To determine the required pump pressure ratings, we calculate the force needed for the punching operation using the cylinder's area and the applied force. The calculated pressure for deforming is approximately 5.88 MPa, so pump P2 should be rated for at least 6 MPa for safety. For the approach phase, where the load is minimal, a lower pressure of about 1 MPa is sufficient. This ensures the pumps operate efficiently and safely within required limits.
