Gone are the days when a person or group of workers spend many hours cutting and polishing a single object to give it smooth finish and accuracy. With the advent of technology, this tiresome process has gone into oblivion.

Laser cutting, as the name suggests, deals with application of laser to cut various materials, mostly for construction and manufacturing industry. Though it sounds very high-tech and costly, it seems to have made its way into day to day life and has become an integral part of it. Hence, not only major industrial houses but also small scale business along with numerous schools and hobbyist use it nowadays.

Laser cutting deals with a powerful laser beam directed at the material that needs to be shaped as desired. This high power beam is controlled by a computer which is programmed before cutting process. This is done via CNC machining that uses computer aided design (CAD) and computer aided machine (CAM) technology.

CO₂ laser, which is one of the three types of lasers used in laser cutting process, is mostly suitable for cutting, boring and engraving. The other two laser types are Neodymium (Nd) and Neodymium-yttrium-aluminum-garnet (Nd-YAG). Both differ in their application but are mostly same in style. At many places, laser cutting is also carried out using a laser micro-jet which is a water-jet guided laser. In terms of tolerance and surface finish, laser cutters have positioning accuracy of 10 micrometers and repeatability of 5 micrometers. Laser cutting machines generally operate at 1500 watts but in recent years machines with more than 6000 watts of power are being used. Various factors of laser cutting such as laser power, pulse frequency, type of gas, gas purity, nozzle and nozzle sizes vary according to need.

Over the years, laser cutting has grown its market share versus mechanical cutting which is very slow, sometimes inaccurate and has limited design variation. Laser cutting has only one disadvantage that is the high power consumption. But this process comes with a lot of speed and accuracy in work that this disadvantage is not worth mentioning. Laser cutting is carried out in an area called as Machine shop, where other manufacturing processes like Sheet metal fabrication, Metal stamping are also carried out.

Such is the phenomenon of laser cutting that many high industrial firms have opted to start laser cutting services for small firms that are not capable of having their own laser cutting system, thereby making such high efficient technology accessible to all sections of industry. Laser cutting is nothing but a shortcut to awesomeness, a result of human being’s perseverance to excellence.

Before 19th century, various machining processes were carried out with hand wheels or levers that required tremendous amount of human power and countless work hours. To compete with increasing industrial demands, such a slow pace of work was not viable for the organizations involved in contract manufacturing of industrial parts. With advent of computing technology and fusion of machining process with computer power, these complicated tasks have become a lot easier than ever. Thanks to the Computer Numerical Control machine tools, generally referred as CNC Machine tools for revolutionizing the machining processes.

In Numerical control, machine tools are operated with the help of abstract programs unlike mechanical automation where machines are controlled via cams alone. Along with Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) programs, modern CNC machines have made possible high level of automation in end-to-end component design. During the actual CNC machining process, these programs generate a computer file at first, and then a post-processor interprets this file to extracts commands needed to execute operations by a machine and in the last step, these commands are loaded into the machine. This work can sometimes be done automatically but sometimes requires some sort of human or robot interaction. At the end, going through complex procedures, a final product is produced that very closely resembles the actual CAD specifications and design.

A major part of CNC machine is the program which is a set of instructions for operation on body undergoing machining. Earlier, paper tapes were used for punching and storing instructions but now more mechanically robust Mylar tapes are widely used. Other storage devices like Floppy disks, USB drives and LAN's are mostly used in highly integrated environments. There are different CNC standards that have evolved over a long time period, are mostly based on vector graphic markup language supported by plotters. "G-code" standard was so popular that it became an EIA standard and is dominating CNC machine languages. Many machine/control tool manufacturing houses have developed their own proprietary programming methods that are more part-friendly and easy to implement. Recent developments have made use of logical commands (if/else statements), arithmetic and loop operations possible, and is know as microprogramming. As a result, these machines are more accurate than ever. Virtually any part can be programmed quickly and easily with conversational programming producing custom fabrication as ordered by different clients.

Various machining tools available with CNC variants are Drills, Milling Machines, Lathes, EDMs, Laser and water jets and Plasma cutters, Surface and Cylinder Grinders, and tools for metal fabrication. These machines have added consistency, accuracy, reliability and quality to highly integrated machining industry.
