Verifying the Accuracy of the Calibration

After completing the calibration process for the press brake machine, it is crucial to verify the accuracy of the calibration to ensure that the machine is functioning correctly. This step is essential to prevent any inaccuracies or errors in the bending operations. Here are a few procedures to follow for verifying the calibration:

  1. Test Bends: Perform test bends on different materials and thicknesses to assess the accuracy of the machine’s bending angles and dimensions. Measure the angles and dimensions of the test bends using precision measuring tools such as angle gauges and calipers. Compare the measured values with the desired angles and dimensions to determine if the calibration is accurate.
  2. Sample Bends: Take a sample workpiece and perform multiple bends using the calibrated press brake machine. Inspect the quality and consistency of the bends by checking for any variations or defects. Measure the angles and dimensions of the sample bends and compare them with the required specifications. Any significant deviations may indicate a need for recalibration.
  3. Tolerance Checks: Verify that the machine’s bending tolerances are within the specified limits. Use precision tools to measure the actual dimensions of the bends and compare them with the allowed tolerances. If the measured dimensions fall outside the acceptable range, adjustments may be needed in the calibration process.
  4. Repeat Checks: It is important to periodically repeat the verification process to ensure continued accuracy of the press brake machine’s calibration. Regularly check the machine’s performance and compare it with the initial calibration results. This will help identify any potential drift or changes in the calibration that may require adjustment.
