Laser Machining
By Ross Bainbridge

Laser machining technology uses high intensity laser beams of varying widths for a variety of applications such as slotting, cutting, and creating holes. It can be used in fabrication of different types of materials such as metals, plastics, vinyl, glass, marble, and graphite. Other materials that can be fabricated using laser machining include nylon, ceramics, carbon fiber, composites, soft rubber, and thin metal foils.

Laser machining systems are used in conjunction with computer numeric control (CNC), which makes it ideal for use with thin walled tubing, boasting beam widths down to .0005'. In this process, the machining operator uses computers to control machine tools for manufacturing complex and intricate parts in metal and other materials.

A laser machining process involves the use of conventional as well as fiber optic beam delivery systems, which allow precision positioning while cutting metal or other materials. It is used to cut burr-free parts that are required in a number of industries such as aerospace, automobile, shipping, and others. The process is fast, efficient, and can be repeated any number of times depending on production volumes. It is used to create grooves that are cut to a specific depth with one pass of a laser beam without severing any material from the work piece.

Laser machining is used for producing a knurled or roughened surface on hard materials such as metals and fragile materials such as ceramics and glass. The technology is also used for marking material surfaces. In the process a high intensity laser beam is passed through a stencil of a mirror and onto the area of the material or work piece that is being marked.

Research is underway to develop advanced laser machining techniques that will allow the production of microscopic devices for use in medical industry. This will help in fighting deadly diseases such as cancer in the near future.
