Block search mode Meaning
With calculation
- without approach 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.
With calculation
- with approach 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:
In a ShopMill program, the search is only performed on G code-blocks.
With calculation
- skip extcall This is used to speed-up a search with calculation when using EXTCALL
programs: EXTCALL programs are not taken into account.
Notice: Important information, e.g. modal functions, which are located in the
EXTCALL program, are not taken into account. In this case, after the search
target has been found, the program is not able to be executed. Such infor‐
mation should be programmed in the main program.
