What is Laser Cutting?
It’s a method for making precise patterns in a wide variety of materials. A typical process laser has a beam about a 1/5 of a millimeter in width, focusing 1000 to 2000 watts of energy. This is enough to melt most common materials. Because lasers become less focused and lose energy as they penetrate through a material, there is a limit of about 20 mm for the deepness of the cut. Laser machines are integrated into a larger CAD/CAM (computer-aided-design, computer-aided-manufacturing) system that takes a design file and implements it on a workpiece. These machines represent a stepping stone in the continuing trend away from hands-on manufacturing, putting human workers in a more removed, creative design role.
All About Laser Cutting
from Fedtech, 3 years ago in Business & Mgmt
Laser cutting uses a resonator to create a beam of light. The light is transmitted through a series of mirrors to a cutting head. It then goes through a lens that focuses the laser beam through a diameter of roughly .015″. This is what is used to cut through the material of choice.
According to Wiki, it’s a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.
Laser Cutting Guide for Manufacturing
Charles L. Caristan, published 2004, 447 pages
Laser Cutter Guide for Manufacturing presents practical information and troubleshooting and design tools from a quality manufacturing perspective. Equally applicable to small shops as it is to large fabricator companies, this guide is a road map for developing, implementing, operating, and maintaining a laser-cutting manufacturing enterprise. The book focuses on metal cutting of sheets, plates, tubes, and 3-D shaped stampings. It presents today’s reality of the engineering and business challenges, and opportunities presented by the rapid penetration cutting in all facets of industry.
