Cycle Time
Cycle time is how long a robot takes to complete one full operation. It drives throughput and is the key productivity metric for an automation cell.
Cycle time is the total time a robot needs to complete one repetition of its task — pick, move, place, and return. It directly determines throughput (parts per hour) and is the number most automation business cases are built on.
Cycle time depends on path length, robot speed and acceleration, payload, gripper action, and any waiting on machines or signals. Real cycle times are usually longer than catalogue 'move' times because they include tool actuation and synchronisation.
When sizing a used robot for a target rate, validate cycle time with a simulation or trial, not just the spec sheet. A faster SCARA or delta robot may beat a six-axis arm on flat, repetitive work.
