Setting Up for Cutting, purity of the beam by stray reflections off mirror mounts, etc. Once the beam is focused onto the workpiece in its purest possible state, it is then necessary to establish the focal position exactly and correctly locate this with respect to the material surface. The last step is to make sure the fo

Troubleshooting,itably arise from time to time. Most of the problems are related to incorrect parameter settings (power etc.) or the accumulation of dirt on optical components and the nozzle. This section hopes to guide the way to the most effective method of tracking down a problem and then eliminating it.

Safety Guidelines,ise if maintenance work of any sort is carried out. The major danger to life is the high voltage system used to generate the electric discharge, and this should be worked on exclusively by well trained service personnel. This and other aspects of safety will be discussed under four main headings:

The work which has been carried out so far has led to the rapid growth of the industry and from a practical point of view a deeper understanding may have only a small effect on future industrial development.
