How Milling Machines Work. Milling machines can be used on wood, metal, and nearly any other solid object to cut a range of shapes and sizes. They are most often automated by computer numeric control to carve out designs created in a computer-aided design program, but manually operated machines are also still common.Milling machines can be used in both horizontal and vertical orientations, and ...

The models are built with the establishment of locus function according to orthogonal turn-milling principle. Then based on these models, the influence law of surface topography affected by various cutting parameters is found by some simulation methods. The law also matches with orthogonal turn-milling surface roughness and topography experiments.
