The innovative Flex system is a dynamic control device to management the structural flexions during the bending and it allows to keep the same depth of fold whatever the length of the sheet metal.
The operation is based on the interpolation of data received from two pressure transducers places on cylinders and the deformation read by optical lines. During the testing phase it produces a table where pressure and deformation data are revealed.
In this way, without operator support, the CNC receives the data from cylinders pressure sensors, which are interpolated to define the correction to be made in order to ensuring so the same result both bending a long sheet and a short one, speeding up greatly the production cycle.
