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
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
In the time-related view, the wait times at the WAIT marks as well as the required machining
times at the machining sections are displayed. If you change the program, time data is still
displayed at the corresponding wait marks or the corresponding blocks dimmed.
The determined times are lost if you exit the editor using the "Close" softkey or you open or
select another program. The times must be determined again through simulation.

7. Press the "Accept" softkey.
The WAIT mark is displayed in the program as machining step.
Using "Cursor right", as usual, open the machining step in the editor.
+ Press the keys <SHIFT> and <INSERT > to open the WAIT mark and
edit it.
1. Select the block that you wish to shift.
2. Press the "Mark" softkey.
3. Press the "Copy" softkey if you wish to repeat the machining step at
another position.
- OR -
Press the "Cut-out" softkey if you wish to execute the machining step at
another position.
4. Position the cursor at the required program position and press the
"Paste" softkey.
Insert the program block at the required position.
