As we know in CNC machine various operations are done the basic process is we give input like raw material then it will do various process on it and finally we will get the output here we will understand about open loop system in open loop system the process is same like Input, process & output in open loop system there is not a feedback device so if the output is ready and if it is accurate or not or any problem came in it we will not be able to know in open loop system because there is no feedback device this is known as open loop system. Figure of open loop system is shown below.
As shown in figure there is no feedback device this is known as open loop control system.
Closed loop system
The main thing in closed loop system is that there is a feedback device so if any problem during operation or in output the feedback device will give feedback to the error signal so we can make changes in it so now we we get the accurate product without any defect this is know as closed loop system. Figure of closed loop system is shown below.
In this figure we can see that there is a feedback device that goes to error signal so we are able to know that some problem is there and we can correct it this is known as closed loop systems.
