A method for manufacturing probes includes forming a recessed portion on a plate such that the plate has a first subsidiary plate, a second subsidiary plate and a third subsidiary plate mutually connected. The first subsidiary plate has a first thickness. The second subsidiary plate corresponds to the recessed portion and has a second thickness. The first thickness is larger than the second thickness. The second subsidiary plate is located between the first subsidiary plate and the third subsidiary plate. The third subsidiary plate has a third thickness. The third thickness is larger than the second thickness. Subsequently, the plate is held and cut by laser to form a plurality of probes. Each of the probes includes a probe tail formed from the first subsidiary plate, a probe body formed from the second subsidiary plate and a probe tip formed form the third subsidiary plate.

A method for manufacturing a titanium aluminide blade of a turbine engine, including production of a titanium aluminide ingot, extrusion of the ingot through an opening in a die having one main arm and at least one side arm, such as to obtain a extruded ingot having the shape of a bar with a cross-section having one main arm and at least one side arm substantially perpendicular to the main arm, transverse cutting of the extruded ingot such as to obtain sections of extruded ingot, forging of each section of extruded ingot such as to obtain a turbine engine blade.

An efficient method for producing spring strut forks for motor vehicles is presented. In each case two spring strut forks are produced from a metallic extruded profile as a starting product. The extruded profile has a central, middle main chamber and four longitudinal chambers which are arranged offset with respect to one another over the circumference of the main chamber. Wall portions of the main chamber which are situated between the longitudinal chambers are removed, and the extruded profile is severed into two semifinished parts. Each semifinished part has one cylinder portion and two oppositely situated arm portions which project relative to the cylinder portions. The semifinished parts are subsequently mechanically machined, and one spring strut fork is produced from each semifinished part.

Provided are a method for machining the outer circumference of a metal end cross-section, the method being capable of easily forming at least any of a deep groove, a deep recess, and a flange which are smooth and uniform in the longitudinal direction of a metal rod or metal pipe in the periphery of the cross-section of any of the end part of the metal rod or metal pipe, the drawn end part of the metal rod or metal pipe, and the hub hole forming part of the metal pipe; and a method for joining a metal component obtained by the machining method with another member. The machining method of the present invention is characterized in that: splitting is advanced by successively repeating press forming operation multiple times by using a slitting punch, in which a tip part has a sharp cutting edge, and the cutting edge is formed so as to have a shape equal to or partly equal to the outer shape of the cross section of a metal end part and so as to have a diameter smaller than the outer diameter of the cross section of the splitting object; and in order to control the depth of metal cracking cleft created with each press forming operation, a pressing die for pinching the outside of a metal rod or at least a pressing die of one side of pressing dies for pinching the inside and the outside of a metal pipe is disposed while its position is moved according to the distance of a split portion.
