9.8 Block search Type 5 (SERUPRO)
Rigid tapping
● With "rigid tapping" (G331/G332), the spindle is interpolated under position control in a path
grouping. The drilling depth (linear axis), the thread pitch, and speed (spindle) are defined.
During dry run, the velocity of the linear axis is specified, the speed remains constant, and
the pitch is adjusted.
After SERUPRO, a position for the spindle results that is deviates from normal mode
because the spindle has revolved fewer times in SERUPRO.

SERUPRO ASUB

SERUPRO ASUB special points
Special points should be noted for SERUPRO ASUB with regard to:
● Reference point approach: Referencing via part program G74
● Tool management: Tool change and magazine data
● Spindle ramp-up: On starting a SERUPRO ASUB
G74 reference point approach
If command G74 (reference point approach) is programmed between the program start and
the search target, this will be ignored by the NC.
SERUPRO approach does not take this G74 command into account!
Tool management
If tool management is active, the following setting is recommended:
MD20310 $MC_TOOL_MANAGEMENT_MASK Bit 20 = 0
The tool management command generated during the SERUPRO operation is thus not output
to the PLC!
The tool management command has the following effect:
● The NC acknowledges the commands automatically.
● No magazine data is changed.
● Tool data is not changed.
Exception:
The tool enabled during the test mode can assume 'active' state. In this way, the wrong tool
may be on the spindle after the SERUPRO operation.
Remedy:
The user starts a SERUPRO ASUB that is actually traversed. Prior to the start, the user
can start an ASUB that loads the correct tool.
SERUPRO operation: Functionality: In sequence steps 2. to 6.
SERUPRO ASUB: Functionality: The sequence of step 7.
