• G331/G332 causes the spindle to be interpolated as an axis in a path grouping. In the
case of tapping, the drilling depth (e.g., axis X) and the pitch and speed (e.g., spindle S)
are specified.
In the case of DryRun, the velocity of X is specified, the speed remains constant, and the
pitch is adjusted.
Following the SERUPRO simulation, the position for spindle S deviates from the normal
position because the spindle S has rotated less during simulation.
2.6.3 SERUPRO ASUP
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 statement
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
statement into account!
Tool management
If tool management is active, the following setting is recommended:
Set MD18080 $MA_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 are changed.
•
Tool data are not changed.
Exception:
The tool enabled during the test mode can assume 'active' status. As a result, the spindle
may contain the incorrect tool 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 point 7.
