The geometric task is implemented by three main
modules: the interpreter of part programs, the
interpolator, the control module of servo drives. Despite
the fact that the interpolator has a modular architecture,
its configuration or extension for specific tasks is rather
difficult, because it is available only for the
manufacturer of control systems. In rare cases, this right
may be granted to machine builders, but not completely
[12, 13]. In this article a special approach of building a
CNC system with an opportunity to add motion control
methods for laser processing without modifying the
system architecture is proposed [14].
The work area of laser scanning head is restricted to
300 x 300 mm. To cover completely the work piece it is
necessary to have a servo drive movement
