## Abstract

A clamshell die press includes a fixed platen, a moving platen installed thereon a cutting blade, and a pad mounted on top of a working surface of the fixed platen, wherein the pad comprises a padding block, wherein the padding block comprises a padding layer composed of a material selected to match a tooth profile of the cutting blade.

## Claims

### Claim 1

A clamshell die press system, comprising:
a clamshell die press comprising:
a fixed platen; and
a moving platen; and
accessory parts to be installed on the clamshell die press, the accessory parts comprising:
a cutting blade set comprising a first cutting blade having a first tooth profile, and a second cutting blade having a second tooth profile, wherein the first tooth profile is different from the second tooth profile, and one of the first cutting blade or the second cutting blade is to be installed on the moving platen; and
a pad set comprising a first padding block comprising a first padding layer composed of a first padding material having a first Shore value, and a second padding block comprising a second padding layer composed of a second padding material having a second Shore value, wherein the first Shore value is different from the second Shore value, one of the first padding block or the second padding block is to be mounted on a working surface of the fixed platen, the first padding block is paired with the first cutting blade, and the second padding block is paired with the second cutting blade, and the first and second Shore values represent a respective hardness measurement of the corresponding first and second padding materials.

### Claim 2 (depends on 1)

The clamshell die press system of claim 1, wherein each of the first padding block and the second padding block further comprises a backing layer bonded to the first padding layer and the second padding layer, respectively, and wherein the backing layer comprises a sheet of metal.

### Claim 3 (depends on 2)

The clamshell die press system of claim 2, wherein the first and second padding layers comprise at least one of Urethane, rubber, or ultra-high-molecular-weight (UHMW) polyethylene, and wherein the backing layer comprises a sheet of steel.

### Claim 4 (depends on 2)

The clamshell die press system of claim 2, wherein the sheet of metal of the backing layer is magnetized steel, and wherein the first or the second padding block is bonded to the working surface of the fixed platen via magnetic force.

### Claim 5 (depends on 2)

The clamshell die press system of claim 2, further comprising a double-sided magnetic layer mounted on the working surface of the fixed platen, wherein the padding block is secured, via magnetic force, to the double-sided magnetic layer that is secured, via magnetic force, to the working surface of the fixed platen.

### Claim 6 (depends on 1)

The clamshell die press system of claim 1, wherein the tooth profiles associated with the first cutting blade and the second cutting blade each comprises parameters representing a tooth pitch, a gullet depth, a tooth contour shape, and a valley contour shape, and wherein one of the padding layers with a softer padding material is paired with one of the cutting blades with a larger gullet depth.

### Claim 7 (depends on 6)

The clamshell die press system of claim 6, wherein the tooth profile of one of the cutting blades is to be installed on the moving platen based on a material composition of the work piece being cut by the one of the cutting blades.

### Claim 8

A method comprising:
determining a material composition of a work piece to be machined on a die press device;
selecting, based on the material composition of the work piece, a first tooth profile of a first cutting blade installed on the die press device;
selecting a first padding block that comprises a first padding layer composed of a first padding material having a first Shore value wherein the first cutting blade is paired with the first tooth profile;
mounting the first padding block on a working surface of the die press device;
responsive to replacing the first cutting blade with a second cutting blade having a second tooth profile, selecting a second padding block that comprises a second padding layer composed of a second padding material having a second Shore value, wherein the second cutting blade is paired with the second tooth profile, and wherein the second Shore value is different from the first Shore value, and the second tooth profile is different from the first tooth profile; and
mounting the second padding block on the working surface of the die press device.

### Claim 9 (depends on 8)

The method of claim 8, further comprising operating the die press device to machine the work piece into a product.

### Claim 10 (depends on 9)

The method of claim 9, wherein the tooth profiles associated with the first cutting blade and the second cutting blade each comprises parameters representing at least one of a tooth pitch, a gullet depth, a tooth contour shape, or a valley contour shape, and wherein the padding layer with a softer padding material is paired with one of the cutting blades with a larger gullet depth.

### Claim 11 (depends on 9)

The method of claim 9, wherein the first padding block further comprises a backing layer bonded to the first padding layer, and wherein the backing layer comprises a sheet of metal.

### Claim 12 (depends on 11)

The method of claim 11, wherein the first and second padding layers comprise at least one of Urethane, rubber, or ultra-high-molecular-weight (UHMW) polyethylene, and wherein the backing layer comprises a sheet of steel.
