1. Use proper safety equipment such as gloves and eye protection when bending steel to prevent injury.
2. Determine the type of steel you are working with, as different types of steel have different properties that may affect the bending process.
3. Use a bending machine or a hydraulic press to bend steel, as these tools provide the necessary force to bend the metal without damaging it.
4. Make sure to properly secure the steel in the bending machine or press to prevent it from slipping or moving during the bending process.
5. Start the bending process slowly and gradually increase the pressure to avoid putting too much stress on the steel, which can cause it to crack or deform.
6. Use a bending die or jig to achieve the desired bend angle and shape accurately.
7. Check the steel for any cracks or deformities after bending to ensure that it has been bent properly.
8. Practice proper maintenance of bending tools and equipment to ensure they are in good working condition for future use.
9. Consider seeking professional help or training if you are unsure about how to bend steel properly to avoid damaging the material or causing injury.

Steel Bending Notes
Purpose:
- To provide clear instructions for bending steel bars or plates to specific shapes or angles.
General Guidelines:
- Ensure that the steel material is suitable for bending, such as mild steel or stainless steel.
- Use a bending machine or brake that is appropriate for the thickness and size of the steel.
- Calculate bending radii and allowances based on material properties and design requirements.
- Lubricate the bending surfaces to reduce friction.
- Heat the steel if necessary to facilitate bending without cracking.
- Follow safety precautions, such as wearing protective gear and ensuring proper machine setup.
Notation:
- L: Length of the flat part before the bend
- R: Bend radius (distance from the inside surface to the neutral axis)
- A: Angle of the bend
- ML (or ML1 and ML2): Measurement from the start of the bend to the inside surface of the flange
- K: Constant based on material properties and bending method
Bending Formulas:
- Outside Flat Length (OFL): OFL = K - R
- Inside Flat Length (IFL): IFL = L - 2 - OFL
- Length of Bend (LB): LB = A - R
Bending Diagrams:
- Three-Point Bending:
- OFL = R
- IFL = L - 2 - R
- LB = A - R
- Air Bending:
- OFL = 1.17 - R
- IFL = L - 2.34 - R
- LB = A - R
- Roll Bending:
- OFL = 1.45 - R
- IFL = L - 2.9 - R
- LB = A - R
Example:
Bend a 10 mm thick, 100 mm wide steel plate to a 90-degree angle with a bend radius of 50 mm using three-point bending.
- OFL = R = 50 mm
- IFL = L - 2 - OFL = 100 mm - 2 - 50 mm = 0 mm
- LB = A - R = 90 - 50 mm = 4500 mm
Additional Notes:
- Bends that are close to a flat part may require a setback allowance.
- Include any additional bend notes, such as tolerances, welding requirements, or surface treatments.
- Review and approve bending notes with the fabricator before production.
