Influence of Three Cutting Elements on Tool Marks on Workpiece Machining Surface
摘要
The influence of various cutting parameters on the surface morphology of high-strength aluminum alloy 7075-T6 was studied by dry cutting with YBG102 nano coated alloy tool. It is found that the influence on the surface roughness of the workpiece is the greatest，followed by the cutting depth and the cutting speed；On the premise of ensuring cutting efficiency，the faster the cutting speed，the smaller the cutting depth，the faster the cutting speed，the smaller the cutting depth，and the better the machining effect. It is difficult to adjust the geometric shape of 3D surface with three elements，but the maximum value of the surface is more affected by the tool feed speed and depth.
