The calculation of the cycle time of a process of automatic bending is a very complex operation because of the high number of involved variables.
For this reason the accuracy of the estimated time is inversely proportional to the number of folds and the superficiality of approach to computing.
Errors in the estimate of the real execution speed of the robot and the press, of the bending sequence and palletizing can greatly affect on the estimated value of the cycle time.

In this discussion the cycle of the bending process is divided into 3 phases: here we indicate the methodology to determine the duration of each single phase.
The total time of each phase will define the theoretical total cycle time of execution.
To define the actual cycle time of execution of the piece you will need to use some correction factors that take into account the different characteristics of the piece.
