Reverse Engineering a Product

By Dayna Fields

The field of science goes hand-in-hand with the terms contract inspection and reverse engineering. Considering what we had just a decade ago, the large amount of work that you can achieve in a very small amount of time is incredible.

The process to reverse engineer something means that a scientist (or whoever) would dismantle a product with the intention of understanding how it was built in the first place. For example, one may take a part a computer chip and, using the same ideas from the original, rebuild it with different part than the original had.

The military uses this method often and they started as late back as the Second World War. For example, when the Americans noticed that the Germans had a better design for their gas tanks they sent out intelligence to gather some samples and then re-engineered the tank to fit their needs and created an even better model. Although the parts should all be different from the original model, the two products should essentially accomplish the same purpose. After a piece of equipment is finished being engineered, it must be inspected.

A laser rolls over the finished product and transfers the data to a computer. That data is much more sufficient and complete than any human can offer because their senses are simply limited. Whereas we once had to rely on human hands and eyes, we can now use a machine to inspect the finished creation for us.

If the product was assembled correctly, as seen by the data, then the product can be sent off to the field for use or to the manufacturing plant for mass production. It can only be after the data is transferred, however, that scientists can see exactly where there might be a problem or if all the parts of the machine, even the smallest parts in the hardest to see places, were installed correctly.

If so, then the product can be sent off to the field for use or to the manufacturing plant for mass production.

Bottom line, the thoroughness of the laser machine is far superior to what any human eye could offer in terms of information. In a matter of minutes, the computer can tell you exactly what and where there is a problem in the manufacturing of the product.

In many cases, ensuring that all the parts of an object were created and secured correctly is a matter of safety. And there is no better way of making sure of this than using a machine. Astronauts in the Space Station use this type of inspection as opposed to human inspection because it is important for them to be 100% positive that everything is installed correctly. - 22787
