introduction：（three）Milling method and its reasonable selection 1.Selection of milling methods The milling mode refers to the kinematical relationship between the milling cutter and the workpiece during milling。 (1)Perimeter milling（Circular milling method） There are two ways to mill a workpiece by circumferential milling，That is, up-milling and up-milling。When milling, if the cutting speed direction of the milling cutter rotating into the workpiece is opposite to the feed direction of the workpiece, it is called inverse milling，On the contrary, it is called down-milling。 ①Backmilling figure8-8aAs indicated，The cutting thickness gradually increases from zero
