Abstract

A method for machining a metallic member to provide a finished appearance uses a lathe and a milling process. A metallic member comprising a top portion and a peripheral sidewall is provided, the metallic member is positioned on the worktable. The worktable is rotated with the metallic member, the lathe tool moved backwards and forwards to machine the top portion of the rotary metallic member circumferentially. The lathe tool is moved by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member. After rotation, the milling cutter is rotated, and resists the peripheral sidewall of the metallic member. The milling cutter is moved along a predetermined path, and the milling cutter is fed the metallic member to achieve the required shape and finish.

First claim

What is claimed is:

1. A 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 comprising a first rotating member, a rotating shaft, and a second rotating member, the first rotating member is mounted on the machine support through the rotating shaft, the second rotating member is positioned on a middle portion of the rotating shaft, the second rotating member is configured to rotate the metallic member along the third direction to cooperative with the lathe tool and the milling cutter;
(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, 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;
(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 to resist 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, 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 feeding mechanism to move along the first direction and the second direction to adjust a position of the milling cutter relative to the metallic member, and the second rotating member rotates the metallic member along the third direction until one adjacent side surface of the peripheral sidewall is rotated adjacent to the milling cutter.

2. The method of claim 1 , further comprising, while adjusting the position of the milling cutter relative to the metallic member, continuing machining the corner by the milling cutter until the milling cutter arrives at the adjacent side surface, and followed by repeating the machining steps on the adjacent side surface.

3. 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 feeding mechanism to move along the first direction and the second direction, simultaneously rotating the metallic member with the worktable, thereby cooperatively adjusting a position of the milling cutter relative to the metallic member, then the milling cutter arrives at an adjacent side surface to the side surface that has been milled.

4. The method of claim 3 , wherein in the process of adjusting the position of the milling cutter relative to the metallic member, the milling cutter machines the corner till the milling cutter arrives at the adjacent side surface, and followed by repeating the machining steps on the adjacent side surface.

5. The method of claim 1 , wherein in the step ( 4 ), the moving device first drives the lathe feeding mechanism to slide along the first direction and the second direction until the lathe tool arrives at an original position above the worktable; then the at least one feeding assembly drives the lathe tool to move backwards and forwards along the third direction according to a depth of cutting required for each machining portion of the top portion.

6. The method of claim 5 , wherein the lathe feeding mechanism further comprises a sliding saddle and mounted seat fittingly assembled to the sliding saddle, the sliding saddle is slidably connected to the moving device along the second direction, the at least one feeding assembly is received in the mounting seat, and the milling cutter is slidably mounted on the mounting seat.

7. The method of claim 5 , wherein the lathe feeding mechanism further comprises a sliding saddle and a mounted seat, the sliding saddle is slidably connected to the moving device along the second direction, the mounting seat is slidably mounted on the sliding saddle along a fourth direction substantially parallel to the third direction, the at least one feeding assembly is received in the mounting seat, and the milling cutter is slidably mounted on the mounting seat; step ( 4 ) further comprises, after the lathe tool arrives at the original position above the worktable, the mounting seat is controlled to drive the lathe tool to move along the fourth direction to reach a preset position near the metallic member, then the at least one feeding assembly drives the lathe tool to move backwards and forwards.

8. The method of claim 7 , wherein the milling feeding mechanism comprises a linear driving assembly mounted on the moving device, the linear driving assembly drives the milling cutter to move along the third direction to adjust the feed of the milling cutter relative to the metallic member.

9. The method of claim 8 , wherein the milling feeding mechanism further comprises a linking board, and a rotatable driving member configured for rotating the milling cutter, the linear driving assembly is mounted on the sliding saddle and located adjacent to the mounting seat, the linking board is slidably assembled to the sliding saddle and driven by the linear driving assembly, the milling cutter is mounted on an end of the rotatable driving member.

10. The method of claim 9 , wherein the lathe feeding mechanism further comprises a tool holder slidably connects with the mounting seat, the tool holder comprises a main body and a sliding board protruding substantially perpendicularly from the main body, the main body is positioned out of the mounting seat, the sliding board is received in the mounted seat, the main body comprises two separated holding portions positioned on a surface thereof facing the sliding board, the mounting seat comprises two sliding portions protruding from an outer surface thereof, each of the two holding portions slidably engages with each of the two sliding portions of the mounting seat, the lathe tool is fixed on the tool holder.
