Research on cutting performance of Superrigid aluminum alloy turning with PCD tool Due to its advantages of high hardness, high strength, low density and excellent mechanical properties, superrigid aluminum alloy is widely used in aviation, aerospace, rail transit and automobile.In aviation and automobile manufacturing industries, the dimensional accuracy and surface roughness of structural parts are highly required, while in actual PCD tool cutting production of superrigid aluminum alloy, the selection of processing parameters mostly depends . There are many researches on the machining of superhard alloy with carbide tool or the machining of ordinary aluminum alloy with PCD tool, but there are few researches on the cutting performance of superhard alloy with PCD tool.Therefore, it is necessary to conduct experimental research on the turning of superhard aluminum alloy with PCD tool, and analyze the cutting performance such as cutting force and surface roughness of turning...
