We are a Belgian manufacturer of welding machines.
We are now buying complete programmed computers from third parties. We want to develop our own software on a B&R plc with stepper motor. Complete with a HMI (human machine interface) where the customer can add his design to be plasma cutted. Other parameters like thickness, cutting speed, gasses,... can easily be altered. On the display the customer can follow the parts that are already cut, and still need to be cut (red/green line on the drawing). When the arc for some reason is lost. We can travel back in the G-codes and resume the program.
