The process of carrying out an industrial task usually involves many recurring steps. These steps can be carried out manually or automatically. In the manual system, an operator is always present to decide every process step. In the automatic system, the process controls itself, partially or entirely, by the feedback of its condition. Therefore, an automatic system can be semi-automatic or fully automatic.
In semi-automation, a machine automatically carries out several recurring partial steps in processing a workpiece. Here, an operator is required to initiate every cycle of operations.
In complete automation, a machine automatically performs cyclic operations to process several jobs. Sensors and/or transducers are invariably used in automatic control systems.
