The Precision Magnetic Abrasive Finishing Process And Experimental Research On The Surface Of Titanium Alloy Wire

Titanium alloy is an important structural metal with high specific strength,excellent corrosion resistance and weldability.It is widely used in shipbuilding heavy industry,aerospace,petrochemical and other fields.Titanium alloy wire is often widely used in arc fuse deposition technology,medical care,aerospace and other fields.In the manufacturing process of titanium alloy wire,the surface quality of titanium alloy wire is often poor due to insufficient lubrication and mold wear defects.Therefore,it is particularly important to adopt a more advanced grinding method to improve the surface quality of titanium alloy wire.Magnetic abrasive finishing technology as a kind of special processing technology is used in material surface finishing,capable of grinding magnetic abrasive in the magnetic field within the aggregated into has certain rigidity of magnetic abrasive brush,using the magnetic abrasive brush by copying and parcel to all-round grinding of titanium alloy wire,thus improve the finishing on the surface of the processed material.On the basis of referring to the relevant research results at home and abroad,this experiment uses magnetic particle finishing method to carry out magnetic abrasive finishing test on titanium alloy wire,and the main factors that affect the processing quality and processing efficiency are explored in detail.Through simulation and experimental analysis,the influence mechanism of technological parameters on surface quality of titanium alloy wire in finishing process by magnetic abrasive finishing method was analyzed.In the process of finishing titanium alloy wire with magnetic abrasive finishing method,the main process parameters,such as magnetic pole speed,abrasive particle size and feed speed,were analyzed and optimized.BP neural network genetic algorithm was used to establish the prediction model of magnetic abrasive finishing process parameters and surface quality according to the experimental processing parameters and surface quality,and then the optimal surface quality and process parameters were obtained,and the accuracy of the prediction results was verified by experiments.It is found that different shape of the head has different grinding effect on the polishing of titanium alloy wire by magnetic abrasive finishing.When the aggregation head Angle is 37°,the simulation analysis and experimental verification can be concluded that the aggregation head has a better processing effect compared to other shapes.The experimental results show that the convex edges on the surface of titanium alloy wire after magnetic abrasive finishing are basically removed,presenting a smooth and compact effect.After the use of multiple sets of experimental data and processing,the surface quality of the training of BP neural network by genetic algorithm neural network to achieve the optimum parameters to search,and predict the best surface quality,through the test of the reliability of the process parameters,got close to the predicted values of surface quality,you can come to the conclusion that The training results of BP neural network have a certain accuracy,and this method can be used in the actual production process of magnetic abrasive finishing and polishing of titanium alloy wire.
