Predictive Modeling and Impact Analysis of Cutting Force in Boring Titanium Alloy Based on SVR Modeling
Titanium alloy is an important material in aerospace manufacturing,which is characterized by light weight,high strength and corrosion resistance,but it is also difficult to be machined.For the cutting force of titanium alloy boring,the test analyzes the influence of three process parameters,namely,boring speed,feed and depth of cut,on the cutting force.Firstly,eight groups of titanium alloy boring tests with different parameter combinations were carried out to actually measure the cutting force during machining,and then the Support Vector Regression(SVR)model was used to determine the prediction model of the cutting force,and finally the influence law of each process parameter on the cutting force was analyzed.The test results show that the cutting force is most affected by the depth of cut,followed by the boring speed,and the feed has the least influence.
