Sheet metal bending collision is an unwanted aspect of the process wherein the sheet metal touches another surface apart from the die. Solera Metal Fabrication, a major metal fabrication facility in Brampton, Ontario, explores some common causes behind collisions during sheet metal bending services in this blog.
What Are The Common Causes Of Sheet Metal Bending Collisions?
Collision With The Brake
This occurs when the geometry of the sheet metal part being bent comes in contact with the press brake. The most common causes include:
- Improper bending sequence that causes the bends before to hinder later bends during the fabrication process. With a proper sequence, however, this sheet metal bending error can be easily avoided.
- In some cases, the part geometry can be too complex, and the machine’s capability is limited and not designed for multiple bends beyond a certain point.
Self-Collisions
As the name suggests, self-collisions occur when the parts of the sheet metal being bent come into contact with each other, interfering with the overall process. Common causes include:
- Inadequate spacing between each bend is the most common cause. This can easily be avoided by bending sheet metal in a professional manner.
- Similar to a collision with the brake, incorrect bend sequencing can also lead to self-collision.
Conclusion
To summarize, collision with the brake and self-collisions are the two most common errors when bending sheet metal. The most common cause is improper bend sequencing, which can be avoided with meticulous design and planning.

FAQs:
How to choose a bend radius for softer metals?
For softer metals, choose a bend radius that is equal to the thickness of the metal part.
Can a CNC brake press reduce errors during sheet metal bending?
Yes, a CNC brake press can reduce errors during sheet metal bending as the process is automated, ensuring a high degree of accuracy.
