When you leave on Friday afternoon, you start the automation. Before you even have time to begin your weekend activities Friday night, the cycle is already finished. Usually, you would have to come in on Saturday morning to set up the cycle again. But with automation, the machine just keeps loading itself and making parts. It could potentially run itself all weekend.
Nobody has to do anything.
It just keeps on going. Another issue addressed through automation is manpower. Because it is sometimes difficult to attract workers for the night shift, automation can assist since it allows unattended operation. This can make a shop more productive, potentially bringing more day shift work. With a skilled workforce being in high demand, this is key.
