A method of manufacturing a tubular component including rough machining the exterior surface of a solid billet 1 to reduce the size thereof and form two flanges. An axial blind bore 6 is then machined in the billet 1, after which a probing operation is carried out on the interior surface of the bore 6 in order to check the concentricity. A straightening operation is then performed on the billet in order to reverse any curvature along the longitudinal axis. A further machining operation is then performed on the outside to reduce the wall thickness of the bore before measuring the wall thickness of the bore 6 around the circumference of the billet 1 at least at two different axial positions. The billet 1 is then checked again and a final machining operation is then performed in order to form any ports and upstands which are required.

A method for manufacturing an aircraft door with an integral structure. The method includes the following steps: producing a forged blank (7); die-cutting the forging blank (7) between a substantially smooth lower die (8) and an upper die (9) defining a plurality of cells and producing a die-cut part having a honeycomb structure having an open face and a closed face closed by a wall; an inner wall of the honeycomb structure is machined to define at least one recess defined by a web connecting the closed face and the open face and a base protruding substantially perpendicular to the web on the open face of the die cut component.

An exemplary process includes determining a desired pore size, selecting an initial pore size greater than the target pore size, manufacturing a porous structure with the initial pore size, forging the porous structure to form a forged part having the desired pore size, and forming an orthopedic device from the forged part.

A climbing system includes a treestand and a plurality of climbing sticks. The treestand includes a monolithic platform formed from strengthened material. Each of the climbing sticks includes a frame having a plurality of weight-reduction apertures formed therethrough. Tree engaging structures include ramped surfaces to facilitate smooth downward sliding on a tree. Methods of manufacturing a treestand and climbing sticks are also disclosed. The method of manufacturing a treestand includes providing a solid, strengthened piece of material and removing portions of the material to form openings between structural supports.

Tube forming methods can be used for efficient transition in the production of tubes having varying thickness. Material used to form consecutive tubes may have the same thickness along a separation plane separating a first discrete section from a second discrete section of the material, and the first discrete section and the second discrete section may each have varying thickness in a feed direction of the material. With such a thickness profile, the first discrete section of the material may be formed into a first cylinder having varying thickness and separated from the second discrete portion as the second discrete section is formed into a second cylinder having varying thickness. In particular, the transition between the first cylinder and the second cylinder may be achieved without scrap and/or interruption, resulting in cost-savings and improvements in production throughput associated with forming tubes having varying thickness.

Disclosed are a wheel lightweight machining fixture and method. The fixture comprises a rotating chuck, an electric cylinder, a guide rail, a slide block, a first linear motor, radial positioning blocks and the like. When the electric cylinder drives the slide block to move along the guide rail, the position where an first ultrasonic thickness measuring sensor is in contact with a wheel spoke can be adjusted, so that the spoke thicknesses at different positions can be detected. Through motion of the turrets, an second ultrasonic thickness measuring sensor can contact the outer rim of the wheel and detect the rim wall thickness. By integrating a measurement feedback system into the manufacturing process, the disclosure provides a fixture and a method for minimum entity machining of the rim wall thickness and the spoke thickness of a wheel during the first stage turning process, thereby realizing lightweight manufacturing of the wheel.
