The laser has given manufacturing industry a new tool. When the laser
beam is focused it can generate one of the world's most intense energy
sources, more intense than flames and arcs, though similar to an
electron beam. In fact the intensity is such that it can vaporise most
known materials. The laser material processing industry has been growing
swiftly as the quality, speed and new manufacturing possibilities become
better understood. In the fore of these new technologies is the process
of laser cutting. Laser cutting leads because it is a direct process
substitu- tion and the laser can usually do the job with greater
flexibility, speed and quality than its competitors. However, to achieve
these high speeds with high quality con- siderable know how and
experience is required. This information is usually carefully guarded by
the businesses concerned and has to be gained by hard experience and
technical understanding. Yet in this book John Powell explains in lucid
and almost non- technical language many of these process wrinkles
concerning alignment, cornering, pulsing, water jets, material
properties, cutting speeds as well as tricks with surface coating and
much much more. It is a book which managers and technicians in laser job
shops and laser processing facilities would be foolish not to read.
