A constraining assembly for a processing machine (1) is proposed that has a plate-shaped base (2) with at least one receiving hole (3) and at least one constraining bolt (4) for directly or indirectly constraining workpieces that are to be processed, wherein the constraining bolt (4) is placed in the receiving hole (3) in the base such that it can be removed therefrom, and wherein the base (2) has a receiving space (5) in which there is at least one actuating element (6) that can move axially, with which numerous lever elements (7) can be actuated to axially move the constraining bolt (4) in the receiving hole (3) in order to clamp and secure, or release, the constraining bolt (4). A constraining bolt (4) for a constraining assembly, as well as a processing machine (1) with such a constraining assembly, and a method for operating the constraining assembly, are also proposed.

The present invention discloses a flexible dot matrix bonding apparatus and an adaptive clamping method for a disk-type planar component. The apparatus mainly comprises three components: a substrate, connecting rods and an auxiliary support. The threaded holes in a circumferential array are uniformly distributed in the substrate, and the connecting rods are fixed at different circumferential positions of the substrate in a threaded connection manner, which play a role in bonding and supporting the disk-type planar component. The auxiliary support is matched with the substrate, so that a workpiece after turning can be taken out without damage. According to detection results of machining deformation of the disk-type planar component, the installation positions of the connecting rods on the substrate are adjusted accordingly, thus changing bonding positions of the disk-type planar component. Finally, an adaptive clamping method aiming at reducing the machining deformation of the disk-type planar component is formed.

A workpiece locational positioner apparatus that is compact for precisely positioning a workpiece from a position above a tool or fixture includes a cylinder assembly, a central (tip) cam plate adapted to convert the reciprocating motion of the cylinder assembly into a rotational motion, and an engagement package mounted to the cam plate, to accurately engage, position and locate the workpiece in the tool.

A system for post-cure processing a composite workpiece includes a tool. The tool includes a tool surface. The tool surface supports the composite workpiece located on the tool. The system also includes a drill template. The drill template defines a drilling location for drilling a hole through the composite workpiece while the composite workpiece is on the tool.

A system and method for processing a flexible part comprising holding the flexible part securely in an unconstrained position using a holder; and controlling a positioner to process the flexible part based on a comparison of a shape and/or position of the flexible part in the unconstrained position with design specifications of the part not in the unconstrained position.

A chuck grip accuracy checking method includes a gripping in which the measurement target is gripped on the claws, a moving step, and a measuring step. In the moving step, a movable member provided with a measurement instrument capable of measuring a run-out of the measurement target is moved by driving a movable-member driver to a position at which the measurement instrument can measure a run-out of the measurement target. In the measuring step, a run-out of the measurement target is measured by the measurement instrument, while the chuck is being rotated by driving a rotation driver.
