Meaning
In order to be able to approach a target position in any circumstance (e.g. tool
change position).
The end position of the target block or the next programmed position is ap‐
proached using the type of interpolation valid in the target block. Only the axes
programmed in the target block are moved.
Note:
If machine data 11450.1=1 is set, the rotary axes of the active swivel data
record are pre-positioned after the block search.
It is used to be able to approach the contour in any circumstance.
The end position of the block prior to the target block is found with <CYCLE
START>. The program runs in the same way as in normal program process‐
ing.
Note:
This block search mode should only be used in exceptional cases if machin‐
ing was directly interrupted at the workpiece - and machining is to directly
continue at the workpiece again.
For a ShopTurn program, this block search mode can only be performed on
G code blocks.
If possible, the block search mode "with calculation - without approach"
should be used.
