## Abstract

Tooling for engaging with a workpiece has a body and a spring section formed as a monolithic structure from a resilient material. At least three deformable arms connect a movable shuttle to the body, the arms being configured to enable constrained movement of the shuttle relative to the body.

## Claims

### Claim 1

Tooling for engaging with a workpiece, the tooling comprising a body and a spring section formed as a monolithic structure from a resilient material, the spring section comprising:
a shuttle; and
at least three deformable arms each connected between the shuttle and the body;
the tooling further comprising an engagement member carried by the shuttle, for engaging with a workpiece in use,
wherein the arms are configured to enable constrained movement of the shuttle relative to the body, and
wherein the deformable arms are elongate, with their major arm axes arranged in parallel, to constrain movement of the shuttle to a translation along a movement axis orthogonal to the arm axes and parallel to a plane containing the arm axes.

### Claim 2 (depends on 1)

The tooling of claim 1, wherein the spring section comprises four deformable arms.

### Claim 3 (depends on 1)

The tooling of claim 1, wherein at least two of the deformable arms are spaced apart along the movement axis, and at least two of the deformable arms are spaced apart in a direction parallel to the arm axes.

### Claim 4 (depends on 1)

The tooling of claim 1, wherein the engagement member comprises a pin mounted to the shuttle.

### Claim 5 (depends on 1)

The tooling of claim 1, wherein the engagement member comprises a surface of the shuttle for engaging with a side of the workpiece.

### Claim 6

A carrier arrangement for carrying at least one workpiece, comprising:
a carrier; and tooling for engaging with a workpiece, the tooling comprising a body and a spring section formed as a monolithic structure from a resilient material, the spring section comprising:
a shuttle; and
at least three deformable arms each connected between the shuttle and the body;
the tooling further comprising an engagement member carried by the shuttle, for engaging with a workpiece in use,
wherein the arms are configured to enable constrained movement of the shuttle relative to the body, and
wherein the deformable arms are elongate, with their major arm axes arranged in parallel, to constrain movement of the shuttle to a translation along a movement axis orthogonal to the arm axes and parallel to a plane containing the arm axes.

### Claim 7 (depends on 6)

The carrier arrangement of claim 6, wherein the tooling is attached to the carrier.

### Claim 8 (depends on 6)

The carrier arrangement of claim 6, wherein the carrier, body and spring section are formed as a monolithic structure.

### Claim 9 (depends on 6)

The carrier arrangement of claim 6, comprising a plurality of toolings, for engaging with respective workpieces.

### Claim 10 (depends on 9)

The carrier arrangement of claim 9, comprising a plurality of frames for accommodating individual respective workpieces, each frame being at least partially defined by a respective tooling.

### Claim 11 (depends on 10)

The carrier arrangement of claim 10, wherein each tooling is aligned in the same orientation, and wherein the carrier comprises an actuation plate in cooperative engagement with the shuttle of each tooling, such that movement of the actuation plate in an opening direction causes the shuttle, and hence engagement member, of each tooling to move relative to the respective body and enlarge the respective frame.

### Claim 12 (depends on 11)

The carrier arrangement of claim 11, comprising an actuator for moving the actuation plate in the opening direction.

### Claim 13 (depends on 12)

The carrier arrangement of claim 12, wherein the actuator comprises a cam screw.
