As the name suggests, laser cutting machines are machines that use laser to cut materials. Initially only used for various industrial manufacturing applications, now a days these machines are also being used by schools, small businesses and hobbyists. A laser cutting machine used for commercial application generally comprises of a motion control system that precisely follows a CNC( G ? code) of the pattern that has to be cut.

Over the past few years, these machines have become the norm in many industries and are the preferred choice of a majority of users owing to their effectiveness, which cuts downtime at industrial facilities, thus increasing overall efficiency.
History of Laser Cutting Machines:
The first documented use of laser cutting machines was in the year 1965. A laser cutting machine manufactured by the western electric engineering research center was used for the purpose of drilling holes in diamond dies. Afterwards in the year 1967, the British made advancements in this machine and pioneered laser assisted oxygen jet cutting for metals. Gradual advancements in laser cutting machines took place and in the 1970's the machine was used for cutting titanium for use in the aerospace industry. Since then, these machines have evolved greatly and continue to do so even today.

Features of Laser Cutting Machines:
- A majority of laser cutting machines are designed with utmost emphasis given to ensuring their ease of usage and also optimal safety for the operator
- These machines work flawlessly in all weather conditions
- Laser cutting machines are manufactured from materials that are inherently resistant to corrosion, abrasion and winding
- These are power efficient, thus providing significant monetary savings in the long run
- The machines are also resistant to moisture and UV rays
- Laser cutting machines have a long service life and require minimal maintenance, with only a periodic inspection and servicing of parts of these machines being enough
Basic Working Mechanism of Laser Cutting Machines:
- A high intensity beam of infrared light is generated by a laser
- The particular light is then focused on the surface of the workpiece to be cut through a lens
- The focused beam then heats the workpiece and ensures a very localized melt throughout it's depth
- The molten material is afterwards ejected from the area through a pressurized gas jet that acts co-axially with the laser beam
- The material which has been removed is moved across the surface of the sheet, as a result generating a cut
