Procedure

1. Clean the Stamping Press and Work Area
   Ensure that the press bed, ram, and surrounding workspace are free from dust, metal scraps, oil spills, or previous material residues. This prevents improper seating of the die and ensures safe operation.

2. Inspect the Machine and Tooling
   Check the press for proper functioning, including lubrication levels, electrical connections, emergency stop button, and safety guards. Inspect the punch and die for wear, cracks, or damage before installation.

3. Mount the Die on the Press Bed
   Place the die block securely on the press bed (lower bolster).

   • Align it with the T-slots provided on the bed.
   • Use appropriate bolts and clamps to fasten it tightly.
   • Ensure the die surface is level and firmly seated to prevent vibration during operation.

4. Fix the Punch in the Upper Ram
   Attach the punch to the ram (upper slide) of the press using the punch holder.

   • Tighten all fastening bolts properly.
   • Ensure the punch is centered with respect to the die opening.

5. Align the Punch and Die
   Slowly lower the ram manually (using jog mode) to check alignment.

   • Ensure the punch enters the die cavity smoothly without interference.
   • Adjust position if any rubbing or misalignment is observed.
     Proper alignment prevents tool damage and defective components.

6. Set Stroke Length and Press Tonnage

   • Adjust the stroke length according to the thickness of the sheet and depth of operation.
   • Set the required press tonnage based on material type and thickness.
   • Ensure that the applied force does not exceed the rated capacity of the press.

7. Prepare the Sheet Metal Specimen

   • Cut the sheet to the required blank size (if not pre-cut).
   • Remove burrs or sharp edges from the sheet.
   • Clean the sheet surface to remove dirt, rust, or scale.

8. Apply Lubricant
   Apply a thin, uniform layer of suitable stamping lubricant on the sheet surface.
   This reduces friction, prevents tearing, improves surface finish, and increases tool life.

9. Position the Sheet Metal
   Place the sheet metal carefully over the die cavity.

   • Ensure correct orientation.
   • Use guide pins or stops (if available) for accurate positioning.
   • Keep hands clear from the punch area.

10. Start the Press Machine
    Switch on the main power supply.

    • Ensure safety guards are in place.
    • Stand at a safe distance from moving parts.

11. Perform the Stamping Operation
    Activate the press using the control button or foot pedal.

    • The ram moves downward.
    • The punch applies compressive force on the sheet.
    • The material undergoes plastic deformation and takes the shape of the die cavity.

12. Allow Complete Stroke and Retraction
    Allow the punch to complete the full stroke cycle.

    • After forming, the ram automatically returns to its original position.
    • Do not attempt to remove the component until full retraction occurs.

13. Remove the Stamped Component
    Carefully remove the formed part from the die.

    • Use tools if necessary (do not handle sharp edges carelessly).
    • Remove scrap material if generated.

14. Measure the Component Dimensions
    Use a Vernier caliper or micrometer to measure:

    • Length
    • Width
    • Thickness
    • Hole diameter (if piercing operation)
      Compare measured values with design specifications.

15. Inspect for Defects
    Examine the component visually and dimensionally for:

    • Burr formation
    • Cracks or fractures
    • Wrinkling
    • Distortion
    • Surface scratches

    Record all observations in the lab manual.
