摘要

It was carried out that a HSM test for aluminum alloy (2A70) rotor with carbide cutter. It was investigated and analyzed that the influence of different cutting speed and feed speed on the roughness of blade's finished surface. The experiment showed that high quality surface was easy to obtain by increasing the cutting speed and decreasing the feed. But when the cutting speed crossed the critical value, increase in the cutting speed caused slight decrease in the surface roughness. The feed decreased to a very small value, the roughness increased a little. It was expected that best surface roughness and machining efficiency could be obtained by selecting the appropriate cutting speed and feed.
