Cutting clearance is the total gap between the upper and lower blades during the shearing process. It plays a crucial role in achieving clean cuts and minimiaing burrs.

📐 Formula:

Total Cutting Clearance = Material Thickness × Clearance Coefficient

• Material Thickness (t): The thickness of the sheet metal (in mm or inches).
• Clearance Coefficient (C): A coefficient based on material type and shearing method. Typical values:
  • Mild Steel: 6–10% (C = 0.06–0.10)
  • Stainless Steel: 8–12%
  • Aluminum: 4–8%
