Abstract:In order to explore the matching performance between YG tool and 7050 aluminum alloy.In this pa ̄
perꎬ7050 aluminum alloy was selected as the research object. Two kinds of cutting tools for cutting test were YG3 and
YG6.The test results show that the value of cutting force and surface roughness of YG3 tools is higher than that of YG6
toolsꎻ The cutting surface topography of YG6 tool is better than YG3 tool.It shows that performance matching of YG6
is better between tool and 7050 aluminum alloy than that of YG3.
