Manually doing work is what humans what to
rise above for a long time. We want most of our work to be done by someone else
and also, we need it done perfectly. Relying on other people to do our task
seems like an attractive option but then the point about precision is doubtful.
We want work to be done as close to perfection as possible. This all started
when we made simple mistakes while adding big numbers and so we invented a
calculator that could do our work for us and we could also trust it about the
precision of working. This means we like to dictate the precision of work. This
must have been the source of cnc machining or computer
numerical control machining.
What is computer
numerical control machining?
Cnc machining is a process where the working of factory tools and
functioning of the entire factory is dependant on pre-programmed software. In a
factory, there is a lot of work to be done and it needs precision in
measurement or speed. All this work is kind of predictable and repetitive. So,
these can be made into programs for the computer to dictate the time of the
work to be done and at what speed it has to be done. Usually, in a factory,
these functions were carried out y workers with the help of manual operation of
levers or buttons. But now they are controlled by a set of software that decides
when to press the button or pull the lever up or down to get the work done. The
programming has to be done initially keeping all the components of the factory
in mind. Once the programming is done it is a much smooth sailing ship than the
factory that has to be manually operated and have more error factors.
A little about
the CNC programming
When it comes to CNC programming it can be
simplified into various aspects. This is a software that is able to do a job
based on the fact that everything is located right in the place where it is
supposed to be according to the program. The speed of the work to done can also
be adjusted in the pre-programmed software and the entire repetition can be
made easier.
Should you go with open loops or closed loops?
– an open loop is a one-way street from the controller to the motor. There is
no point of error correction in this one. A closed-loop on the other hand is
the one that gives the feedback from the motor to the controller and is
therefore capable of corrections.
cnc machining is a fully automated programming: there might be a need for
some robotic hands that will transfer the parts from one applicator to the
other and there has to be programming till the build-up of the finished product
but altogether this does a more precise job.
Sum it up
We can all see the obvious problem of cnc machining.
Due to most work done automatically and there is no need for manual help
the unemployment rates are going to go higher.
