A vibration damping system for machining parts uses magneto rheological radial squeeze film damper technology to reduce part vibration, enhance tool lifecycles, and to improve part surface finish. In the described embodiment, the damping system includes a pair of damping cylinders affixed to a machine tool fixture, each cylinder containing a solid core concentrically situated within an internal sleeve portion of the cylinder. Rheological fluid contained within a radial space between the core and sleeve defines a radial squeeze channel for the fluid. Fluid stiffness is controlled in real time by varying an electric current to modulate a magnetic field passing through the fluid to dampen vibrations in accordance with at least one predetermined algorithm. As material is removed from the part during machining, the fluid damping characteristics are actively managed by a machine tool controller as a function of a combination of dynamically changing and predetermined algorithmic inputs.

The invention refers to a chuck pallet (1.3) with solid groove-sidewalls (2.3) for clamping chucks (1.1), whereby the x-y-references (2.5) of the chuck pallet (1.3) are allocated in the same plane (2.1) as the z-references (2.1) and the x-y-references (2.5) are also allocated at the solid groove-sidewalls (2.3). The solid groove-sidewalls (2.3) have thereby a tapered profile.

An interface structure that is constituted by a first, U-shaped toothed pivot, which can be associated in an upper region, by way of a jaw connection, with a fixing element with the interposition of a first bush for centering. The first toothed pivot is rendered axially integral in a lower region with a fastening element that can be associated with an underlying device for compensating the misalignment in automatic locking systems for the mounting of blanks.

An assembly pallet is assembled a cell stack to. The cell stack that includes a cell group in which a plurality of electric cells are stacked, end plates arranged in a position between which the cell group is interposed, and a restraining member for applying a restraint that restrains the cell group to the end plates. The assembly pallet includes a positioning engagement member that is engaged with the restraining member to effect positioning of the cell stack.

A clamping jaw for clamping or holding a workpiece is described. The clamping jaw includes a base body and a clamping contour, which is provided for abutment against a workpiece and can be cooled by a cooling device. The cooling device is implemented by at least one coolant duct, which is provided for receiving a coolant and which is formed in the base body by a generative production (e.g., additive manufacturing) process. The formation of the base body is free of auxiliary bores. Furthermore, a method for manufacturing a clamping jaw is described.

Clamping device comprising a first connection body having a locking portion slidably inserted in a guide seat, which is obtained in a second connection body, so that the first and the second connection body are slidably associated to translate one with respect to the other in a plurality of adjustment positions. The locking portion is deformable between an expanded configuration, in which it exerts a pressure against a lateral surface delimiting the guide seat, and an undeformed configuration, in which it does not exert pressure allowing the first connection body to slide. A locking system is provided to act on the locking portion to deform it between the expanded and the undeformed configuration. Said locking system is moved by an actuating piston slidably inserted in a guide chamber obtained in the first connection body.

A mounting system having a dual plunger arrangement wherein the side of each plunger has a pull down cam to provide a desired pull down action in relation to at least two studs, the cams moving relative to one another and axially aligning relative to one another relative to the two axially spaced pull down studs to allow the plungers to provide a maximum hold down force for the two pull down studs, balance the hold down forces thereby maximizing performance and reducing unlocking forces.

Automated fixture layout is approached in two distinct stages. First, the spatial locations of clamping points on the work piece are determined to ensure immobility of the fixtured part under any infinitesimal perturbation. Second, spatial locations are matched against a user-specified library of reconfigurable clamps to synthesize a valid fixture layout or configuration that includes clamps that are accessible and collision free. The spatial locations matching during the second stage can be the same spatial locations chosen in the first stage to ensure immobility, or a different set of spatial locations.

A reconfigurable interface assembly includes, but is not limited to, a first sub-assembly that is adapted for attachment to a work-piece supporter. The first sub-assembly includes a first brake. The reconfigurable interface assembly further includes a second sub-assembly attached to the first sub-assembly. The second sub-assembly is adapted for attachment to a work-piece manipulator. The second sub-assembly includes a second brake. The first sub-assembly is configured to move the second sub-assembly in a first direction with respect to the first sub-assembly and the first brake is configured to inhibit movement of the second sub-assembly in the first direction with respect to the first sub-assembly. The second sub-assembly is configured to move the first sub-assembly in a second direction with respect to the second sub-assembly and the second brake is configured to inhibit movement of the first sub-assembly in the second direction with respect to the first sub-assembly.

The invention relates to a workpiece adapter apparatus for a machine tool to which at least one workpiece can be fixed and which can be fixed to a workpiece holding apparatus of the machine tool, comprising a holding body having a first side on which is arranged a first fixing device for the at least one workpiece and having a second side, opposite the first side, on which is arranged a second fixing device for fixing the holding body to the workpiece holding apparatus.
