In order for the effect of the step bending to be satisfactory, it is necessary to perform certain calculations, which, however, require knowledge of several of the most important parameters related to the bending process – these are:

• Arc length – the distance between the ends of the curve of the bent part of the sheet metal, counted on the inside of the bend;
• Number of bends – the number of individual bends that must be performed to obtain a bent sheet metal with a specified radius; the greater the number of bends, the smaller the angle of a single bend and, as a result, the smoother the arc;
• Distance between bends – the distance between individual bends made during the process.

Selecting a matrix and a punch 

Due to the final effect, the appropriate selection of press brake tools, i.e. the die and the punch, is also important.

Although the entire step bending process may seem quite complicated, the machines and software available from CORMAK are already so advanced that in many respects they completely replace the operator.

CORMAK press brakes continuously measure the bending process and can, for example, correct deviations during the process to achieve the most optimal effect.
