4.2 Running a G code program
During execution of a program, the workpiece is machined in
accordance with the programming on the machine.
After the program is started in automatic mode, workpiece machining
is performed automatically. You can, however, stop the program at
any time and then resume execution later.
Execution of the program can be simulated graphically on the screen
to enable you to check the programming result without moving the
machine axes.
For more information about simulation, see Sec. "Simulation".
The following requirements must be met before executing a program
on the machine:
• The measuring system of the control is synchronized with the
machine.
• A program created in G code is available.
• The necessary tool offsets and work offsets have been entered.
• The necessary safety interlocks implemented by the machine
manufacturer are activated.
When executing a G code program, the same functions are available
as for executing a sequential control program (see Sec. "Machining a
workpiece").
Simulating a G code
