A process model is set up in order to describe and analyze the relations between the parameters and
variables of the process. On figure 3.2 a general model of a process is seen. It can be seen that both
controllable and uncontrollable parameters have an effect on the output of the process. This also applies
to the laser cutting process, where uncontrollable parameters includes specific properties of the laser
cutting setup. By using the general process model it is possible to describe what affects the quality of the
cut. In this thesis it is defined, that the inputs to the model, is in form of control variables, the uncontrollable
parameters are equipment parameters, the controllable parameters are workpiece parameters and
the output is the quality of the cut described through quality parameters.
Through this thesis the definition of the inputs, controllable/uncontrollable parameters and output for the
process model is:
