An Excimer laser is an ultraviolet-based laser, it is used in producing microstructures. It uses a combination of reactive and inert gases to produce a beam. At times it is also referred to as the ultraviolet chemical laser.
Cutting Depth of a laser:
It is represented by the following equation :
t =depth of cut
P = laser beam power
v = cutting velocity
d = laser beam spot diameter
Applications of laser machining :
Laser Beam Machining can be used for cladding, cutting, welding and drilling. It finds wide applications in various industries like space tech, automobiles, avionics, shipbuilding and many others manufacturing process. Laser welding is by far the most efficient and fast welding technique ever. It can ever weld at speeds up to 100 mm/sec.
Laser cladding is used to provide a protective cover to the damaged surface. It is one of the cheapest ways to offer protective cladding till date, not to mention one of the fastest too. Drilling and cutting using lasers as a tool have a distinct advantage that there is no wear and tear of the drilling equipment. It is also a very cheap alternative to traditional drilling tools. Saves lots of time and money. In most of the modern industrial applications, we would find laser machining working in tandem with traditional machining. This mix of machining results in a more efficient and economic machining process. The best application of laser beam machining is in working in high precision environments. The laser can work where traditional machining cannot.
