Computer Aided Design; Changing the World we Live in

Computer Aided Design (CAD) and CAM machinery are found in all workforces, all over the globe. Many factory floors are now to be found almost entirely void from human interaction, robots working away quietly to produce hundreds of identical parts in the course of one day. The introduction of CNC machinery has enabled workforces to not just cut back on manpower but also to produce a higher quality of precision parts that are entirely free from human error. These parts are available to the consumer cheaper than hand made parts; so it really is a win-win situation whichever way you look at it.

CNC machining and milling does however require the precision of a trained CAD expert; this is where human intervention is still necessary and always will be. Behind every CNC lathe, drill, or machine there is a computer that is using CAD software to transmit the messages to the machine to tell it what to do. Behind that computer there is the software professional who programmed it, behind that the person who designed the software, and behind that the person who designed the computer in the first place.

From this point of view it is easy to see therefore that although a robot can carry out virtually any task required of it in the field of CNC engineering, highly trained professionals are required for the monitoring of these robots and ensuring they do what they are programmed to. On a factory floor you will see many CNC lathes, drills, and machines at work, and no one anywhere to be seen. Some setups are left to run overnight by themselves; this is made possible by the fact that on detection of an error by the computer, the CAD software will shut down the machine in question until an engineer comes along.


Computer aided design is used in almost all applications that you can think of in the modern world; from mass producing car parts to boring out metal tubes, CNC milling can carry out the tasks that it used to take the human being many hours to do. CAD software allows for further precision, and CAD design has somewhat put an end to hand drawings; with precise vector lines being used by CAD software once again the brains behind the design is present but the human error is not.

CNC is changing the world that we live in, it has been for some decades already, and it will continue to do so for many more. With every advance in technology, precision engineered parts can be made to higher specifications, with more complex designs, and without human error that occurred in the past. From something as simple as making a tin can perfectly round, to engineering aerospace parts, CNC machining is almost entirely responsible for the world in which we live today.
