Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

A method for machining a longitudinal profile section having an actual length and a first and a second end, wherein the first and the second end are machined using respectively a first and a second tool head and material is continuously abraded by the first and second rotating tool head during a machining period, the machining period is divided into time increments (ti), a torque (M(ti,) M(ti)) of the tool head is measured for each time increment (ti) and an individual energy consumption (E(ti), E(ti)) is determined for each time increment (ti), said individual energy consumption corresponding to an individual quantity of material abraded during the time increment (ti), and a total energy consumption (E(t), E(t)) both of the first and of the second tool head is determined from the individual energy consumptions (E(ti), E(ti)), said total energy consumption corresponding to the total quantity of abraded material.

A tool for machining chamfers includes a tool body defining a first reference and a second reference configured for proper positioning of the tool body on a workpiece. A router port is defined through the tool body to provide access to the workpiece for a router. A router attachment proximate the router port is configured to position a router mounted to the router attachment for machining a chamfer in the workpiece with reference to the first and second references.

A three-dimensional shaping method including the steps, after a lamination step, in which steps of forming a powder layer, flattening with a squeegee and sintering are repeated, followed by cutting of the surface of the laminate, 1. setting the overall shape of an object to be shaped by a CAD/CAM system, and setting machining units that form the overall shape and cutting allowances on peripheral sides and upper sides of each of the machining units, 2. cutting of the peripheral sides and upper sides according to a prescribed order, after lamination with addition of a cutting allowance on the peripheral sides of each machining unit, and after carrying out lamination to the thickness of the cutting allowance on the upper side of the machining unit and the machining unit adjacent above the machining unit, and 3. continuing repetition of step 2, from the lowest to the topmost machining unit.

A chamfering device includes: a main body including, at a proximal end side thereof, a shank to be attached to a main shaft of a machine tool, the main body including, at a distal end side thereof, a shaft portion extending in a rotational axis direction; a movable body whose proximal end portion is mounted to the shaft portion, the movable body being configured to rotate together with the shaft portion and be movable in the rotational axis direction; an urging member configured to urge the movable body in a direction toward the distal end of the main body; a chamfering tool mounted to a distal end portion of the movable body and configured to rotate together with the movable body to perform chamfering on an edge portion of a workpiece; and a following member mounted to the movable body such that a position of the following member relative to the movable body in the rotational axis direction is invariable and the following member is rotatable relative to the movable body, the following member being configured such that a distal end thereof comes into contact with a surface of the workpiece.

A chamfer tool includes a main body, a driving shaft and a plurality of milling members. The main body, which rotates along an axis, has an inner surface and an outer surface located on opposite sides thereof; wherein the main body further has a plurality of mounting portions, each of which is connected to the inner surface and outer surface. The driving shaft is fixed to the main body to drive the main body to rotate. Each of the milling members has a first blade and a second blade, wherein the milling members are mounted on the mounting portions of the main body with the first blades protruding from the outer surface of the main body and the second blades protruding from the inner surface of the main body.

A cutting tool includes a tool body having a peripherally disposed outer insert receiving pocket and an interiorly disposed inner insert receiving pocket with a cutting insert resiliently clamped therein. The tool body includes a through recess at least partially circumferentially bounded by a recess circumferential surface. A resilient clamping member extends into the through recess. The inner insert receiving pocket is formed by the resilient clamping member and a recess pocket portion of the recess circumferential surface. A chamfering cutting insert may be retained by the resilient clamping member, without the use of an additional, separate clamping device.
