Complete program
Complete programs contain both the basic settings, such as work
offset, tool call, etc. and the geometry values of the free-form
surfaces to be machined. However, programming optimum
velocity control is very complicated in a complete program.
Complete programs are also created on external CAM systems.
Because of their size, the complete programs are stored on the
hard disk of the PCU 50 or on the compact flash card of the
PCU 20.
Storage on a network drive is also only recommended for a point-
to-point connection between the control and server.
