Safety Protocol

Theoretical Limits and Operational Safety

This application calculates tonnage based on "Air Bending" principles. "Bottoming" or "Coining" operations may require 3 to 5 times more tonnage than these values.

Calculations assume homogeneous material. In actual production, material quality, grain direction, temperature, and operator experience may affect results.

Tool Life

Excessive tonnage can cause tool breakage.

Machine Deflection

Check crowning requirement for accuracy.

Safety Factor

Always add 20-30% safety margin.
