What are the Benefits and Drawbacks of Laser Cutting

During mechanical cutting, by saw, for example, machines can be contaminated by the materials they are cutting and can also be dulled by frequent extended use. 

Precision in laser beams is also higher than that of typical industrial cutting materials. In short, custom laser cutting produces greater consistency from part to part. Laser cutting gives you cleaner, burr-free cuts, quicker production, minimal operator intervention (so less human error), and greater accuracy means less wasted metal and lower costs to the manufacturer. 

Mechanical cutting is simple machining but requires less energy than does laser cutting, the main weakness in the process. Also, the laser cutting process requires cooling. Water is a commonly used coolant, usually circulated through a chiller or heat transfer system.

What are the Types of Laser Cutting?

There are three main types of laser cutting. The CO2 laser is used to cut, bore, or engrave. Nd is used for boring when there are high-energy requirements but low repetition. 

Nd-YAG laser is used where high power is needed. Both are used for welding. A typical laser machining apparatus consists of a power supply for producing a laser beam, a work piece positioning table, laser material, a method of stimulation, mirrors, and a focusing lens.

The work piece is fixated by straps, clamps, tabs, magnets, or suction cups.
