2.3 Process-Specific Programming
The CNC is organized into a maximum of 7 processes. Each process has
its own NC-block preparation which combines the data from the NC-pro-
gram with data such as zero points, Setup Lists, etc.
The number of processes is declared in the system parameters. Or if
more than 2 processes are declared, process 0 is generally used to syn-
chronize the other processes.
Example
Use of a number of processes on a double-slide single-spindle lathe with
a milling head:
•
Process 0
Synchronization of processes 1 and 2, coordinates whether the proc-
esses are working simultaneously and asynchronously or synchro-
nously.
•
Process 1
Process 1 contains the X and Z axes for the upper turret head.
•
Process 2
Process 2 contains the X and Z axes for the lower turret head, the
main spindle S1, the C axis, and spindle S2 as the driven tool spindle.
