The Experimental Research on High-Speed Machining Surface Quality of Aluminum Alloy Holes

In high-speed machining,cutting velocity and thrust velocity are crucial factors to affect the machining surface roughness. This paper first theoretically analyzes the changing rule of surface roughness for different cutting parameters when aluminum alloy holes are being cut at high speed by PCD lathe tools. Then it validates the optimum parameter values by doing a lot of experiments. The experiments verify that proper parameters can improve the machining quality of the products.
