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.

In the associated selection field of a channel, select "Yes" if the WAIT

mark for this channel is to be valid.

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

Select the block that you wish to shift.

Press the "Mark" softkey.

Press the "Copy" softkey if you wish to repeat the machining step at

another position.

Press the "Cut-out" softkey if you wish to execute the machining step at

another position.

Position the cursor at the required program position and press the

"Paste" softkey.

Insert the program block at the required position.
