V-Opening Calculator

This V-Opening Calculator helps you find the recommended minimum, optimal, and maximum V-opening sizes based on your sheet thickness. It ensures clean, accurate bends while protecting tooling and reducing trial-and-error during press brake setup.

  • Sheet Thickness (mm): Enter your sheet metal thickness to calculate suitable V-opening values for safe and precise bending.
  • Minimum V-Opening (mm): The smallest safe V-opening for your sheet thickness.
  • Optimal V-Opening (mm): The recommended V-opening for best bending results.
  • Maximum V-Opening (mm): The largest usable V-opening while maintaining bend quality.
