Abstract
For 45steel, the noise test of different groove milling inserts in milling processing is carried on and the distribution model is studied. Firstly, the cutting noise test system is designed and the acquisition scheme of the test points is determined; secondly, the noise tests in the dry milling process are carried on and the test results are analyzed. Also the influence degree of different milling parameters on the noise of milling inserts is analyzed and the distribution situation of the noise size with different milling parameters is compared; finally, using stepwise regression analysis method, the milling noise distribution models of different groove inserts are set up. Research shows that: in the same machining conditions, different groove inserts, which with complex grooves and a periodic function grooves have the best machining performance. All above study results will provide a certain theoretic base for improving the workshop environment, controlling and predicting the noise and optimizing the design of insert groove.
