alloy wire
Summary
Titanium alloy wire is widely used in medical and health, the military industry and other fields because of its advantages, such as small density, high specific strength and good corrosion resistance. Magnetic particle brush continuously cut and scratched the surface ofof the titanium alloy wire wrapped inside, thereby acting on the titanium alloy wire. When the titanium alloy wire is is being processed, the sum force ofof the magnetic abrasive inin the magnetic field which synthesizedbybytwo twoforces. It is the main method to solve the problem in the magnetic abrasive finishing of titanium alloy wire, which optimizes the surface quality and improves the machining efficiency. In this experiment, we used Maxwell software (16.0, ANSYS, Inc., Canonsburg, PA, USA) to simulate the distribution of magnetic field intensity in the processing area of different shapes of the magnetic head [24]. We explored the influence of different shapes of the magnetic head on the surface quality and processing efficiency of titanium alloy wire
