Explain the Automation in Machining?
The word "automatic" is derived from Greek and it means "self-moving or "self thinking". The word "automation" has been used to refer to a type of manufacturing system in which the various manufacturing function such as material processing, material/part handling and inspection are carried out by self operating machine without human intervention. Automation is defined as any means of helping the workers perform their task more efficiency, by automation the operation are done uniformly and effectively which attain better accuracy and finish. Automation gives an opportunity to the worker to handle more than one machine in a given time. This raises the productivity. In automation the human participation is replaced by mechanical or electrical technologies. Basically, Automation is two forms:-
