Block scan
Refer to your machine manual.
This function must be set up by your machine
manufacturer.
Block scan (mid-program startup) is not available for
Reference machining operations required during
(optional) load monitoring .
Mid-program startup means starting an NC program at a selected
point. In smart.Turn programs, you can start the program at any NC
block.
The control starts program run from the cursor position. The
starting position is not changed by a previous graphic simulation.
In the execNextStartBlock machine parameter (601810),
you can define whether program run after a block scan
will start at the selected NC block or at the subsequent
NC block.
NOTICE
Danger of collision!
The control brings the machine into the situation in which it
would be in a normal program run just before the startup block
(e.g. previous tool or previous tilting situation). There is a danger
of collision during the tilting movement and the rotation!
Pre-position the slide so that the tool carrier (e.g. turret) can
tilt without collision
Pre-position the slide so that the axes are able to move to the
last programmed position before reentry without collision
HEIDENHAIN recommends starting at an NC block immediately
after a
T
command.
The control restores the previous machine situation by
proceeding in the following sequence:
Insert the tool
Position the axes in the configured or selected sequence
Switch the spindle on
