Milling method for machining metallic member

A milling method for machining metallic member, comprising:

• (1) providing a machine comprising a machine support, a worktable, a moving device, and a miller feeding mechanism, wherein the worktable is positioned on the machine support;
• the moving device is slidably assembled to the machine support along a first direction and located above the worktable, the miller feeding mechanism is slidably assembled to the moving device along a second direction perpendicular to the first direction, the miller feeding mechanism comprises a milling cutter and is configured for driving the milling cutter to move along a third direction perpendicular to the first and the second directions, the worktable comprises a first rotating member and a second rotating member, the first rotating member is mounted on the machine support, the second rotating member is mounted on the first rotating member, the second rotating member is capable of rotating the metallic member along the third direction to match up the motion of the milling cutter, thereby cooperatively adjusting a position of the milling cutter relative to the metallic member, the worktable further comprises a third rotating member, and the first rotating member is mounted on the third rotating member;
• (2) positioning the metallic member on the worktable, the metallic member comprising a top portion and a peripheral sidewall extending from a peripheral edge of the top portion, the peripheral sidewall comprises an end edge away from the top portion, wherein the peripheral sidewall comprises a plurality of side surfaces arranged in order and a plurality of corners each connecting two adjacent side surfaces;
• (3) driving the milling cutter to rotate, and resist the peripheral sidewall of the metallic member;
• (4) applying the worktable to rotate the metallic member to enable the end edge of the peripheral sidewall to face the milling cutter, and chamfering the end edge along a predetermined path, simultaneously controlling a feed of the milling cutter relative to the metallic member wherein the first rotating member rotates the metallic member along the second direction upward to enable the end edge on one side surface to face the milling cutter, the miller feeding mechanism chamfers the end edge, when finishing chamfering the end edge on one side surface, the first rotating member rotates the metallic member along the second direction downward, then the milling cutter moves to an adjacent side surface to the side surface which the milled end edge located on, the third rotating member rotates the metallic member along the first direction to change position of the metallic member relative to the milling cutter, until the end edge on the adjacent surface face the milling cutter, such that the milling cutter chamfers the end edge;
• and
• (5) moving the milling cutter along a predetermined path to mill the peripheral sidewall, simultaneously controlling a feed of the milling cutter relative to the metallic member, wherein when the milling cutter finishes milling one side surface, it arrives at one corner of the peripheral sidewall, the moving device drives the milling tool mechanism to move along the first direction and the second direction, accompanying with the worktable drives the metallic member to rotate, thereby cooperatively adjusting a position of the milling cutter relative to the metallic member, then the milling cutter arrives at one adjacent side surface of the peripheral sidewall.
