What is laser micromachining?

What is laser micromachining?

Laser micromachining (also laser beam micro-machining) means laser machining of very fine structures, typically on a scale between a few microns and a few hundred microns. The machined parts are not always very small, but at least the structures (e.g. holes, grooves or patterns) made on them.

What is excimer laser micromachining?

Abstract: An excimer laser three-dimensional (3D) micromachining system is proposed based on a mask image projection method and the optical diffraction effect. The practical feasibility of the proposed method is demonstrated by machining conical, trihedral, and pyramidal 3D microstructures on polycarbonate substrates.

What is laser machining process?

Laser machining processes involve the use of conventional and fiber optic beam delivery systems, which allow precision positioning while ablating/cutting materials. They are used to cut burr-free parts that are required in a number of industries. The process is efficient and fast.

How does laser micromachining work?

Ultrafast laser micromachining is a process by which pulses from an ultrafast (pulse duration less than a few picoseconds) laser are used to induce micrometer-sized structures on the surface or in the bulk of solid materials.

What polymeric materials is commonly used in micromachining processes?

Polyethylene a thermoplastic polymer is one of the most popular materials used in consumer applications.

What are the applications of laser machining?

Applications. Lasers can be used for welding, cladding, marking, surface treatment, drilling, and cutting among other manufacturing processes. It is used in the automobile, shipbuilding, aerospace, steel, electronics, and medical industries for precision machining of complex parts.

How many laser processes are there?

A continuous cut is produced by moving the laser beam or workpiece under CNC control. There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting. In fusion cutting, an inert gas (typically nitrogen) is used to expel molten material out of the kerf.

Why is femtosecond laser used for micromachining?

The advantages of femtosecond laser micromachining include non-contact machining with high peak powers. It has minimal or lesser thermal damage to its materials or surroundings. It also offers a high aspect ratio clean cuts, features sub-micron resolution, and minimal redeposition.

What is the difference between bulk micromachining and surface micromachining?

Bulk micromachining is a process used to produce micromachinery or microelectromechanical systems (MEMS). Whereas surface micromachining creates structures on top of a substrate, bulk micromachining produces structures inside a substrate.

How many types of micromachining are there?

Three widely used MEMS fabrication methods are • surface micromachining, • bulk micromachining, and • LIGA (Lithography, Galvanoformung (electroforming), and Abformung (molding).

What industries use laser cutting?

Laser cutting is now one of the most commonly used manufacturing processes throughout the world. You can find this utilised in the engineering, electronics, automotive and aerospace industries.

What industries use laser technology?

Industrial lasers are used to cut metals and fabrics, mark tracking codes for industrial traceability, weld metals with high precision, clean metal surfaces, change the surface roughness, and measure part dimensions. They are widely used in several industries such as the EV and primary metals industries.
