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;
• (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;
• (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;
• 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.
