A rotary position sensor assembly (10) for detecting the angular position of the rotor (104) of a motor. The assembly (10) includes at least one sensor (12) and a sensor target (14) which is moveable relative to the sensor (12). The sensor target (14) comprises a tubular body (16) with a plurality of integrally-formed radially-extending sections (18). These sections (18) include two radial upper edge portions (24) which are supported by a radially-extending support which is set back from the edge portions (24). Each of the two upper edge portions (24) provide a target for the sensor. A sensor target (14) for use in a position sensor assembly (10), a method of production of the sensor target (14), and an electromechanical actuator which utilises the rotary position sensor assembly (10) are also provided.

A punch press includes a die, a punch, a support that supports the punch, a shifting member, and a rotating mechanism. The shifting member includes an opposing surface that opposes the punch. The shifting member is movable toward and away from the die together with the support and the punch and rotatable about an axis extending in a direction in which the shifting member moves toward and away from the die. The shifting member includes a recess in the opposing surface. The rotating mechanism rotates the shifting member about the axis to shift the shifting member between an abutment position where the basal end surface of the punch is abut against the opposing surface and a retraction position where the basal end surface of the punch is retracted into the recess.

A numerical controller controlling punching performs punching according to a machining program, detects a phenomenon that the punching is not normally completed, collects and stores information required for re-execution of a block in which the phenomenon is generated, and restores a machining state at the time of occurrence of the phenomenon and further re-executes the punching by using the information.

A cross bar for powder coating and electronic coating, and methods for forming the same. A connector extends between a front portion and a rear portion. Embosses are located in the front and rear portions to connect with each other. Drain holes are provided at spaced intervals along the front and rear portions, offset from one another.

A metal sheet with attachment points for attaching the metal sheet to a support structure has a contour cut introduced in a sheet surface of the metal sheet, wherein the contour cut extends transversely to a connection line extending between a first and a second one of the attachment points. The contour cut is positioned relative to the first attachment point such that a vibration line extending as far as the first attachment point when the contour cut is not present is interrupted by the contour cut.

A punching apparatus according to the present disclosure includes a punch and a die for forming a punching die for punching a predetermined shape from a workpiece, and performs a punching process for punching a shape of the punching die by the punch from the workpiece positioned on the die, the punching apparatus including a detection device and a determination device. The detection device includes measurers and acquires a horizontal component force generated in a direction of each of two axes orthogonal to each other in a plane orthogonal to an axis along a punching direction of the punch, among forces generated when the workpiece measured by the measurers is punched. The determination device determines whether or not a defect occurs in the punch or the die based on the horizontal component force acquired by the detection device.

A method of manufacturing a perforated sheet which has at least one hole. The method includes introducing at least two spaced boreholes into a sheet, the at least two spaced boreholes being formed so that they each pass through a thickness of the sheet, introducing a continuous cut between the at least two spaced boreholes in the sheet, and bending open a section of the sheet which is adjacent to the continuous cut so as to form a hole.

A punch head comprises a low profile hydraulic anvil piston with a punch across from a die on opposite sides of a gap between two legs. One of the legs comprises a position sensor disposed on the bottom of the leg. For example, a plurality of punch heads are disposed on a jig or frame and are positioned using one or more of the position sensors. For example, the position sensor is a mini fiber optic position sensor mounted in a recessed portion at the bottom of one or more of the punch heads.
