The present invention provides lift pin strategies with a reduced risk of causing contamination due to the up and down actuation of lift pins. The present invention provides a lift pin system that uses electromagnetic actuation strategies in order to raise and lower lift pins. The electromagnetic forces act remotely on the lift pins so that direct contact or coupling of the lift pins to actuation components is not required. This avoids contamination that otherwise would be associated with friction and associated lubricants used for mechanical actuation strategies.

Aspects are provided for retaining components of an assembly to a support, including additively manufactured (AM) parts of a vehicle chassis to an assembly table. A cartridge for securing the component to the assembly table is provided which includes a housing including at least one compartment, an adhesive disposed within the at least one compartment, a fastener removably attached to the assembly table, and a membrane lid enclosing an opening of the housing. The membrane lid is configured to receive a protruding member from the component such that the protruding member becomes adhered to the adhesive upon penetrating the membrane lid. The cartridge thus allows the component to be quickly retained in any selected position while constraining movement of the component along six degrees of freedom, thereby allowing AM and non-AM parts to be securely retained to accommodate strict tolerance and precise fit between the components of the assembly.

A machining support configured to reduce spring back of a sheet following a machining operation on the sheet is presented. The machining support comprises a porous material with a plurality of surfaces including a support surface having a contour configured to contact and support the sheet; sealing material covering each of the plurality of surfaces except the support surface; and a vacuum port configured to provide a vacuum to the porous material.

A clamp (100) applicable to a tyre (P) on a vehicle wheel and comprising a body (10) that includes a plurality of arms (11) extending radially from a central axis (X) and angularly distributed about the central axis (X) and a plurality of sliders (20), each slidably coupled to a respective arm (11) to move radially between a retracted position and an extracted position. The clamp (100) also comprises an manoeuvring member (30) connected to the body (10) and a plurality of connecting levers (40) having a first end that is articulated to the manoeuvring member (30) and a second end (40b) that is articulated to a corresponding slider (20) of the plurality of sliders (20) so that a movement of the manoeuvring member (30) corresponds to a movement of the sliders (20). The clamp (100) also comprises a locking device (50), movable between a locked position and an unlocked position, and a handgrip (60) integral with the manoeuvring member (30) and grippable by a user to directly move the manoeuvring member (30) about the central axis (X).
