Saitin saurin ciyarwa na inji: F = n × m × FN

 

F: saurin ciyarwa (mm/min)

 

M: adadin yankan gefuna

 

FN: yankan adadin kayan aiki (mm / juyin juya hali)

 

Saitin adadin kowane gefen: FN = Z × FZ

 

Z: adadin ruwan wukake na kayan aiki

 

FZ: yankan adadin kowane gefen kayan aiki (mm / juyin juya hali)
