The factor that guarantee aircrafts safety standards originate from a process called CAD/CAM. "CAD" stands for Computer Aided Design while "CAM" is the short form for Computer Aided Manufacture. Before anything gets manufactured, airplane parts such as the tail, wings and cockpit are artificially designed in computers in order to preview it. Therefore, it is like a stimulator to observe the consequences of the behaviors of the materials under certain circumstances. During the CAD process, architects would transfer construction drawings into the computer. From there the operator would have to use knowledge of engineering maths to design the 2D and 3D designs of all the required materials. Furthermore, aspects such as the reliability and security will be tested to evaluate the quality of the output.
After the designs have been proven proper for its usage, the process of "CAD" will take over. The transformation from "CAD" and "CAM" is through software called "Mastercam" (developed by CNC Software.inc). Based on the final product from "CAM", engineers would then create sets of instructions for computers on how to produce the prototypes. By utilizing Mastercam, engineers would have the options ranges from surface pocketing to the creation of 3D and 2D objects.
There are many sophisticated and complex machining process a prototype has to go through and as technology advances, more and more methods are being introduced into the market for huge corporations such as GMC, Boeing and Airbus. The way mastercam works is; it displays materials in the screen computer and in order to modify the appearance. In today's world, options in mastercam software include drilling, pocketing, peel mill and many others. CNC's latest development now is involving reducing the amount of CO2 emissions during the process by improving the physical packaging of the product, and enhancing ways in which to save up energy and improve the efficiency of it. Because of this, man other major companies are turning green to attract engineering industries to purchase their product since the consumers of today are looking for merchandises that can delay the consequences of global warming and this can have a huge impact in the flow of the business world.

A. Presentation of the issue.

Air travel could be traced back from the early 20th century, however, it was an idea that really recieved the support by the society shortly after the first world war. Since then, the aviation industries had been expanding globally as a result of migration. Today, the biggest airline in terms of amount of carriers is known as the American Airlines, having more than 500 aircrafts in its fleet serving accross the United States of America. Also, in time, designs of aircrafts have greatly altered as technology advances everyday. However, as the world is facing constant economic crisis, airline industry can collapse as it has a very heavy reliabity on jet fuel. Currently, two airlines; Oasis and Alitalia have collapsed due to the shortage in profit due to the high oil prices. Therefore, more fuel efficient aircrafts are needed immediately to solve the current problem. Economic Analysts say that it is the only way to save the airline industry and keep it running for a long time since it is a very fragile business as it can cause large amount of unemployment as well as loss in income of airports if carriers collapse. This is where the use of CAD/CAM can help mankind to design more efficient aircrafts.
