Although it does not have a precise definition in the literature, it generally refers to the process of converting raw material into profiles over a unit of time. Broadly, it is calculated using four different methods:

1. Measuring the punch speed per unit time (mm/s).
2. Measuring the profile speed per unit time (m/min).
3. Measuring the net production quantity obtained per unit time (kg/h).
4. Measuring the gross raw material consumed per unit time (kg/h).
