R_m - tensile strength, MPa;

Find the force (F) needed for guillotine cutter to chop metal sheet. The thickness of material is 2 mm and tensile strength is 203 MPa. The angle between the blades of the cutter φ is 7 degrees.

where s - thickness of material, mm;

τ₁ (tau) - material's shear strength, MPa;

φ (fi) - the angle between the blades of the cutter (usually 6-8 degrees).

Provide answer in Newtons.

Image failed to load: Automotive Parts Made by Closed Die Forging Process

Would you prefer forging or casting for following automotive components, and why?

Neither of them. Cutting technology would be the best because of high dimensional accuracy.

Casting. Technology provides good vibration damping properties of parts and is suitable for large production quantities.

Forging. Technology provides higher strength and better fatigue properties of parts.

Which technology would be best suited for production of following component?

Automated cutting. Enables production of complex shapes and large variety of materials can be used.

Casting. Suitable for complex-shaped products, good dimensional accuracy and can provide vibration damping.

Forging. Technology is best suitable for complex-shaped products and provides good surface quality and high strength.
