The punching processing method of the present invention is a punching processing method in which a metallic sheet material 1a is sequentially subjected to multiple punching processing steps by a punch and a die, comprising, in first step punching processing, forming a first step punched surface 2 on the sheet material 1a, and then in second step punching processing, forming a second step punched surface 3 on the sheet material 1a by punching the sheet material 1a such that the second step punched surface 3 and the first step punched surface 2 are crossed with each other, thereby forming matching portions 5 at positions where the first step punched surface 2 and the second step punched surface 3 intersect, wherein after the first step punching processing and before the second step punching process, the method further comprises subjecting the sheet material 1a to swaging processing that sandwiches and crushes matching portion forming portions 5a of the sheet material 1a, which will form the matching portions 5, from a top surface TS side and a back surface BS side of the sheet material 1a.

There is provided a method of producing acoustic damping elements having an acoustic resistance. For that purpose at least one sleeve with a hole having a diameter is placed below a base material. At least one hole is stamped in the base material by at least one punch having a punch diameter. The punching operation is repeated at various positions on the base material.

A flat harness is machined by providing a punching machine that includes a first punching device and a second device, and forming different types of hole portions in the shape on the insulating portion of the flat harness in a die cutting process by using the first punching device and the second punching device.

A continuous punch apparatus comprises a first punch station and a second punch station. The first punch station includes a first punching assembly and a second punching assembly that are laterally spaced apart from each other. The first punching assembly and the second punching assembly are configured to be moved laterally. The second punch station includes a third punching assembly. The third punching assembly is configured as having a punch head with a cross-section parallel to a sheet material and increasing in a direction away from the sheet material, so that a substantial punching section of the punch head of the third punching assembly in punching through the sheet material can be selectively used.

A method of detecting an overall dimension of a plate-shaped workpiece to be processed on a processing machine by a contactless-acting sensor includes moving the workpiece by a motion device of the processing machine in a predetermined direction until the sensor detects a first workpiece edge by a first change of state, detecting a first position of the workpiece where the first change of state happens by an evaluation device connected to the sensor, moving the workpiece by the motion device in a direction toward a second workpiece edge until the sensor detects the second workpiece edge by a second change of state, detecting a second position of the workpiece where the second change of state happens by the evaluation device, and determining an overall dimension of the workpiece by a determination of a distance between the first position and the second position of the workpiece.

A method for machining a plate-like workpiece with a processing machine includes forming a receptacle in the plate-like workpiece for an insert part and machining the receptacle based on one or both of an orientation at which the insert part is to be inserted into the receptacle and a side of the plate-like workpiece from which the insert part is to be inserted into the receptacle. The method further includes running a machining program to carry out the forming and the machining of the receptacle. A computer program product is provided to configure a programming system by which the machining program is generated.

A drive device for a movement unit of a machine tool includes a first toothed element driven by a drive motor and provided as a drive pinion including a first tooth arrangement and a second toothed element provided as a toothed rack including a second tooth arrangement. One of the first and second toothed elements is connected to a machine frame, and the other of the first and second toothed elements is connected to the movement unit. The first and second toothed elements are moved relative to each other along a movement axis of the first and second toothed elements by the drive motor via a meshing between the first and second tooth arrangements and via an engagement between the first and second tooth arrangements along an engagement axis that extends perpendicularly to the movement axis.

The present method of forming a polar plate comprises: a stamping step: implemented by a stamping press, which includes a stamping tool mounted on a slider moved by vertical reciprocating movement; and during which a network of channels for circulating fluids is stamped on the strip; and a downstream step subsequent to the stamping step and implemented by a downstream press;
wherein: once the channel network is stamped on the strip, while the strip is held clamped in the stamping tool, a reference mark is formed on the strip by means of a marking tool carried by the slider; and during the downstream step, the strip is positioned with respect to the downstream press by means of positioning members mounted on the downstream press and which cooperate with the reference mark.

Press tool holder (10), comprising a press tool attachment (11) extending in the longitudinal direction (L) and a primary tool adjustment (20), wherein the press tool attachment (11) serves to hold a press tool (100), wherein the primary tool adjustment (20) has an X-direction adjustment (22) and Y-direction adjustment (24), wherein the X-direction adjustment (22) enables a change in position of the press tool (100) in the X-direction (X), wherein the Y-direction adjustment (24) enables a change in position of the press tool (100) in the Y-direction (Y), wherein the X-direction adjustment (22) is independent of the Y-direction adjustment (24), wherein the X-direction (X), the longitudinal direction (L) and the Y-direction (Y) are each perpendicular to one another.
