Dual cutting milling tools for removing material from a workpiece include two cutting portions, with one cutting portion being configured for ruled milling, and the other cutting portion being configured for hemstitch milling. In this manner, the number of tool changes for a given manufacturing process may be reduced. Dual cutting milling tools include a first cutting portion and a second cutting portion both formed in a shank, with the first cutting portion being configured to perform hemstitch milling on the workpiece, and the second cutting portion being configured to perform ruled milling on the workpiece. Methods of removing material from a workpiece may include both hemstitch milling the workpiece with the first cutting portion of the dual cutting milling tool and performing ruled milling of the workpiece with the second cutting portion of the dual cutting milling tool, without changing tools in the milling machine.

A milling device for machining a slot into an inner surface of a casing for a gas turbine engine. The milling device includes a frame assembly including multiple structural guides configured to engage structural features on the inner surface of the casing to maintain an axial position of the milling device relative to a longitudinal axis of the casing. The milling device also includes a milling cutter coupled to the frame assembly. The milling device is configured to be displaced in a circumferential direction relative to the longitudinal axis to machine the slot, via the milling cutter, along the inner surface of the casing in the circumferential direction.

The machining method uses a tool to machine a workpiece set in a jig, the workpiece has a plate-like web part arc-shaped in plan view and a flange part bent and arranged vertically from an edge along the arc shape, the tool has an end cutting edge and a peripheral cutting edge, and the jig has a surface where the web part is placed and a contacting surface where the flange part comes into surface contact. The machining method includes: pressing the flange part against the contacting surface; cutting the flange part by the peripheral cutting edge by feeding the tool in an arc direction of the arc shape; and cutting the web part by the end cutting edge by feeding the tool in the arc direction.

An aeronautical aluminum alloy minimum-quantity-lubrication milling machining device includes a machine tool worktable and spindle connected with a machine tool power system. The spindle is connected with a tool holder that is fixed with a cutting tool. The machine tool worktable is provided with a machine tool fixture, the tool holder is connected with a minimum-quantity-lubrication mechanism, the machine tool fixture includes a fixture body that is fixedly provided with a limit block for contact with two adjacent side surfaces of a workpiece, the fixture body is provided with a plurality of clamping elements capable of pressing the workpiece against an upper surface of the fixture body, and a top of the clamping element is provided with a detection member for detecting a relative position between the clamping element and the spindle. The device can avoid interference and contact between a nozzle and the clamping element.

A damper includes a damper body that is configured to be attached to a workpiece during a machining process. A first side of the damper body is configured to abut a first side of the workpiece. The damper body includes a frame forming an outer periphery of the damper body, a plurality of damper nodes with a cavity in each damper node positioned in the frame, and a plurality of ribs extending between the frame and the damper nodes. A damping material is positioned in the cavity of each damper node.

Every junction part for an airplane wing is manufactured with overmaterial. Each part is measured with a laser based interferometer or other scanning technique and the as built measurements are compared with a model to generate a new trajectory milling program to fill or prevent gaps between parts using a points cloud and B-Spline algorithm to generate a new surface to be milled. Once the program is generated (new trajectories) and post processed, it is sent to a milling machine to perform overmaterial milling on already milled parts with overmaterial. This technique can be used to eliminate gaps between junction parts and the corresponding need for shims.

A tool for machining a stacked material workpiece includes a tool body having one or more helical flutes extending to a forward end of the tool body. Each helical flute has a width defined by a first cutting edge and a second edge, a surface of the flute adjacent the first cutting edge facing the forward end of the tool body and a surface of the flute adjacent the second edge facing away from the forward end of the tool body. Each helical flute can include a first portion having a first negative pitch angle and a second portion having a second negative pitch angle different from the first negative pitch angle, the first portion extending from the forward end of the tool body to the second portion. The tool has only negative pitch angles. A method for machining a stacked material is also disclosed.
