Abstract

A method for machining and finishing a metallic member to provide a finished product without any additional process uses a lathe and a milling process. A non-circular metallic member on a worktable is rotated, and lathe tool moved backwards and forwards to machine the peripheral top portion of the metallic member. The path of the lathe tool machines curved surfaces of the top portion of the metallic member. The rotation of the metallic member is then stopped, and a milling cutter is brought to meet the peripheral sidewall of the metallic member. The movement and feeding of the milling cutter is predetermined. The worktable rotates the metallic member to enable one end edge of the peripheral sidewall and then another to face the milling cutter, and have the end edge chamfered by the milling cutter.

First claim

What is claimed is:

1. A milling method for machining metallic member using lathing and milling, comprising:
(1) providing a machine comprising a machine support, a worktable, a moving device, a lathe feeding mechanism, and a milling 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 lathe feeding mechanism and the milling feeding mechanism are slidably assembled to the moving device along a second direction perpendicular to the first direction, the lathe feeding mechanism comprises at least one feeding assembly and a lathe tool connected to the at least one feeding assembly, the at least one feeding assembly is configured for driving the lathe tool to move along a third direction substantially perpendicular to the first and second direction reciprocally, the milling feeding mechanism comprises a milling cutter and is configured for driving the milling cutter to move along the third direction, 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, thereby cooperates with the lathe tool;
(2) positioning a 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 comprising an end edge away from the top portion;
(3) applying the worktable to rotate with the metallic member;
(4) controlling the lathe tool to move backwards and forwards toward the metallic member to machine the top portion of the metallic member circumferentially;
(5) moving the lathe tool by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member;
(6) holding the metallic member to stop rotate, and moving the lathe tool away from the metallic member;
(7) driving the milling cutter to rotate and contact the peripheral sidewall of the metallic member;
(8) moving the milling cutter along a predetermined path, simultaneously controlling a feed of the milling cutter relative to the metallic member; and
(9) 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 by the milling cutter along a predetermined path, simultaneously controlling a feed of the milling cutter relative to the metallic member.

2. The method of claim 1 , wherein the peripheral sidewall comprises a plurality of side surfaces arranged in order and adjacent two of the plurality of side surfaces is connected by a corner, step (8) further comprises when the milling cutter finishes milling one side surface, the milling cutter 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 to adjust a position of the milling cutter relative to the metallic member, until the milling cutter arrives at an adjacent side surface to the side surface that has been milled, and followed by repeating the machining steps on the adjacent side surface.

3.
