Optimizing the machining time

After simulating a program, the machining time is displayed for the blocks.
For a multi-channel display, the wait times that occur are displayed at the wait points (wait
marks). This provides you with an overview of the time sequence of the program and you
can perform the first optimization runs.
Shifting blocks
For instance, you have the option of shifting program blocks to longer wait points - assuming
that the machining technology permits this - therefore reducing the machining time.
Time-related view
The wait time at the wait marks is displayed in seconds.
The total runtime is displayed at the end of the program.
If you change the program, time data is still displayed at the corresponding wait marks or the
corresponding blocks dimmed.
The determined times are kept if you change, shift or copy the program blocks.
The determined times are lost if you exit the editor using the "Close" softkey or you open or
select another program. The data must be determined again through simulation.
