how does a laser cut a sheet of polymer

Laser cutting of polymer tubes - NKT Photonics- how does a laser cut a sheet of polymer ,The use of ultrafast lasers in the fabrication of polymer medical devices has gained wide acceptance within recent years. Unlike mechanical methods, laser cutting has the ability to create fine, precisely machined features and markings. Through the non-contact process, a consistent high-quality cut is ensured at a high yield and low cost. Because ultrafast lasers can process a wide variety of polymers, regardless of transparency or thickness, you can simplify the manufacturing process. Sheet Metal Laser Cutting: Fundaments of Laser Cutting MetalLaser cutting is a technology that involves using a laser to cut materials. This makes it an important process in sheet metal fabrication where it goes as sheet metal laser cutting. Laser cutting is essential because of its compatibility, high precision cutting, and quality assurance. This article will talk about laser cutting, its history, types.

This method of acrylic laser cutting involves focusing the beam on the surface of the material. It then results in localized heating which in turn leads to thermal expansion. The resultant effect of this is that crack develops directed by moving the beam. You can as well choose to move the crack in the order of m/s.

How does laser cutting work? | FAQ Trotec Laser

Laser cutting is a type of thermal separation process. The laser beam hits the surface of the material and heats it so strongly that it melts or completely vaporizes. Once the laser beam has completely penetrated the material at one point, the actual cutting process begins. The laser system follows the selected geometry and separates the material in the process.

CO2 laser principle. During the cutting process, gas is emitted. When cutting mild steel, pure oxygen is released to start a burning process. In case of stainless steel or laser cutting aluminium, the laser beam just melts the metal. The cutting gas is then nitrogen, to blow out the molten metal and keep the cuts clean.
