Laser cutting and bending processes often used together to create a final product.
To successfully use these two independent processes it is necessary to modify the machine programs to achieve and accurate final result.
- Bending laser cut parts
BLM offers an effective solution for identifying laser cut features on a tube in order to correctly reference the part for bending. The system “reads” the presence of holes, slots, seams in a simple and reliable way.
- Cutting of already bent parts
The LT-FREE 5 axis cutting system is suitable for the processing bent, hydroformed, or preassembled tubes, as well as flat or stamped sheet metal parts. The system is perfect for laser cutting or trimming on any three dimensional part.
- Curved tube management
• Import 3D models of both bent and laser-cut tubes
• Automatically generate the part-program for the different technologies (laser, sawing and bending)
• Calculate the combined effects of the laser cutting and bending
• Automatically correct the programs to move laser cut features to compensate for bending in order to ensure the correct final part geometry.
Through the use of test bends and subsequent optimizations you can compensate for the tube elongation created while bending. However, you must manually edit the laser cutting program to make sure that the cutting geometries are in the correct final position. All this takes a lot of time and creates considerable scrap.
BLM GROUP machines are designed to communicate with each other.
With BLM GROUP machines, it is possible to import the 3D models of the product, both bent tubes and laser-cut tubes, and automatically generate programs items for all of the technologies involved (laser, sawing, bending).
The laser cutting and bending programs will interact and implement corrections needed to meet the geometric tolerances for the end product.
Full automation of programming for the entire process. Elimination of the trial and error testing required to adjust the programs. Reduced reliance on operator skills. Repeatability and precision of the final parts. No rejected items.
